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:
Answer: Option
Explanation:
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
x = 22.

Age difference will be 24.
And after 2 years father's age will be twice as son's age. So 14, 18, 20 will not be answer.

Guys.
Because both father and son ages are increasing. If father age increases two years so sons are will be increased.

But as per question the father will be twice old as his son so we need to double fathers age and not sons age.

@Alisha and Yash,
We assume that the present age of son be "x" that is 22. We don't subtract 2 from that.

Anyone please answer me,
They have asked present age of son right?
Then it must be (22-2) = 20.

Son age =x
Father age =(x+24)
After 2year
(X+24)+2=(x+2)2
X+26=2x+4
X=22 (solu:2x-x=x,26-4=22)
Father age =(x+24)
After 2year
(X+24)+2=(x+2)2
X+26=2x+4
X=22 (solu:2x-x=x,26-4=22)

Why can't we do like this:
(2+2x) =24.
2x = 24-2.
2x = 22.
x = 11.
So then twice will be 22.
(2+2x) =24.
2x = 24-2.
2x = 22.
x = 11.
So then twice will be 22.

After two years, father's age = after 2 years son age twice so;
(x+24) + 2 = 2(x+2) came.
(x+24) + 2 = 2(x+2) came.

Why we multiply 2 with sons age why not with fathers age because father age will be twice?

I agree with you @Yash.
The present age of the son should be 20.
If not please explain.
