Study the following pie-chart and the table and answer the questions based on them.

Proportion of Population of Seven Villages in 1997

If in 1998, the population of villages Y and V increase by 10% each and the percentage of population below poverty line remains unchanged for all the villages, then find the population of village V below poverty line in 1998, given that the population of village Y in 1997 was 30000.

If in 1998, the population of villages Y and V increase by 10% each and the percentage of population below poverty line remains unchanged for all the villages, then find the population of village V below poverty line in 1998, given that the population of village Y in 1997 was 30000.

A.

11250

B.

12760

C.

13140

D.

13780

Correct answer is B

Population of village Y in 1997 = 30000 (given).

Let the population of village V in 1997 be v.

Then, 15 : 10 = 30000 : v   =>   v = (30000 x 10)/15 = 20000

Now, population of village V in 1998 = 20000 + (10% of 20000) = 22000.

Therefore Population of village V below poverty line in 1998 = 58% of 22000 = 12760.
