    Answer : Option D

    Explanation :


    Let the ratio constant be x
    Then the Present age of Arun, Sunil and Vivek would be 4x, 7x, 9x
    Age before eight years:
    4x-8, 7x-8, 9x-8
    According to question
    4x-8 + 7x-8 + 9x-8 = 56
    20x = 80
    x= 80/20
    x= 4
    Then their present is 4×4 = 16; 7×4= 28 and 9×4= 36 respectively.
