Directions to Solve 

The following table gives the percentage distribution of population of five states, P, 0, R, S and Ton the basis of poverty line and also on the basis of sex.

StatePercentage of Population below the poverty lineProportion of Males and Females
Below Poverty Line Above Poverty Line
M:FM:F
P355:66:7
Q253:54:5
R241:22:3
S193:24:3
T155:33:2

Question 1): If the male population above poverty line for State R is 1.9 million, then the total population of State R is? 

A. 4.5 million
B. 4.85 million
C. 5.35 million
D. 6.25 million 

Answer: Option D
Solution

Let the total polpulation of State R be x million.

Then, population of State R above poverty line

And so, male population of State R above poverty line

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

∴ Total population of State R = 6.25 million.

Question 2) 

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?
A. 3 million
B. 2.43 million
C. 1.33 million
D. 5.7 million 

Answer: Option B
Solution: Total population of State S = 7 million.
∴ Population above poverty line
= ((100 - 19}% of 71 million
= (81% of 7) million
= 5.67 million.
And so, the number of females above poverty line in State S

Question 3) 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? 

A. 2.1 million
B. 2.3 million
C. 2.7 million
D. 3.3 million 

Answer: Option D
Solution: Female population below poverty line for State P = 2.1 million
Let the male population below poverty line for State P be x million.

Let the population above poverty line for State P by 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 forState P is 35 : 65.

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