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.

42 * 23 = 966.
42 * 11 = 462.

46*21=966/42*11=462.

But how are we getting answer 23/11?

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.

The value of 21 and 11 is the value of t and z from the above pie chart.
