Question

A father says to his son, "I was two years older than your present age when you were born." If the present age of the father is 36 years, then what was the age of his son 5 years ago?
1. 14 years
2. 12 years
3. 13 years
4. 16 years

Answer 1

Correct Answer - Option 2 : 12 years

Let; Age of son = x years

Than; Age of father when son was born  = (x + 2) years

Present age of father = x + (x + 2)

According to question;

Age of father = 36 years

So;

36 = x + (x + 2) 

2x + 2 = 36 

2x = 34

x = 17 years

Age of son = 17 years

5 years ago; 

The age of son = 17 - 5

= 12 years

Hence, "12 years" is the correct answer.
