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.

In this question people solve this problem by taking x as a 2 year back when father (x) is 24 year more then son (y).
x = y+24.
After two years.
x+2 = 2(y+2) -----------equation 1.
Put x value in equation 1.
y+24+2 = 2y+4.
y = 22.
Why value is 2 year previous is 22?
So present age of son is 24.
x = y+24.
After two years.
x+2 = 2(y+2) -----------equation 1.
Put x value in equation 1.
y+24+2 = 2y+4.
y = 22.
Why value is 2 year previous is 22?
So present age of son is 24.

I agree with you @Yash.

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.
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.

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

@All.
As some people said 22-2 =20 is answer.
I would say that better to check the options in this case if 20 is the answer after 2 years he will be 22 and his father will be 46 which is not twice relation so In this way you can verify your answer.
