    present age

    let the sons age be x

    then fathers age= 4x

    after 4years

    sons age= x+4

    fathers age = 4x+4

    but given after 4 years

    sons age = x+4

    fathers age = 3(x+4)

    4x+4 = 3(x+4)

    4x+4 = 3x+ 12

    4x-3x=12-4

    x=8

    4x= 4*8

      =32

    Therefore present age of son is 8 years and father  is 32 years
