RRB NTPC · Question 15

Directions: The following table shows the percentage distribution of population on the basis of poverty line and gender in five states M, N, O, P and Q.

State	Below Poverty Line Population %	Ratio of males (M) and females (F)
Below the poverty line	Above poverty line
M : F	M : F
M	40	7 : 6	8 : 7
N	30	3 : 2	6 : 5
O	26	1 : 1	4 : 3
P	17	1 : 2	4 : 5
Q	20	2 : 3	3 : 4

If the male population above the poverty line of state O is 1.7 million, then what will be the total population of state O? A. 4.02 million B. 5.36 million C. 5.63 million D. 4.92 million

Show answer & explanation

Answer: (D) A

Explanation

In state O, 100 − 26 = 74% are above the poverty line, and males are 4/7 of them: 74 × 4/7 ≈ 42.29% of the population. 1.7 million = 42.29%, so the total is 1.7/0.4229 ≈ 4.02 million.
