Answer 2

Answer:

Present age of his son = 8 years .

Present age of the man = 32 years.

Step-by-step explanation:

Given :

A man is 4 times as old as his son.

To Find :

Their present ages.

Solution :

The present age of his son as -  x .

∴ The present age as - 4x

According to the Question,

After 16 years, the man will be twice his son.

So,

⇒ 4x + 16 = 2x + 32

⇒ 4x - 2x = 32 - 16

⇒ 2x = 16

⇒ x = $\dfrac{16}{2}$

⇒ x = 8 years.

Hence,

The present age of his son = x = 8 years

The present age of the man = 4x = 4 × 8 = 32 years
