    Answer:  (4) 400

    Explanation:-
    Let the maximum marks in the examination is X.

    According to the question,
    X x 30/100 – 12 = X x 40/100 + 28
    3 X/10 – 12 = 4 X/10 + 28
    4 X / 10 – 3 X/10 = – 12 – 28
    X/10 = – 40
    X = – 40 x 10
    X = 400              (Maximum Marks is never in negative)

    Then, the examination marks in the examination is 400.

    Hence, the answer is (4) 400.
