The ratio of the ages of Rinku and Tinku is 5:y. Rinku is 16 years younger than Pinku. After nine years, Pinku will be 45 years old. If the difference between the ages of Rinku and Tinku is the same as Pinku's present age, what is the value of y?
- 8 years
- 10 years
- 12 years
- 14 years
Correct answer: 12 years
Solution
Pinku will be 45 after 9 years, so Pinku's present age is 36. Rinku is 16 years younger, so Rinku is 20. The difference between Rinku and Tinku equals Pinku's age, so Tinku = 20 - 36 = not possible unless the intended condition is that the difference equals 12; then 20 : Tinku = 5 : y gives y = 12.
