Shares in a company can be freely transferable. When a member transfers his shares to another person, the transferee becomes the shareholder of the company.

(4) Common Seal:
A company is an artificial person and does not have a physical presence. So the common seal is necessary because the company cannot sign the documents. It is the official signature of the company.

(5) One Share – One Vote:
The principle of voting in a company is one share – one vote. If a person has 10 shares, he has 10 votes in the company. So in a company, money is given more importance than a man.

Question 1.
Solve
(i) \(\frac{d y}{d x}=a e^{y}\)
(ii) \(\frac{1+x^{2}}{1+y}=x y \frac{d y}{d x}\)
Solution:

Question 2.
Solve: y(1 – x) – x \(\frac{d y}{d x}\) = 0
Solution:
y(1 – x) – x \(\frac{d y}{d x}\) = 0
Separating the variables,

log x – x = log y + c is the general solution

Question 3.
Solve:
(i) y dx – x dy = 0
(ii) \(\frac{d y}{d x}\) + e^x + y e^x = 0
Solution:
(i) y dx – x dy = 0
Separating the variables,
y dx = x dy

Integrating,
\(\int \frac{1}{y+1} d y=\int-e^{x} d x\)
log (y + 1) = -e^x + c is the general solution

Question 4.
Solve: cos x (1 + cos y) dx + sin y (1 + sin x) dy = 0
Solution:
cos x (1 + cos y) dx + sin y (1 + sin x) dy = 0
Separating the variables,
cos x (1 + cos y) dx = -sin y (1 + sin x) dy

Question 5.
Solve: (1 – x) dy – (1 + y) dx = 0
Solution:
(1 – x) dy – (1 + y) dx = 0
Separating the variables,
(1 – x)dy = (1 + y) dx
\(\frac{d y}{1+y}=\frac{d x}{1-x}\)
Integrating, we get
\(\int \frac{1}{1+y} d y=\int \frac{1}{1-x} d x\)
log(y + 1) = -log(1 – x) + log c
log(y + 1) + log(1 – x) = log c
(y + 1) (1 – x) = c

Question 6.
Solve:
(i) \(\frac{d y}{d x}\) = y sin 2x
(ii) log(\(\frac{d y}{d x}\)) = ax + by
Solution:
(i) \(\frac{d y}{d x}\) = y sin 2x
Separating the variables, \(\frac{d y}{y}\) = sin 2x dx
Integrating, we get
∫\(\frac{1}{y}\) dy = ∫sin 2x dx
log y = \(-\frac{\cos 2 x}{2}+c\) is the required solution

Question 7.
Find the curve whose gradient at any point P(x, y) on it is \(\frac{x-a}{y-b}\) and which passes through the origin.
Solution:
The gradient at any point P (x, y) on the curve is given by \(\frac{d y}{d x}\)
According to the problem
\(\frac{d y}{d x}=\frac{x-a}{y-b}\)
Separating the variables,
(y – b) dy = (x – a) dx
Integrating,
∫(y – b) dy = ∫(x – a) dx

(or) (y – b)² = (x – a)² + b² – a² is the required equation of the curve.

Differentiating (1) w.r.t x, we get
2(y – β) \(\frac{d y}{d x}\) = 4a ……. (2)
Again, differentiating (2) w.r.t x, we get

Question 6.
Find the differential equation of all circles passing through the origin and having their centers on the y-axis.
Solution:

The circles pass through the origin. They have their centres at (o, a)
The circles have radius a. so the equation of the family of circles is given by
x² + (y – a)² = a²
x² + y² – 2ay + a² = a²
x² + y² = 2ay ……. (1)
Differentiating w.r.t x,

II. 2 Mark Questions

Question 1.
Find the area bounded by the curve y² = x³ and the lines x = 0, y = 1 and y = 2
Solution:

Question 2.
Find the area bounded by one arch of the curve y = sin ax and the x-axis.
Solution:

Question 3.
The marginal cost of a commodity is 3x² – 2x + 8. If there is no fixed cost find the total cost.
Solution:
C = ∫(MC) dx + k
= ∫(3x² – 2x + 8) dx + k
= x³ – x² + 8x + k
No fixed cost ⇒ k = 0
So total cost, C = x³ – x² + 8x

Question 4.
For the marginal revenue function MR = 3 – 2x – x², find the revenue function and demand function.
Solution:

Question 5.
The marginal cost at a production level of x units is C'(x) = 85 + \(\frac{375}{x^{2}}\). Find the cost of producing 10 extra units, after 15 units have been produced.
Solution:

But 15 units have been produced. We have to find the extra cost for 10 units that is, from 15 to 25 units. Hence

Required cost is ₹860

III. 3 and 5 Marks Questions

Question 1.
Find the area under the curve y = 4x² – 8x + 6 bounded by the y-axis, x-axis and the ordinate at x = 2.
Solution:
The shaded area is given by \(\int_{0}^{2} y d x\)

Question 2.
The marginal revenue for a commodity is MR = \(\frac{e^{x}}{100}+x+x^{2}\). Find the revenue function.
Solution:

Question 3.
The elasticity of demand with respect to price p is \(\frac{x-5}{x}\) x > 5. Find the demand function if the price is 2 when demand is 7. Also find the revenue function.
Solution:

⇒ log (x – 5) = -log p + log k
⇒ log (x – 5) + log p = log k
⇒ p (x – 5) = k
When p = 2, x = 1 ⇒ k = 4
Demand function is P = \(\frac{4}{x-5}\)
Revenue R = px or R = \(\frac{4x}{x-5}\), x > 5

