Question

A father is 30 year older than his son in 12 year the man will be three times as older as his son find the present age of the Son​

Answer 1

Let f = father's present age and s = son's present age.

f = s + 30

f + 12 = 3(s + 12)

s + 30 + 12 = 3s + 36

s + 42 = 3s + 36

2s = 6, so s = 3 and f = 33
