The ratio of population of village T below poverty line to that of village Z below poverty line in 1997 is:

11 : 23

13 : 11

23 : 11

11 : 13

Answer : Option C

Explanation :

Let N be the total population of all the seven villages.

Then, population of village T below poverty line = 46% of (21% of N)

and Population of villages Z below the poverty line = 42% of (11% of N)

Required ratio = \(\frac {\text{46% of (21% of N)}} {\text{42% 0f (11 % 0f N)}} \) = \(\frac { 46 *21} { 42*11 } \) = 23/11
