A man is 41 years old and his son is 9 years old. In how many years will the father be three times as old as the son?
Answer: 7 years
Explanation
Let x be the number of years in the future. Then:
Father’s age = 41 + x, Son’s age = 9 + x
Set up the equation: 41 + x = 3(9 + x)
→ 41 + x = 27 + 3x → 14 = 2x → x = 7 years.
