Find the population of village S if the population of village X below poverty line in 1997 is 12160.

[A]. 18500
[B]. 20500
[C]. 22000
[D]. 26000

Answer: Option C

Explanation:

Let the population of village X be x.

Then, 38% of x = 12160   =>   x = 12160 x 100 = 32000.
38

Now, if s be the population of village S, then

16 : 11 = 32000 : s     =>     s = ( 11 x 3200 ) = 22000.
16

16:11 means percentage of X and percentage of S.

16% X =32000.
then 11% S be y.

y = (32000*11)/16 = 22000.

Instead, you can just calculate the total population and arrive at population simply. The question contains unnecessary information!

TOTAL POPULATION=200000 ;S=200000*11/100=22000.
