    B 750 Correct Answer Incorrect Answer
    C 525 Correct Answer Incorrect Answer
    D 450 Correct Answer Incorrect Answer

    Solution

    ATQ,

    Simple interest = Principal × Rate × Time ÷ 100

    Interest = 9,250 × 8 × 3 ÷ 100 = Rs. 2,220

    2k = 9,250 + 2,220

    2k = 11,470

    k = 5,735

    Product = 5 × 7 × 3 × 5 = 525
