    A 152 Correct Answer Incorrect Answer
    B 135 Correct Answer Incorrect Answer
    C 162 Correct Answer Incorrect Answer
    D 141 Correct Answer Incorrect Answer

    Solution

    ATQ,

    Assume total marks = 100x

    Pooja's marks = 0.42 × 100x = 42x

    Passing marks = 42x + 15

    Ramesh’s marks = 0.54 × 100x = 54x

    Passing marks = 54x - 21

    So, 42x + 15 = 54x - 21

    ⇒ 12x = 36

    ⇒ x = 3

    Passing marks = 42x + 15 = 42 × 3 + 15 = 126 + 15 = 141
