Answer:

40 + 4 + 4 = 48 years (present sum of ages of father and son)

Father : Son : Sum

   3      :   1    :    4

4 units = 48 years    

  1 unit = 48 years ÷ 4

            = 12 years

Father's present age = 3 × 12 years - 4 years

                                   = 36 - 4

                                   = 32 years

Son's present age = 12 years - 4 years

                              = 8 years
