The present age of the father and the son are in the ratio of 7 : 3. A...
⇒ 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
⇒ Father’s age = 7x = 7 x 6 = 42
⇒ Son’s age = 3x = 3 x 6 = 18
⇒ Sum of ages = 42 + 18
∴ Sum of ages = 60
⇒ 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
⇒ Father’s age = 7x = 7 x 6 = 42
⇒ Son’s age = 3x = 3 x 6 = 18
⇒ Sum of ages = 42 + 18
∴ Sum of ages = 60
