    A 152 Correct Answer Incorrect Answer
    B 135 Correct Answer Incorrect Answer
    C 162 Correct Answer Incorrect Answer
    D 148 Correct Answer Incorrect Answer

    Solution

    ATQ,

    Let the total marks be 100x

    Neha’s marks = 0.46 × 100x = 46x

    Passing marks = 46x + 10

    Kunal’s marks = 0.52 × 100x = 52x

    Passing marks = 52x - 8

    So, 46x + 10 = 52x - 8

    ⇒ 6x = 18

    ⇒ x = 3

    Passing marks = 46x + 10 = 46 × 3 + 10 = 138 + 10 = 148
