Question

the sum of age of father and his son is 60 years if the age of son is 20 years find the age of father

Answer 1

Let the present ages of son and father be x and (60 -x) years respectively.

Then, (60 - x) - 6 = 5(x - 6)

⇒ 54 - x = 5x - 30

⇒ 6x = 84

⇒ x = 14.

∴ Son's age after 6 years = (x+ 6) = 20 years.
