A mother is five times as old as her son. Ten years from now, she will be three times as old as her son. What is the son's present age?
- 5 years
- 10 years
- 15 years
- None of these
Explanation
Let the son's present age = x years.
Mother's age = 5x years.
After 10 years:
5x + 10 = 3(x + 10)
5x + 10 = 3x + 30
2x = 20 → x = 10
