At present, the age of the father is 5 times that of the age of his son. After 10 years, the father’s age would be 3 times that of his son. Find the present ages of the son and the father?
Let the present age of son = x yrs. Then, the present age of father = 5x yrs After 10 years, 3(x + 10) = 5x + 10 ⇒ 3x + 30 = 5x + 10 ⇒ x = 10 yrs ∴ Present age of son = 10 yrs & the present age of father = 50 yrs.
