Question 759937: the sum of the ages of a father and son is 85 years. five years ago, the father was exactly four times as old as his son. the present age of the father is? Answer by sachi(548) (Show Source):
You can put this solution on YOUR website! the sum of the ages of a father and son is 85 years.
let the age of father is x
so the son's age=85-x
five years ago,
the age of father was=x-5
the son's age=85-x-5=80-x
APQ the father was exactly four times as old as his son.
x-5 =4(80-x)=320-4x
or 5x=325
or x=the present age of the father=325/5=65
