  1. Answer:

    Given the ratio of present age of father and son is 4:1.

    Let their present age is 4x and x.

    Then 4 years ago their age was 4x−4 and x−4.

    Then according to the problem,

    x−4

    4x−4

    =

    2

    11

    or, 8x−8=11x−44

    or, 3x=36

    or, x=12.

    So present age of father and son is 48 years and 12 years respectively.
