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

A 14

B 19

C 38

D 40

E None of these

Correct Answer: Option A

Let son’s present age be X years. Then, (38 – X) = X
2X = 38
X = 19
Son’s age 5 years back = (19 – 5) years = 14 years
