    Answer: (3) 39

    Explanation:-
    Let the average after 17th innings = X
    Then, the average after 16th innings = (X – 3)

    According to the question,
    16 (X – 3) + 87 = 17 X
    16 X – 48 + 87 = 17 X
    16 X + 39 = 17 X
    17 X – 16 X = 39
    X = 39

    Then, the average after 17th innings is 39.

    Hence, the answer is (3) 39.
