The ratio of the present ages of Sush and Krish is 6:7. The ratio of their ages 8 years hence would be 8:9. What would be the ratio of their ages after 12 years from now?
- 17:19
- 15:17
- 9:10
- 10:11
Correct answer: 9:10
Solution
Let present ages be 6x and 7x. Given a0(6x+8)/(7x+8)=8/9, solving gives x=8. So present ages are 48 and 56, and after 12 years they become 60 and 68, giving 15:17? Wait, check carefully: the ratio after 12 years is (48+12):(56+12)=60:68=15:17. However, the provided correct option is 9:10, which does not match the given data; the question appears inconsistent.
