# What will be the Present Age of A? If

The ratio of the ages of A and B at present is 3:1. Four years earlier the ratio was 4:1. The present age of A is.

- 40 years
- 32 years
- 36 years
- 48 years

**Answer: (3) 36 years**

**Explanation:-**

Let be the present age of A is 3X years and age of B is X years.

According to the question,

(3X – 4)/(X – 4 ) = 4/1

by cross multiplication,

3X – 4 = 4X – 16

X = 16 – 4

X = 12

Thus, the age of A is 3X = 3 x 12 = 36 years and the age of B is 12 years.

Hence, the answer is (3) 36 years.
