A village has males and females in the ratio 4:3. After a few years, the male population increases by 15%, and the female population by 20%. What is the new ratio?

1. 23:18
2. 22:17
3. 24:19
4. 21:16

Correct answer: 23:18

Solution

Let males and females be 4x and 3x. After increase, males become 4x × 1.15 = 4.6x and females become 3x × 1.20 = 3.6x. The ratio 4.6:3.6 simplifies to 23:18.
