# What is the present age of his son?

The average age of man and his son is 28 years. Six years hence the ratio of their age becomes 12:5. What is the present age of his son?

- 12 years
- 14 years
- 15 years
- None of these

**Answer: (2) 14 years**

**Explanation:-**

The average of man and his son = 28 years

Then, the sum of the age of a man and his son = 2 x 28

= 56 years

Six years hence the sum of their ages = 56 + 2 x 6

= 56 + 12 = 68 years

Six years hence the ratio of their age becomes 12: 5

Then, the age of his son = 68 x 5/17

= 4 x 5

= 20 years

So, the present age of his son = 20 – 6

= 14 years

Hence, the correct answer is option (2) 14 years.
