Study the following pie-chart and the table and answer the questions based on them.

Proportion of Population of Seven Villages in 1997 Village % Population Below Poverty Line X 38 Y 52 Z 42 R 51 S 49 T 46 V 58

2.
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
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 = 46% of (21% of N) = 46 x 21 = 23/11. 42% of (11 % of N) 42 x 11

How this possible explain briefly please?

@Praveen

The total population has to consider for calculating the ratios.. And so 46*21 / 42*11 would give u the answer 23:11

Why they have taken N in this problem?

T = 21% ( in 21% of population 46% people are below powerty line).
Z= 11 % ( in 11% of T population, 42% people are below P line).
= 46% of 21/42% of 11.
= 46*21/42*11.
= 23/11.
