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

Proportion of Population of Seven Villages in 1997

If in 1998, the population of villages Y and V increase by 10% each and the percentage of population below poverty line remains unchanged for all the villages, then find the population of village V below poverty line in 1998, given that the population of village Y in 1997 was 30000.

A.

11250

B.

12760

C.

13140

D.

13780

Correct answer is B

Population of village Y in 1997 = 30000 (given).

Let the population of village V in 1997 be v.

Then, 15 : 10 = 30000 : v   =>   v = (30000 x 10)/15 = 20000

Now, population of village V in 1998 = 20000 + (10% of 20000) = 22000.

Therefore Population of village V below poverty line in 1998 = 58% of 22000 = 12760.

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

Proportion of Population of Seven Villages in 1997

Find the population of village S if the population of village X below poverty line in 1997 is 12160.

A.

18500

B.

20500

C.

22000

D.

26000

Correct answer is C

Let the population of village X be x.

Then, 38% of x = 12160   =>   x = (12160 x 100)/38 = 32000

Now, if s be the population of village S, then

16 : 11 = 32000 : s => s = ( (11 x 3200)/16 ) = 22000

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

Proportion of Population of Seven Villages in 1997

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

Correct answer is C

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

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

Proportion of Population of Seven Villages in 1997

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

Correct answer is B

Population of village R = 32000 (given).

Let the population of village Y be y.

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

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