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.

Please solve this.
The present age of Geetha is 5 years more than the present age of his brother Mahesh. The present age of their father is twice the sum of their ages. At the time of Mahesh's birth, his father age was 8 times of the age of Geetha.
Find their present ages.

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.
