1. 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.

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 = 20000. 15 Now, population of village V in 1998 = 20000 + (10% of 20000) = 22000. Population of village V below poverty line in 1998 = 58% of 22000 = 12760.
