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.

Here we assumed as the sons's present age as x. And through the problem we are finding the value of 'x'.that means present age.so no need to subtract that 2 years from 22. The son's present age is 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.

@Srikanth.
In another 2 years, son's age X will become X+2. So it is written as X+2.
Hence in question after two years father age will be twice of son's age so 2 (X+2).
In another 2 years, son's age X will become X+2. So it is written as X+2.
Hence in question after two years father age will be twice of son's age so 2 (X+2).

@Shravs.
Here, We are bringing all the x terms to one side and number to the other side so,
And another in our case you are multiplying 24 and x = 24x.
But in the case of the solution, there is + symbol in between 24 and x so, we should add it
We should not multiply it.

Hey it is very simple:
Age difference between father and son =24.
*( Age difference will be Same).
When the son reaches to age equals to difference means 24 then father's age will become double it happens after 2 years according to the question means;
Father age = 48.
Simply after 2 years,
Father =48, son =24.
We need the present age so subtract 2 from the above age;
Present age of F=46, S=22.
Age difference between father and son =24.

The answer is 20.
Suppose the son's present age is x, so father age is x+24.
After 2 years,
Father's age will be x+26 and son age will be x+2
So according to the condition as father's age is double of son's age then,
x+26=2(x+2),
x=22,
This is son's future age(i.e. After 2 years),
So the present age of son is 22-2=20.
