At the end of the month, he sold all his shares and realised 25% profit. On Feb 1, he reinvested the entire amount in shares which he sold at the end of the month at a loss of 20%. Again, he invested the entire amount on Mar 1 in a new company. At the end of the month, he sold the new company to a friend and realised a profit of 20% in the process. He invested the entire amount in shares on Apr 1, which he sold at the end of the month for Rs. 1,08,000 incurring a loss of 10%.

1. What is the amount of retirement benefits received by Ghosh Babu?

a) Rs. 1,08,000

b) Rs. 1,25,000

c) Rs. 1,20,000

d) Rs. 1,00,000

2. The percentage profit received by Ghosh Babu between Jan 1 and Apr 30 is:

a) 8.00%

b) 15.00%

c) – 10.00%

d) None of these

3. The amount of loss incurred by Ghosh Babu based on his operation in Apr 1992 is:

a) Rs. 25,000

b) Rs. 12,000

c) Rs. 20,000

d) Rs. 8,000

4. The maximum amount invested by Ghosh Babu in any one month was in:

a) January

b) February

c) March

d) April

**Answers:**

1. d Let the amount received by Ghosh Babu in Dec. 1991 be Rs. x, as retirement benefits:

Therefore, investment in the month of Jan 1992 = 100

Profit of 25% at the end of Jan 1992.

Hence, investment in the month of Feb 1992 = 125

Loss of 20% at the end of Feb 1992

Hence, investment in the month of March 1992 = 100

Profit of 20% at the end of March 1992

Hence, investment in the month of April 1992 = 120

Loss of 10% at the end of April 1992

Therefore the amount left at the end of April 1992 = 108

Amount at the end of April 1002 = Rs. 1,08,000

Therefore, simply equating figures, he would have started with Rs 1,00,000

2. a % Profit between Jan 1 and Apr 30 = (1.08x – x/x) X 100

3. b Investment in the month of April = Rs. 1,20,000

Amount received at end of April = Rs. 1,08,000

Therefore, Loss = Rs. 12,000

4. b Maximum amount invested by Ghosh Babu is in the month of February = Rs. 1,25,000

**Solutions**

S1. Ans.(b)

Sol. 200 million = 20% of population

⇒ Population = 200 × 5 = 1000 million = 100 crore

S2. Ans.(b)

Sol. 2004 population = 1000 million

Population in 2008 or after 4 years = 560 × 2 = 1120 million

∴ Growth rate = (120 × 100)/(1000 × 4) = (12/4)% = 3% per annum simple growth rate.

S3. Ans.(c)

Sol. Hotel users in 2004 = 200 million

Hotel users in 2008 = 560 million

∴ Growth in percentage =(560 – 200)/200=360/200=180%

S4. Ans.(a)

Sol. Total revenue in 2004 = 50 billion

Total revenue in 2008 = 150 billion

∴ Growth in percentage =(150 – 50)/50×100=100/50=200%

S5. Ans.(d)

Sol. By 2008 half or 50% of the India population will be using hotels.

We do not have any information about 2007. Hence the data is inadequate.

S6. Ans.(b)

Sol. Born 100 ⇒ 10 die at infancy

90 ⇒ 10 die till age 5

80 ⇒ 2/3×1/2×80 go to school

∴ Who attend Std. V =80×1/3×0.4=10.66%

S7. Ans.(d)

Sol. Number of child labourers in India =(90×1/15)crore = 6 crore

S8. Ans.(a)

Sol. Out of 100 born, 20 die by the age of 5.

Number of child labourers in Orissa and Bihar =1/3×80≅27

S9. Ans.(d)

Sol. Since we do not know how many children reach Std X, the answer cannot be found. Hence, option (d).

S10. Ans.(d)

Sol. Since we do not know the exact population of Kerala, Orissa and Bihar, the answer cannot be found.

S11. Ans.(c)

Sol. Number of female literates =90×9/19×0.38=16.2 crore

Number of male literates =90×10/19×0.57 = 27 crore

∴ Total literates = 16.2 + 27 = 43.2 crore

S12. Ans.(c)

Sol. Total illiterates in India = 90 – 43.2 = 46.8 crore

∴ Number of illiterates in Orissa and Bihar =1/3×46.8 = 15.6 crore
