Eight years ago, a man was 5 times as old as his son. Eight years from now he will be 3 times as old as his son. Find the son's present age (in years).

Question

Accepted Answer

24. f - 8 = 5(s - 8) -> f - 5s = -32. f + 8 = 3(s + 8) -> f - 3s = 16. Subtracting: 2s = 48, s = 24 (then f = 88). Check: 8 years ago son 16, man 80 = 5x16; in 8 years son 32, man 96 = 3x32.
