Data
Percentage of population of five states A–E below the poverty line, and Male:Female ratios below and above the poverty line.
| State | Below Poverty Line (%) | BPL M:F | APL M:F |
|---|---|---|---|
| A | 35% | 5:6 | 6:7 |
| B | 25% | 3:5 | 4:5 |
| C | 24% | 1:2 | 2:3 |
| D | 19% | 3:2 | 5:3 |
| E | 15% | 5:3 | 3:2 |
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 — State B has 25 percent below the poverty line with a male to female ratio of 3 to 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.
