Father age is Always double of son's age so the answer is 38/2.

Let son age X and father age 38.
38(father age)-X (son age ) =X because father's age at the time of sons born (as per question ) =sons age i.e X.
Then 38-X = X.
38(father age)-X (son age ) =X because father's age at the time of sons born (as per question ) =sons age i.e X.
Then 38-X = X.

How did you formed (38-x) =x?

let's use ratio method.
Father : Son
38 : X
X : 0
Now do cross multiplication.
i.e. 2X=38 => X=19.
Five years back, the son's age is 19-5=14.
Father : Son
38 : X
X : 0
Now do cross multiplication.
i.e. 2X=38 => X=19.
Five years back, the son's age is 19-5=14.
