1. Answer:

   let the present age of son is x years

   so present age of father is 4x years

   after 5 years son will be( x+5 )years and father will be (4x+5 )years

   here,

   4x+5=3(x+5)

   => 4x+5=3x+15

   => 4x-3x=15-5

   => x=10

   so, present age of son is 10 years and present age of father is 4×10years=40years
