Question

father age is three times the sum of the ages of two children after 5 years his age will be twice the sum of the ages of two children find the present age of the father

Answer 1

Let the present sum of the sons’ ages be X years. Then, the father’s present age is 3X years.

5 years later, sum of the sons’ ages = X+2∗5X+2∗5years = (X+10)(X+10) years, and the father’s age would be (3X+5)(3X+5) years.

According to given, 3X+5=2(X+10)=>X=15.3X+5=2(X+10)=>X=15.

Thus, the father’s present age is (3 x 15) years = 45 years.
