Question

Three years back, a father was 24 years older than his son. At present the father is 5 times as old as the son. Write an equation to represent this situation.

Answer 1

Answer: 5s -3 = s -3 + 24 5s -3 = s + 21

Explanation:

Father f

Son s . present: f = 5s use this equation to substitute the equal value

3 years ago . f-3 = s-3 + 24

Substitute 5s for f in the second equation

5s -3 = s-3 + 24

works out as 5s -s = - 3 +3 + 24

4s = 24

4s/4 = 24/4

s = 6

The son's age is 6, The father is 30
