702 Two years ago, a father was 5 times as old as his son. Two years later (from now), his age will be 8 more than 3 times the son’s age. Find the father’s present age.
Explanation
- Let father = f, son = s
- (f-2) = 5(s-2) => f = 5s - 8
- (f+2) = 3(s+2) + 8 => f = 3s + 12
- Equating: 5s - 8 = 3s + 12
- s = 10, f = 42 years
