Table Charts Questions & Answers

The following table gives the percentage distribution of population of five states, P, Q, R, S and T on the basis of poverty line and also on the basis of sex.

If the population of males below poverty line for State Q is 2.4 million and that for State T is 6 million, then the total populations of States Q and T are in the ratio?

1:3

2:5

3:7

4:9

View answer & explanation

Correct answer is B

For State Q:

Male population below poverty line = 2.4 million.

Let the female population below poverty line be x million.

Then, 3 : 5 = 2.4 : x => x = (5 x 2.4)/3 = 4

Therefore Total population below poverty line = (2.4 + 4) = 6.4 million.

If N_q be the total population of State Q, then,

25% of N_q = 6.4 million => N_q = ( (6.4 x 100)/25 ) million = 25.6 million.

For State T:

Male population below poverty line = 6 million.

Let the female population below poverty line be y million.

Then, 5 : 3 = 6 : y => y = (3 x 6)/5 = 3.6

Therefore Total population below poverty line = (6 + 3.6) = 9.6 million.

If N_t be the total population of State T, then,

15% of N_t = 9.6 million => N_t = ( (9.6 x 100)/15 ) million = 64 million.

Thus, Required ratio = N_q/N_t = 25.6/64 = 0.4 = 2.5

The following table gives the percentage distribution of population of five states, P, Q, R, S and T on the basis of poverty line and also on the basis of sex.

What will be the male population above poverty line for State P if the female population below poverty line for State P is 2.1 million?

2.1 million

2.3 million

2.7 million

3.3 million

View answer & explanation

Correct answer is D

Female population below poverty line for State P = 2.1 million

Let the male population below poverty line for State P be x million.

Then, 5 : 6 = x : 21 => x = (2.1 x 5)/6 = 1.75

Therefore Population below poverty line for State P = (2.1 + 1.75) million = 3.85 million.

Let the population above poverty line for State P be y million.

Since, 35% of the total population of State P is below poverty line, therefore, 65% of the total population of State P is above poverty line i.e., the ratio of population below poverty line to that above poverty line for State P is 35 : 65.

Therefore 35 : 65 = 3.85 : y => y = (65 x 3.85)/35 = 7.15

Therefore Population above poverty line for State P = 7.15 million and so, male population above poverty line for State P

= ( 6/13 x 7.15 ) million

= 3.3 million

The following table gives the percentage distribution of population of five states, P, Q, R, S and T on the basis of poverty line and also on the basis of sex.

What will be the number of females above the poverty line in the State S if it is known that the population of State S is 7 million?

3 million

2.43 million

1.33 million

5.7 million

View answer & explanation

Correct answer is B

Total population of State S = 7 million.

Therefore Population above poverty line

= [(100 - 19)% of 7] million

= (81% of 7) million

= 5.67 million.

And so, the number of females above poverty line in State S

= ( 3/7 x 5.67 ) million

= 2.43 million.

The following table gives the percentage distribution of population of five states, P, Q, R, S and T on the basis of poverty line and also on the basis of sex.

If the male population above poverty line for State R is 1.9 million, then the total population of State R is?

4.5 million

4.85 million

5.35 million

6.25 million

View answer & explanation

Correct answer is D

Let the total population of State R be x million.

Then, population of State R above poverty line

= [(100 - 24)% of x] million

= ( 76/100 x x ) million

And so, male population of State R above poverty line

= [ 2/5 x ( 76/100 x x ) ] million

But, it is given that male population of State R above poverty line= 1.9 million.

Therefore 2/5 x ( 76/100 x x ) = 1.9 => x = (5 x 100 x 1.9)/76 x 2 = 6.25

Therefore Total population of State R = 6.25 million.
