At present, P is three times Q's age, and after five years, P's age will be twice Q's age. What will P's age be after 10 years?

1. 20 years
2. 25 years
3. 22 years
4. 35 years

Correct answer: 25 years

Solution

Let Q's present age be \(x\). Then P's present age is \(3x\). After five years, \(3x+5=2(x+5)\), which gives \(x=5\) and P = 15. After 10 years, P will be \(15+10=25\) years old.
