- 13 years
- 15 years
- 18 years
- 20 years

**Answer: (1) 13 years**

**Explanation:-**

Let be the present of the son = X years

Then, 36 – X = X

X + X = 36

2X = 36

X = 36/2 = 18

So, the present age of the son is 18 years.

5 years ago son’s age = 18 – 5 = 13 years

Hence, the answer is (1) 13 years.
