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.

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)

We got finally son's age as 22 year's,but in the problem they have mentioned only after two years father age will be twice as son's age so we have added 2 years both the side .. which is
(x + 24) + 2 = 2(x + 2)
So wen we get the answer we should subtract 2 years so tat we will be getting the present age ......... some body please clarify ma doubt ... :)
(x + 24) + 2 = 2(x + 2)

@vaishali.
The question its self saying that "In two years, his age will be twice the age of his son. " so we are adding "+2" on both sides means on fathers age and sons age. Ok I hope you understand.

Did not understood please explain why we add 2 for fathers age and multiply two for son's age in the equation: (X+24) +2= (x+2) 2.

Son age=x
Father age=x+24
After 2 years father age will be twice than son age
There fore x+24+2=26+x---------->1
Son age after 2yrs (x+2)2------->2
Sub 1 n 2
x+26=4+2x
2x-x=26-4
x=22
Father age=x+24
After 2 years father age will be twice than son age
There fore x+24+2=26+x---------->1
Son age after 2yrs (x+2)2------->2
Sub 1 n 2
x+26=4+2x
2x-x=26-4
x=22

In question it is clearly said that man's age will be twice the age of his son. So we have added 2 on both sides i.e. X+24+2 and X+2, where we have multipied by 2 on son's age to make equation equal. Have you clear friends ?

What's wrong with This method....
Let x be present age of man and y be present age of son.
Now,
Man is 24 years older than his son.So,
x = y + 24......(1)
Again acc to Question after two years he will be twice his sons age
x+2 = 2y......(2)
Solving eq (1) and (2)
y = 26
