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

A2:5 ✓ Correct
B2:7
C3:7
D4:9
Correct answer: (A) 2:5
Explanation

State B has 25 percent below the poverty line with a male to female ratio of 3 to 5.

So below-poverty males are 3 by 8, giving total B as 2.4 million divided by 0.25 times 3 by 8.

This makes the total population of State B equal to 25.6 million scaled to 1920 by 75 in working units.

State E has 15 percent below the line with a male to female ratio of 5 to 3, so males are 5 by 8.

Setting E below-poverty males equal to 6 million gives total E as 4800 by 75 in the same units.

The ratio of totals B to E is 1920 to 4800, which simplifies to 2 to 5.

Consistent unit handling lets the two totals be compared directly.
