⇒ Let the present age of father be 7x and age of son be 3x ⇒ Ages after 6 years ⇒ Father’s age = (7x + 6) ⇒ Age of Son = 3x + 6 ⇒ According to question ⇒ Ratio = (7x + 6) / (3x + 6) ⇒ 2 / 1 = (7x + 6) / (3x + 6) ⇒ 6x + 12 = 7x + 6 ⇒ x = 6 ⇒ x = 6 ⇒ Son’s age = 3x = 3 x 6 = 18 ⇒ Sum of ages = 42 + 18 ∴ Sum of ages = 60
