Answer 1

let present age of sahil is 'x'

   his mother age is '3x'

after five years

                       sahil's age is 'x+5'

                        his mother's age is '3x+5'

according to problem,                                      

                             given sum of their ages after five years is 66

                          ⇒(x+5)+(3x+5)=66

                             4x+10=66

                            4x=66-10

                            4x=56

                               x=56/4

                            x=14

sahil's age is  x=14=14 years

 sahil's mother age is 3x=3(14)=  42=42years
