1.  If in 1998, the population of village 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

Answer: Option B

Explanation:

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.
