Correct Answer: 7 years


Solution : Let the present age of the son be x years.

So, father's present age = 4x.

The age of the father 4 years ago was 8 times the age of his son

age of son 4 years ago = (x – 4) years.

age of father 4 years ago = (4x – 4) years.

⇒ 8 (x – 4) = 4x – 4

⇒ 8x – 32 = 4x – 4

⇒ 4x = 28

⇒ x = 7

So, the present age of the son is 7 years.

Hence, option second is correct.
