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:
14 years
18 years
20 years
22 years
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.

He said father's age will be twice not son's age.

If assume son age is x so father age will be 2x.

As we solved x = x+2 and x+2+24.

Please correct me?

A man is 24 years older than his son.

Let us take son's age as X. So, father's age will be X+24.

In two years, son's age X+2.

Father's age X+24+2 = X+26.

His (Father's) age will be twice the age of his son.

X+26 = 2(X+2) (Twice the age of his son. So twice Son's age).

X+26 = 2X+4.

22 = X.

By solving, X = 22.

Anyone can tell me why 2 is multiply with the son's age. Why not with the father age because father age will become the twice.

Please explain.

I agree with you @Yash.

The present age of the son should be 20.

If not please explain.

Let son's age = x,
Father is 24 years elder than the son, hence son's age = 24 + x,
In the question given that, after 2 years father age will be twice the age of the son.
So, (x + 24) + 2 = 2(x + 2) solve this.
The answer is 22.

@Alisha and Yash,

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