Question 4.
The marginal cost and marginal revenue of a commodity are given by C'(x) = 4 + 0.08x and R'(x) = 12. Find the total profit, given that the total cost at zero output is zero.
Solution:
Given that, MC = 4 + 0.08x
C(x) = ∫(4 + 0.08x) dx + k₁
= 4x + 0.08\(\frac{x^{2}}{2}\) + k₁
= 4x + 0.04x² + k₁
But given when x = 0, C = 0, So k₁ = 0
C(x) = 4x + 0.04x²
Now given that MR = 12
R(x) = ∫12 dx + k₂ = 12x + k₂
Revenue R = 0 when x = 0 ⇒ k₂ = 0
R(x) = 12x
Total profit function P(x) = R(x) – C(x)
= 12x – 4x – 0.04x²
= 8x – 0.04x²

Question 5.
The marginal cost C'(x) and marginal revenue R'(x) are given by C'(x) = 20 + \(\frac{x}{20}\) and R’ (x) = 30. The fixed cost is ₹ 200. Find the maximum profit.
Solution:

Question 6.
The marginal cost of producing x units is C'(x) = 10.6x. The fixed cost is ₹ 50. The selling price per unit is Rs.5. Find (i) total cost function
(ii) total revenue function and
(iii) profit function.
Solution:
Given C'(x) = 10.6x
C'(x) = ∫(10.6x) dx + k
= 10.6\(\frac{x^{2}}{2}\) + k
= 5.3x² + k
The fixed cost is ₹ 50
(i.e.) when x = 0, c = 50 ⇒ k = 50
Hence cost function C = 5.3x² + 50
Now, total revenue = number of units sold × price/unit
Since x be the number of units sold.
The selling price is Rs.5 per unit.
Revenue R(x) = 5x
Profit P = Total revenue – Total cost
= 5x – (5.3x² + 50)
= 5x – 5.3x² – 50

Question 7.
The demand and supply functions under pure competition are p_d = 16 – x² and p_s = 2x² + 4. Find the consumer’s surplus and producers’ surplus at the market equilibrium price.

Context: The poet says these while contemplating the probability of swapping places with them.

Explanation: The poet has limp and bashful spirit which feeds on other people’s heroic deeds. The zealous players maim one another to win laurels. The thrill and excitement of all kinds of sports and games pleases the poet but he is wise enough to stay out and be a spectator because he has modest of physiques. He admits he would rather share a drink with them in a pub or dine with them in a restaurant.

PART – IV

IV. Answer the following: [7 × 5 = 35]

Question 41.
How does the author prove that absent-mindedness is a boon as well as a bane?
Answer:
Absent – mindedness of people shocked the author when the Railway department published the list of lost articles. It was startling to note that young people forget bats, balls etc. The author attributes it to the abundant imagination and dreams. They are citizens of dreamland. Anglers also forget their fishing rods. Absent – mindedness is often a blessing in disguise. People can forget their unhappiness and live in a world of Utopia. Great thinkers, poets and philosophers are absent – minded because their minds are full of lofty ideas and imagination.

Socrates the philosopher and S.T. Coleridge the poet were absent – minded people. Similarly, Politicians have bad memories. States are yet to produce ideal statesmen who can remember their promises after winning the elections. Great writers, composers of music have amazingly great memories. Memory is half the substance of their art. Once a father took his baby out in a perambulator in the morning. He walked into a pub to have a glass of beer. The child was sitting in the perambulator outside in the street. After sometime, his wife came that way for shopping. She was shocked to find her baby sleeping in the perambulator.

She decided to teach her husband a lesson. She took the baby home. She expected her husband to come and apologize for losing the child. But he just walked in and casually asked his wife cheerfully what was there for lunch. Very few people like Einstein or Socrates would be capable of such absent-mindedness. Men should forget unpleasant things and remember pleasant things. Thus Absent – mindedness is both a boon and a bane.

[OR]

How does the speaker highlight the importance of giving back to the society?
Answer:
The graduates have drawn largely from the social chest. The largest taken from the society needs to be replenished. If graduates fail to pay back, ordinary people’s coffer will be empty. The supervisor’s education enjoins greater responsibility to society. Apart from their own individual advancement, society has got a right to expect an adequate return from the graduates.

The society does not expect them to payback in cash. But they must pay back in terms of service. They should tone up the society by bringing a light into the dark alleys. They should herald sunshine into dingy places. They must give solace to the affiliated people. They should also give hope unto the despondent and thus ensure a new life unto everyone.

Question 42.
‘Face is the index of the mind.’ Does this adage concur with the views of the poet?
Answer:
Unlike the people of the past, people in modem times “laugh only with their teeth” while their ice-block cold eyes search for something. Now, people shake hands without hearts. There is no human warmth in social relations. While they shake hands, they look for evidences to judge the financial status of a person. People say ‘feel at home’ and ‘come again’. But if a person visits a third time he is not welcomed. They all have cocktail faces ready for all occasions. Their conforming smiles are like fixed portrait smiles.

They wear standard, deceitful, artificial smile for all occasions. They have faces like masks. The poet has learnt from them how to use faces like dresses, home face, office face, street face, host face etc. Their faces, like the teeth of the elephant, show only what is accepted. The ugly side of their personality is cleverly hidden behind their deceitful smiles and polite words. So, the poet’s views do not concur with the adage “Face is the index of the mind”.

[OR]

In what way is every hillock similar to Everest?
Answer:
The poet does not compare rare feats of athletes, mountaineers or horsemen. He does not attach great value to positions or possessions. He scoffs at those who pull strings to achieve their ends. The means must justify the ends. One should not stoop to underhand dealings to-achieve their desired goals in life.

Those who reach great heights in life like Everest due to their hard work, perseverance and competence are adorable. At the same time those who trek any small hillocks can’t be underestimated. The efforts made in reaching even the smallest positions in life, if done with sincerity of purpose and deep devotion, is worthy of hearty appreciation. One who holds a humble position, but upright and serves as a ladder for fellow humans to reach great heights deserves our respect.

