Question

A man says to his son,"seven years ago i was seven times as old as you were, and three years hence I shall be three times as old as you" Find their age.

Answer 1

Answer. Let the past age of son = x Let the past age of father = 7x So, Present ages are x+5 and 7x+5 Future age of son = x+10 Future age of father = 7x+10 Given7x+10 = 3*(x+10) 7x+10 = 3x+30 7x-3x = 30-10 4x = 20 x = 20/4 x = 5 7x = 35 x+5 = 10 7x+5 = 40
