    Explanation:

    Let my age and son's age be x and y years.
    Given, x = 3y
    x + 5 = 5(y + 5)/2
    => 3y + 5 = 5(y + 5)/2 = (5y + 25)/2
    => 6y + 10 = 5y + 25
    => y = 15
    x = 3 X 15 = 45
    my age and son's age are 45 years and 15 years.

    Hence, option 3 is the correct answer.