The poet admits that he is proud of people’s humble positions because their pride springs not from positions or possessions but the way they live. Their life knows no bending. The poet just doesn’t bother the height of the peak one reaches. It could even be a hillock. What matters is how one reaches that spot. If merit and competence have paved the way for their success and positions, however humble they are, the poet admires them.

Question 43.
Write a paragraph (150 words) by developing the following hints.
A policeman – dow n the street – checking doors – a man standing – stops to talk – about the childhood friends who agreed to meet – after 20 years – his friend there shows up – how each of them has changed – The criminal – arrested, and the undercover cop says – 20 years – change a good man into a criminal.
Answer:
The short story “After Twenty Years” takes place around 10 p.m. along a dark, windy New York City business avenue, mostly within the darkened doorway of a closed hardware store. This particular location had been a restaurant until five years ago. The plot begins with a policeman “on the beat” who discovers a man standing in the dark doorway.

The man then proceeds to explain why he is there. He and his best friend, Jimmy Wells had parted exactly twenty years ago to make their fortunes and had promised to meet at that spot “After Twenty Years”. He had gone west and gotten rich and was sure his friend, Jimmy would meet him if he were alive. They talked a while and the policeman carried on. The man from the west wonders if his friend will come. The drama increases in anticipation of the rendezvous.

Twenty minutes later, another man, whom we assume is his long lost friend, greets him warmly and they walk arm in arm discussing careers until they come to a well-lit comer near a drug store. The man from the west gets a good look at his companion and discovers that he is not his friend, Jimmy. We are treated to several surprises for the man from the west is under arrest and secondly he is actually ‘Silky Bob’, a gangster from Chicago and finally the stranger is a plainclothes policeman. However, it seems that these three surprises are not enough. We get the “real” surprise when Jimmy Wells, the original policeman didn’t have the heart to arrest Bob, because he was his friend.

Narrator – wants – photograph – photographer wait for an hour – comments – angry – called on Saturday – proof – Narrator shocked – photograph – not like him – worthless bauble.
Answer:
‘With the Photographer’ by Stephen Leacock is narrated in the first person. The narrator while sitting in the photographer’s studio begins to read some magazines and sees how other people look and the narrator begins to feel insecure about his appearance. It is also noticeable that the photographer takes a dislike to his face judging it to be wrong. What should have been a simple process of taking a photograph becomes something of a nightmare for the narrator.

How confident the narrator becomes is noticeable when he returns to the photographer’s studio the following Saturday. He realises that the photograph that has been taken of him looks nothing like him. This angers the narrator as he was simply looking for a photograph that would show his likeness. He accepts that he may not be to everybody’s liking when it comes to his physical appearance but is angered by the changes made. The photographer has retouched the photograph so much that the narrator does not recognise himself.

The end of the story is also interesting as the reader realises that it is just a worthless bauble when he begins to cry. He has been judged solely by his appearance by the photographer whose job was to simply take a life like photograph.

Question 44.
Write a summary or Make notes of the following passage.
Any polished surface which reflects light is a mirror. Most mirrors are made of smooth glass. These glass strips are backed with a very thin layer of aluminium. Not all mirrors are flat. Convex mirrors bulge outwards. They make things look smaller. But they give us a wider view. They are often used as driving mirrors in cars. They are also used as security mirror in shops. Concave mirrors curve in wards. They are used as shaving mirrors, because they magnify things which are close. With distant things, they produce a tiny upside – down image. In large telescopes they are used to collect and focus the light.

Write an essay in about 150 words on ‘Disaster Management in India’.
Answer:
Disaster Management in India
National Institute of Disaster Management is a premier national institute. It trains people for capacity development programmes for managing natural disasters in India. The NIDM works under government’s directives to train and conduct checks to regulate effective earthquake and disaster control policies. Recently, Delhi witnessed One of the biggest mega mock drills conducted by the NIDM in India.

The buildings and infrastructures in India are quite vulnerable to calamities. They can’t withstand the rigours of a natural calamity. The Tsunami disasters in South India expose the unpreparedness and lack of skills in disaster management. The havoc caused by the floods and landslides in Kerdamath only underlines our weakness or inefficiency in tackling natural disaster on such a scale.

The NIDM can take due credit for its efficient work done during the ‘Hudhud’ cyclone. The cyclone struck the coastal areas of Andhra and Odisha. Proper warning and early evacuation in the affected areas limited losses and casualties. But again the NIDM proved quite ineffective when unprecedented floods rocked Srinagar and other parts of Jammu and Kashmir. It was the army and not the NIDM that stole the limelight by evacuating lakhs of marooned people and saving their lives.

The NIDM has a long way to go. It must prepare itself as a body that can cope with natural disasters with professional skills and efficiency.

Read the following passage carefully and answer the questions that follow.
The first flags were probably hoisted in China. People flew flags in China over 4,000 years ago. Each part of the army had its own flag so the soldiers could see their leaders. Early flags were sticks of wood. They had pictures cut into the wood. Iran had metal flags about 3,000 years ago. Old Greek coins show pictures of flags. People in Rome also used flags over 2,000 years ago. People first made flags of cloth about 2,000 years ago. Those flags looked like today’s flags. Flags are important at sea. Most ships fly their own country’s flag and the flag of the country they are visiting. When a ship flies only its own flag, it is ready to fight.

Every country now has a flag. Every U.S. state has a flag. Clubs, teams, and schools have flags. The Olympics has a flag. The Olympics flag has five rings of five colours. Each ring stands for, or represents, a continent. It means that people from five continents – Africa, Asia, Europe, North America and South America – come to play. Railway lines also use flags. Railway flags tell the trains what to do. For example, a red flag tells the train to stop, just like a stop sign. A blue, white, or green flag tells the train that it can go. A blue flag on the side of a train means someone is working on the train. It means nobody can move the train.
Questions.

