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

A. 11 : 23
B. 13 : 11
C. 23 : 11
D. 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)

Therefore Required ratio =46% of (21% of N)=46 x 21


42% of (11 % of N)42 x 11

= 23/11.
