A man has 2 daughters and 1 Son. The sum of 2 daughter and 1 Son is equal to age of father. In the 15 years, the sum of ages of his children will be one and half times their father's age then. What is the father age now?

Answer 1

Let the age of daughter and son be x and father be y.
x=y
x+15=3y/2
2x+30=3y
y=30, As x=y

The present age of father is 30.