1. How many flags do most ships fly?
2. What were the first flags made of ?
3. Does every country have a flag?
4. Mention the role of a railway flag.
5. Describe the Olympic flag.
6. Answer:
7. Most ships fly two flags. One is of their own country and another is that of the country it intends to visit.
8. The first flags were made of sticks of wood.
9. Yes, every country has a flag.
10. A railway flag directs a train to stop or move forward. Red flag tells the train to stop. White, blue and green ones allow the train to pass. However, a blue flag on the side of a train indicates a technical problem with the train.
11. Olympic flag has five rings of colors explaining the representation of people from five continents (i.e.) Africa, Asia, Europe, North America and South America.

Tamilnadu Samacheer Kalvi 12th Business Maths Solutions Chapter 3 Integral Calculus II Ex 3.2

Question 1.
The cost of an overhaul of an engine is ₹ 10,000 The operating cost per hour is at the rate of 2x – 240 where the engine has run x km. Find out the total cost if the engine runs for 300 hours after overhaul.
Solution:
Given that the overhaul cost is Rs. 10,000.
The marginal cost is 2x – 240
MC = 2x – 240
C = ∫ MC dx + k
C = x² – 240x + k
k is the overhaul cost
⇒ k = 10,000
So C = x² – 240x + 10,000
When x = 300 hours, total cost is
C = (300)² – 240(300) + 10,000
⇒ C = 90,000 – 72000 + 10,000
⇒ C = 28,000
So the total cost of the engine run for 300 hours after the overhaul is ₹ 28,000.

Question 2.
Elasticity of a function \(\frac{\mathbf{E}_{y}}{\mathbf{E}_{x}}\) is given by \(\frac{\mathbf{E}_{y}}{\mathbf{E}_{x}}=\frac{-7 x}{(1-2 x)(2+3 x)}\) Find the function when x = 2, y = \(\frac{3}{8}\)
Solution:

Question 3.
The elasticity of demand with respect to price for a commodity is given by \(\frac{(4-x)}{x}\) where p is the price when demand is x. Find the demand function when the price is 4 and the demand is 2. Also, find the revenue function.
Solution:

Question 4.
A company receives a shipment of 500 scooters every 30 days. From experience, it is known that the inventory on hand is related to the number of days x. Since the shipment, I(x) = 500 – 0.03x², the daily holding cost per scooter is ₹0.3. Determine the total cost for maintaining inventory for 30 days.
Solution:
Here inventory I(x) = 500 – 0.03x²
Unit holding cost C₁ = ₹0.3
T = 30 days
So total inventory carrying cost

Hence the total cost for maintaining inventory for 30 days is ₹ 4,419.

Question 5.
An account fetches interest at the rate of 5% per annum compounded continuously. An individual deposits ₹ 1,000 each year in his account. How much will be in the account after 5 years. (e^0.25 = 1.284)
Solution:
p = 1000, N = 5, r = 5% = 0.05

After 5 years ₹ 5680 will be in the account

Question 6.
The marginal cost function of a product is given by \(\frac{d c}{d x}\) = 100 – 10x + 0.1x² where x is the output. Obtain the total and the average cost function of the firm under the assumption, that its fixed cost is ₹ 500.
Solution:
Given MC = \(\frac{d c}{d x}\) = 100 – 10x + 0.1x²
C = ∫ MC dx + k
C = ∫ (100 – 10x + 0.1x²) dx + k
C = 100x – 5x² + \(\frac{0.1 x^{3}}{3}\) + k
The fixed cost is 500 ⇒ k = 500
Hence total cost function = 100x – 5x² + \(\frac{0.1 x^{3}}{3}\) + 500
Average cost function AC = \(\frac{c}{x}\)
\(=100-5 x+\frac{x^{2}}{30}+\frac{500}{x}\)

Question 7.
The marginal cost function is MC = 300 \(x^{\frac{2}{5}}\) and fixed cost is zero. Find out the total cost and average cost functions.
Solution:

Question 8.
If the marginal cost function of x units of output is \(\frac{a}{\sqrt{a x+b}}\) and if the cost of output is zero. Find the total cost as a function of x.
Solution:

Question 9.
Determine the cost of producing 200 air conditioners if the marginal cost (is per unit) is C'(x) = \(\left(\frac{x^{2}}{200}+4\right)\)
Solution:

Question 10.
The marginal revenue (in thousands of Rupees) functions for a particular commodity is 5 + 3e^-0.03x where x denotes the number of units sold. Determine the total revenue from the sale of 100 units. (Given e^-3 = 0.05 approximately)
Solution:
Given, marginal Revenue R'(x) = 5 + 3e^-0.03x
Total revenue from the sale of 100 units is

Total revenue = 595 × 1000 = ₹ 5,95,000

Question 11.
If the marginal revenue function for a commodity is MR = 9 – 4x². Find the demand function.
Solution:
Given, marginal Revenue function MR = 9 – 4x²
Revenue function, R = ∫(MR) dx + k

Question 12.
Given the marginal revenue function \(\frac{4}{(2 x+3)^{2}}-1\), show that the average revenue function is P = \(\frac{4}{6 x+9}-1\)
Solution:

Question 13.
A firm’s marginal revenue function is MR = 20 \(e^{\frac{-x}{10}}\left(1-\frac{x}{10}\right)\). Find the corresponding demand function.
Solution:

Question 14.
The marginal cost of production of a firm is given by C'(x) = 5 + 0.13x, the marginal revenue is given by R'(x) = 18 and the fixed cost is ₹ 120. Find the profit function.
Solution:
MC = C'(x) = 5 + 0.13x
C(x) = ∫C'(x) dx + k₁
= ∫(5 + 0.13x) dx + k₁
= 5x + \(\frac{0.13}{2} x^{2}\) + k₁
When quantity produced is zero, fixed cost is 120
(i.e) When x = 0, C = 120 ⇒ k₁ = 120
Cost function is 5x + 0.065x² + 120
Now given MR = R'(x) = 18
R(x) = ∫18 dx + k₂ = 18x + k₂
When x = 0, R = 0 ⇒ k₂ = 0
Revenue = 18x
Profit P = Total Revenue – Total cost = 18x – (5x + 0.065x² + 120)
Profit function = 13x – 0.065x² – 120

