A man is 24 years older than his son. In two years, his age will be twice the age of his son. The present age of his son is

A 20

B 21

C 22

D 23

Correct Answer: Option C

Let the son's present age be x years. Then, man's present age = (x + 24) years
=> (x + 24) + 2 = 2(x + 2)
=> x + 26 = 2x + 4
So, x = 22
