Problema Solution
The age of a father now is four times that of his son. In ten years time, the father will be three times as old as his son. Find the present age of the father
Answer provided by our tutors
f=4s
f+10 = 3(s+10) where f and s are ages of father and son respectively.
4s+10 = 3s+30
s = 20
f = 80
Hence, father;s age = 80
son's age = 20