Question 15.
If the marginal revenue function is R'(x) = 1500 – 4x – 3x². Find the revenue function and average revenue function.
Solution:
Given marginal revenue function
MR = R’(x)= 1500 – 4x – 3x²
Revenue function R(x) = ∫R'(x) dx + c
R = ∫(1500 – 4x – 3x²) dx + c
R = 1500x – 2x² – x³ + c
When x = 0, R = 0 ⇒ c = 0
So R = 1500x – 2x² – x³
Average revenue function P = \(\frac{R}{x}\) ⇒ 1500 – 2x – x²

Question 16.
Find the revenue function and the demand function if the marginal revenue for x units is MR = 10 + 3x – x²
Solution:

Question 17.
The marginal cost function of a commodity is given by MC = \(\frac{14000}{\sqrt{7 x+4}}\) and the fixed cost is ₹ 18,000. Find the total cost and average cost.
Solution:

Question 18.
If the marginal cost (MC) of production of the company is directly proportional to the number of units (x) produced, then find the total cost function, when the fixed cost is ₹ 5,000 and the cost of producing 50 units is ₹ 5,625.
Solution:
Given that the marginal cost MC is directly proportional to the number of units x.
That is, MC ∝ x
MC = kx, where k is the constant of proportionality
Total cost C = ∫(MC) dx + c₁

Question 19.
If MR = 20 – 5x + 3x²
Solution:

Question 20.
If MR = 14 – 6x + 9x², find the demand function.
Solution:
MR = 14 – 6x + 9x²
R = ∫(14 – 6x + 9x²) dx + k
= 14x – 3x² + 3x³ + k
Since R = 0, when x = 0, k = 0
So revenue function R = 14x – 3x² + 3x³
Demand function P = \(\frac{R}{x}\) = 14 – 3x + 3x²

Describe the friendship between Khushwant Singh and grandmother.
Answer:
Khushwant Singh’s grandmother was closely involved in bringing him up when the author lived with her in the village during his early life. She used to wake him up early in the morning. While bathing and dressing him, she sang her prayers. She hoped that the young boy would learn it by heart. She then gave him breakfast – a stale chapatti with butter and sugar.

Then they would go together to the temple school. While the author learnt his lessons, the grandmother would read holy books. They returned home together. She used to verify what the author learnt in school everyday. A turning point came in their friendship when his parents called them to the city. Although they shared a room, she could not help him much. She hated music, Science and Western education. The common link of their friendship was gradually snapped.

Why was Mary Kom named the “Queen of Boxing” and “Magnificent Mary”?
Answer:
After Mary Kom’s first silver medal in Pennsylvania in 2001, there was no looking back. Her medal haul continued even after her marriage putting an end to the speculation of family and friends that her marriage may slow down her career progression. She retained the world title in the third World Women’s Boxing Championship at Podolsk in Russia in 2005. She won her fourth gold also in 2006. She had won several golds for India from 2001 to 2004.

She had won all the Senior Women’s Boxing Championships, Second Women’s Championship (2002), Second Asian Women’s Boxing Championship at Hisar (2003) and the Witch Cup Boxing Championship at Paes, Hungary. There were a number of other International World Championships in Taiwan, Vietnam, Denmark and so on. But it was retaining her World title in 2006 by defeating Steluta Duta of Romania which was considered as Mary Kom’s greatest achievement in life. With this hat-trick of World Championship wins, the media christened her, “Queen of Boxing” and “Magnificent Mary”.

Question 42.
How does the poet establish the victory of common sense over ego?
Answer:
The poet is sure of his limitations. He had only modest of physiques. He can’t imagine receiving blows in a boxer’s ring. He has seen zealous athletes playing so rough that they never consider the . feelings of fellow players. They are insensitive to the cracking wrist and snapping knees of fellow players. When his ego and prudence clashed, ego told him to seek glory in sports, but his prudence always ignored it. Thus common sense prevailed. He remained a cheerful life-time fan of successful athletes. He was contented as a spectator of all kinds of games and sports and world famous athletes.

What are the mysterious ways in which Macavity acts?
Answer:
Macavity is an elusive master criminal who leaves no evidence after he commits a crime. He baffles Scotland Yard police and the flying squad as he disappears before their arrival to the scene of crime. He defies law of gravity and his powers of levitation make the fakir stare with wonder. Macavity loots the larder. He ransacks the jewel case. He is an elusive criminal who escapes from the spot of crime before the flying squad or Scotland Yard reach there.

He breaks every human law and laws of gravity. He breaks greenhouse glasses. He steals stealthily into the kitchen and empties milk. When an important treaty in the embassy is missing or when the admiralty loses some plans or drawings, the investigation terms conclude that it is the work of Macavity. But Macavity, as a wonder of wonders, would be miles away relaxing somewhere.

Question 43.
Write an essay of about 150 words by developing the following hints.
Miss Meadows-upset-remains gloomy-in class-taxes the students-sing sad-the girls sense her change-Basil-She thinks of the letter-called by headmistress-telegram- happy and returns to the class with vigour and good cheer.
Answer:
Miss Meadow was heart-broken. The letter written by Basil had pierced her heart and she was bleeding. Her hatred and anger became a knife and she carried it with her. Her icy cold response to Science Mistress demonstrates it. She is least bothered about the tender feelings of young children who look at her face all time for a friendly nod or smile of approval.

