Question

At present sum of ages of a father and son is 60. What will be the age after 15 years

Answer 1

The present sum of ages of father and son is 60

The age after fifteen years = we should add 15 for both father and the son because their both age will increase

So ,15+15 =30

The age after 15 years is 60+30=90

Hence it is 90 years old
