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)

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)

Hello Every body. I have one doubt.
In the question they said the father age is 24 years.
After coming 2 years his age will be twice of his son's age.
Finally we got sons age 22.
So now father age is twice of sons age as per question.
According to that now father age will be 44?

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

Like Mohan said,
So when we get the answer we should subtract 2 years so that we will be getting the present age. Some body please clarify my doubt.
So why it is not 20 ?