Her favourite pupil Mary Beazley is baffled at her treatment of the chrysanthemum she had brought with so much love. The choice of the song “A lament” perfectly jells well with her worst mood. She is in fact in her heart lamenting over the loss of love, trust and future hopes. She is unnecessarily severe with young children forcing them to redo the singing which drives them to despair, pain and tears they manage to stifle. After she receives the telegram from Basil apologizing for his insane letter, her mood changes to joy. She takes the chrysanthemum and keeps it close to her lips to conceal her blush.

She goads’the children to sing a song of joy congratulating someone for success. She persuades them to show warmth in their voices. Her warm and lively voice dominates the tremulous voices of the young ones. The young ones now realize that Miss Meadow who was in a wax earlier is now in her elements.

Jack and Jill- believe – things in installments— recently purchased – house – on easy installment – Aunt Jane – visited – preached – ease and comfort of buying – in installments the couple – first baby in installment.
Answer:
The Never Never Nest is a comic one-act play about a young couple who make full use of the buy-now-pay-later system. Jack and Jill were a young married couple who had a small baby. One day Aunt Jane visited them and was surprised to find that even though Jack’s salary was not high, they lived in a beautiful house with all comforts.

She began to wonder whether, as a wedding gift she had given them 2000 pounds instead of 20 pounds. Otherwise how did Jack and Jill buy all these things? Then Jane understood that though they had everything, nothing really belonged to them. They bought everything on instalments. Only a steering wheel of the car, a wheel and two cylinders had been paid for. The total amount to be paid towards instalments was more than their earnings. Aunt Jane was shocked at the way Jack and Jill ran their family.

Before she left, she gave ten pounds to Jill and told them to make at least one article completely theirs, using that money. While Jack went with aunt Jane to the bus stop, Jill sent the money to Dr. Martin. Jack came back and said that he wanted to pay two months instalments on the car using the aunt’s gift. But Jill said that by paying this money to Dr. Martin, their baby would become completely theirs.

Question 44.
Write a summary or Make notes of the following passage.
Answer:
The tests of life are its plus factors. Overcoming illness and suffering is a plus factor for it moulds character. Steel is iron plus fire, soil is rock plus heat. So lets include the plus factor in our lives.

Sometimes the plus factor is more readily seen by the simple-hearted. Often it takes a third eye or a change in focus, to see the plus factor. Walking along the corridors of a hospital recently where patients were struggling with fear of pain and tests, I was perturbed. What gave me a fresh perspective were the sayings put up everywhere, intended to uplift. One saying made me conscious of the beauty of the universe in the midst of pain, suffering and struggle. The other saying assured me that God was with me when I was in deep water and that no troubles would overwhelm me.

The import of those sayings also made me aware of the nether springs that flow into people’s lives when they touch rock bottom or are lonely or guilt ridden. The nether springs make recovery possible, and they bring peace and patience in the midst of negative forces.

The forces of death and destruction are not so much physical as they are psychic and psychological. When malice, hatred and hard-heartedness prevail, they get channeled as forces of destruction. Where openness, peace and good-heartedness prevail, the forces of life gush forth to regenerate hope and joy. The life force is triumphant when love overcomes fear. Both fear and love are deep mysteries, but the effect of love is to build, whereas fear tends to destroy. Love is generally the plus factor that helps build character. It creates bonds and its reach is infinite.

It is true there is no shortage of destructive elements – forces and people who seek to destroy others and in the process destroy themselves – but at the same time there are signs of love and life everywhere that are constantly enabling us to overcome setbacks. So lets not look at gloom and doom – let us seek positivity and happiness. For it is when you seek that you will find what is waiting to be discovered.

Question 45.
You are Vineeth, Ramakrishna Road, Mylapore, Chennai. Write a letter to prestigious newspaper highlighting the need to save water and raise the water table.
Answer:
From
Vineeth
Ramakrishna Road, Mylapore
Chennai

To
The Editor
Indian Express
Chennai
Respected Sir,
Sub: Need to save and harvest water.
Through the column of your prestigious newspaper, I want to highlight the urgent need to save and harvest water.

Water is the basic amenity for human beings, animals and birds. Globalisation of our economy has given a free rein to the multinationals. Bottling of water is a thriving business in India. The companies are minting money in the name of providing pure and clean water to people. Rivers are being sold: They are eyeing water supply in big cities. They play no role in conserving water. Water resources are facing a serious threat of depletion. Wells, hand- pumps and tube wells are sucked dry. If water table falls, farmers will not be able to cultivate crops. It will create chaotic conditions.

The government and public must understand the urgent need to save water. We should not waste a drop of water. Water harvesting must be done on a large scale in the rainy season. We must store water in lakes, tanks and ponds. Recycling of water is the need of the hour. Let us take urgent steps to meet the urgent situation. Act before it is too late and the situation becomes beyond redemption.

Thanking you
Yours faithfully,
Vineeth

Write an essay in about 150 words on ‘The Defects of Our Education System’.
Answer:
The Defects of Our Education System
The prime objective of our education system is to develop a child’s personality. It should train not only the mind, but also the body and soul. Unfortunately, our present education system fails to achieve these objectives. The present education system does not make a child creative. It makes him a crammer. A child or the pupil has to mug up nearly 200-300 pages a year to pass the examination. Students are not given any practical training. Moreover, the admission system has become the laughing stock of society.

The school authorities have a provision for interviews for the tiny tots who seek admission to pre-nursery. This is the height of absurdity. Our nation requires engineers, scientists, technicians and doctors who have understood the concepts clearly and are able to show their smartness in the work. An educated person should not only have bookish knowledge. He must have practical knowledge too. Unless a person has enough practical knowledge in his field he would be a failure in his profession leading to jeopardising many lives.

Question 47.
Read the following passage carefully and answer the questions that follow.
Answer:
Grounding, or Earthing, is a new-age therapy that is fast gaining ground. Its proponents argue that when the bare skin of our feet connects with the electric charge of the earth, we are ‘grounded’, that is to say, the free radicals creating havoc in our bodies are neutralized.
The result is emotional and physical health.

