A father said to his son, "I was as old as you are at the present at the time of your birth". If the father's age is 38 years now, the son's age five years back was:

14 years 19 years 33 years 38 years

14 years

Let the son's present age be x years. Then, (38 - x) = x 2x = 38. x = 19 Son's age 5 years back =  (19 - 5) = 14 years.
