Village % Population Below Poverty Line
X38
Y52
Z42
R51
S49
T46
V58

1. 

If the population of village R in 1997 is 32000, then what will be the population of village Y below poverty line in that year?

[A]. 14100
[B]. 15600
[C]. 16500
[D]. 17000

Answer: Option B

Explanation:

Population of village R = 32000 (given).

Let the population of village Y be y.

Then, 16 : 15 = 32000 : y     => y = ( 15 x 32000 ) = 30000.
16

Therefore Population of village Y below poverty line = 52% of 30000 = 15600.

Here the given population is 32000 for Village R.

From the pie chart it clearly mentioned the % of Village R is 16% of the total population, since we do not know the total population let we take it as "X".

So now ; X + 16% = 32000.

X= 32000*100/16 which is 2,Lkhs , So now the total Population was derived as 2,Lkh , For Village Y (Given %) => 15.

So 2,00,000 * 15/100 = 30,000.


From this 30,000 we have to find for the poverty Line % (given in the table) as 52%.

So, 30,000*52/100 = 15600.

Why does it have to be village Y?

How to get 15% of population?

How can you compare R and Y villages population?

Shabbaz said: (Aug 10, 2017)  
It can be calculated as R=16% = 32000.
::Y=15%= So, 15% of 32000 = 30000,
52% is below poverty line for Y= 52% of 15%=7.8%,
so, 30000*7.8/15 = 15600.