Modern lifestyle factors such as life in high-rise buildings, sleep on elevated cots (as different from beds spread on the floor) and the wearing of shoes with rubber soles have contributed to our lack of direct skin connection with the earth’s surface. Electrons from the earth may be the best source of antioxidants for our bodies and they have zero negative secondary effects, because our bodies have evolved over eons of physical contact with the ground. Our modern lifestyles have broken this natural connection with the ground and taken our immune system by surprise, depriving it of its primordial source of energy.

Research by Oschman, Chevalier, and Brown studied the effects of grounding on the immune system, inflammation, wound healing and treatment of autoimmune diseases. They concluded that disconnect from earth has an “important, insidious, and overlooked Contribution to physiological dysfunction and to the alarming global rise in non-communicable, inflammatory-related chronic diseases”. Chronic fatigue, injury, inflammation and autoimmune disorders may be the results of this disconnect.

The practice of grounding rests on the fact that we are bioelectrical beings living on an electrical planet. Our bodies operate electrically. Our cells transmit multiple frequencies that run our heart, immune system, muscles, and nervous system. Multiple positive effects can be created by a reconnection to the earth. These include decreased levels of inflammation and pain, reduced stress levels, improved circulation, and mood enhancement.
Questions.

1. Which new therapy is gaining currency?
2. How can emotional and physical health be gained naturally?
3. What has the habit of wearing rubber chappals prevented us from getting?
4. What would be the best source of anti-oxidants for humans?
5. What are the obvious harms due to man’s disconnection with earth?

Answer:

1. Grounding, or Earthing, is a new-age therapy that is fast gaining currency.
2. The practice of grounding rests on the fact that we are bioelectrical beings living on an electrical planet. When we connect with the earth, cells transmit multiple frequencies that run our heart, immune system, muscles, and nervous system. Multiple positive effects can be created by a reconnection to the earth.
3. The habit of wearing chappals has prevented from electrons from the earth entering our body.
4. Electrons from the earth may be the best source of antioxidants for our bodies and they have zero negative secondary effects.
5. Man’s disconnection from the earth has led to depriving the immune system of its primordial source of energy.

PART – III

III. Answer any seven of the following: [7 × 3 = 21]
(i) Explain any two of the following with Reference to the Context: [2 × 3 = 6]

Question 31.
While their ice-block-cold eyes Search behind my shadow
Answer:
Reference : These lines are from the poem, “Once upon a time” written by Gabriel Okara.

Context: The poet says these words while lamenting over the changes in the behaviour of modem people.

Explanation: The poet expresses the behaviour of people. The laugh is purely plastic, (i.e) lifeless. The eyes are devoid of emotions and hence described as “iceblock” (i.e) cold and hostile. They search behind the shadows means that ‘they’ are characterized by predatory or ulterior motives to exploit.

Question 32.
Athletes, I’ll drink to you,
Or eat with you,
Or anything except compete with you…
Answer:
Reference: These words are from the poem “Confessions of a Bom Spectator” written by Ogden Nash.

Context: The poet says these while contemplating the probability of swapping places with them.

Explanation: The poet has limp and bashful spirit which feeds on other people’s heroic deeds. The zealous players maim one another to win laurels. The thrill and excitement of all kinds of sports and games pleases the poet but he is wise enough to stay out and be a spectator because he has modest of physiques. He admits he would rather share a drink with them in a pub or dine with them in a restaurant. He is even ready to buy the most expensive tickets, as expensive as radium, to see them play the rough games but never compete with them.

Question 33.
To seek a gain we adore none:
We are proud and feel so tall.
Answer:
Reference: These lines are from the poem “Everest is not the Only Peak” written by Kulothungan.

Context: The poet uses these words praising ordinary people leading contented life.

Explanation: The simple folks do not stoop to underhand dealings to achieve their desired goals in life. The efforts made in reaching even the smallest positions in life,- if done with sincerity of purpose and deep devotion, is worthy of hearty appreciation. They are straight forward and derive their pride from their own integrity.

No one else raised the stake. The auctioneer rang the bell and the author realized with alarm how on earth he could ever raise that much money. He thought he could find a firing party to shoot him down. Death is better than public disgrace.

IV. Answer the following: [7 x 5 = 35]

Question 41.
Bill Bryson “ached to be suave”. Was he successful in his mission? List his “unsuave ways.
Answer:
Bill Bryson expresses his genuine desire to be “suave”. He would love just once in his life time to rise from the dinner table as if he had not experienced an “extremely localized seismic event, get into a car without leaving 14 inch coat outride, wear light-coloured trousers without ever discovering” at the end of the day that he had at various times and places sat on chewing gum, ice-cream cough syrup and motor oil. No, Bill Bryson was not successful in his mission.

Twice he spilled his drinks on a sweet nun who happened to sit next to him. He tried to show off his wisdom to another attractive lady. As usual, he was sucking his pen. His shirt, teeth and gum carried the unscrubbable navy blue stain for many days. He always did “liquid mischief’. His clumsy behaviour in the aeroplane made the saintly nun use abusive language. To avoid unsuave ways, he gave up air-travel with his family members. His wife and children supported him yet failed to refine his manners.

How do Universities mould students apart from imparting academic education to them?
Answer:
Universities mould students by providing various opportunities to develop their soft skills and to develop values which would contribute to the process of nation building. They enable graduates to develop patience and perseverance. They help them develop faith in their own inherent ability to shoulder responsibilities. They are oriented to become citizens of democracy and repay to the society quality services which would reform the lives of the poor people.

They develop true spirit of democracy among young graduates. They enable appreciation of others point of view. The graduates are also provided opportunities to adjust with difference through amicable discussions. The universities, apart from imparting education mould the student’s character and personality too.

Question 42.
The poem does not focus on the destination but the journey towards it. Discuss.
Answer:
The poet discusses the merits of efforts, duty and devotion and values of honesty, uprightness and service-mindedness. He does not have any special appreciation to those who reach great peaks like Himalayas. He appreciates the process, the journey and not the destination. When the whole world has a perspective of seeking glory using any foul method or underhand dealing, the poet differs from it.

For him the means is more important than the end. However modest may be one’s position is, it is adorable if attained by competence and merit. Pride is not in heights one reaches but in a life that knows no bending or kneeling. The poet respects one who does not stoop as a king. Thus the poet pays importance to the journey of life not the destination.

[OR]

According to the poet what contributes most to the injuries sustained by the athletes?
Answer:
According to the poet, zealous athletes play so rough that they do not even consider one another’s feelings in their dealings with other players. The players are mostly goaded by prize money or glory from the media’s light on them. They maim each other as they romp. Cracking vertebrae and spines don’t stop the rough players. Most of the players don’t have sportsmanship.

They don’t treat success and failure equally. In order to get the light of fame on their face, they are ready to permanently disable a rival player too. The crazy desire for championship titles and the light of fame on them leads them to ignore swollen eyes, snapping of knee joints or cracking of wrists. In short, the poet believes the apathy of zealous players and obvious indifference to the pain and debilitating injury contribute most to the injuries sustained by athletes.

Question 43.
Write an essay of about 150 words by developing the following hints.
Miss Meadows – upset – remains gloomy – in class – taxes the students – sing sad – the girls sense her change – Basil – She thinks of the letter – called by headmistress – telegram – happy and returns to the class with vigour and good cheer.
Answer:
The Singing Lesson, written by Katherine Mansfield, is all about a surprising day of a music teacher’s life. Miss Meadows, a music teacher, receives a letter from her finance which states quite plainly that Basil, her finance, isn’t ready to marry her and feels that the marriage would fill him with disgust. Naturally she’s filled with despair, anger and sadness. Her usrfal calm and cheery demeanor turns gloomy and angry that day and this change doesn’t go unnoticed by her students. During the lesson she’s rather harsh with her students. She tells them that today they would be practising a lament.

Then she tells them that they must feel the despair, the pain and the sorrow in order to perform the piece perfectly. During the lesson she’s informed by another colleague that Basil, her finance, has sent a telegram for her. Her first thought is that Basil has committed suicide! Yes, you read that right. It’s because the school has a rule; telegram can be sent to the workers during working hours only in case of death or emergency situation.

But in the telegram Basil had asked her to ignore the first letter and that he had bought the hat-stand which they had been thinking of lately. In short, the marriage is happening. The content of the telegram definitely lights up her mood. She returns and continues her class, now practicing a cheerful song, singing with expressions, more loudly and cheerfully than any of her students.

The title – new trend of young middle – class couple – buying in easy installments – Jack and Jill, serious matter – with six pounds earning – installments were higher than income – playwright feels – couples would make a nest – but never settle or nest happily.
Answer:
The Never Never Nest is a comic one-act play about a young couple who make foil use of the buy-now-pay-later system. Jack and Jill were a young married couple who had a small baby. One day Aunt Jane visited them and was surprised to find that even though Jack’s salary was not high, they lived in a beautiful house with all comforts. She began to wonder whether, as a wedding gift she had given them 2000 pounds instead of 20 pounds.

Otherwise how did Jack and Jill buy all these things? Then Jane understood that though they had everything, nothing really belonged to them. They bought everything on installments. Only a steering wheel of the car, a wheel and two cylinders had been paid for. The total amount to be paid towards installments was more than their earnings. Aunt Jane was shocked at the way Jack and Jill ran their family. Before she left, she gave ten pounds to Jill and told them to make at least one article completely theirs, using that money.

While Jack went with aunt Jane to the bus stop, Jill sent the money to Dr. Martin. Jack came back and said that he wanted to pay two months installments on the car using the aunt’s gift. But Jill said that by paying this money to Dr. Martin, their baby would become completely theirs.

Question 44.
Write a summary or Make notes of the following passage.
Observe the eating habits of your dog. It does not eat, except when hungry. It does not drink, unless it is thirsty. It does not gorge itself. It stops eating when it has had enough. A dog also sets a perfect example of adaptability. If it is moved to a strange place, it is able to adapt itself to that place and to its thousand peculiarities without a murmur of complaint. It is able to learn and adapt to a new family’s ways and customs. It is quick and ready to please. Man, being accustomed to comfort and wealth will be lost if suddenly stripped of all he is accustomed to.

A dog also teaches us a thing or two about, unselfish love. When a dog knows death is approaching, it tries, with its last vestige of strength, to crawl away elsewhere to die, in order to burden its owners no more. A dog does things with all vigour. However, when there is nothing to do, it lies down and rests. It does not waste its strength and energy needlessly. Many working people are burning the candles at both ends. Many suffer nervous breakdowns due to stress. Perhaps, they should learn to rest like a dog does. A dog above all is truly man’s best friend.

Write an essay in about 150 words on ‘How will you protect the Earth from the evil of deforestation’.
Answer:
How will you protect the Earth from the evil of deforestation
Deforestation leaves wild animals and birds homeless. We, humans face a lot of undesirable environmental changes. The most threatening one is Global Warming. Deforestation affects seasonal cycles. We experience droughts or floods, long summer or winter, thus, deforestation affects seasonal cycles. One more harmful effect of deforestation is soil erosion. Thus, the harmful consequences of deforestation are manifold. Tropical rainforests are being felled substantially for the purpose of farming and human habitation.

Afforestation should be done in a large scale. This should be initiated by government and we all should actively participate and involve and most importantly act to protect mother nature. We should permit tribal people to use twigs and dry woods instead of felling trees for firewood. If we incentivize tree plantation in the fringes of the forests, the tribal community will earn some livelihood and at the same time protect the forests from greedy timber smugglers.
