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
X38
Y52
Z42
R51
S49
T46
V58


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
Answer: Option
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 = 23/11.
42% of (11 % of N) 42 x 11

46*21/42*11.

Because 46/42 can be simplified into 23/21.
So, (23/21)*(21/11) = 23/11.

@Praveen

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