    B Rs 5400 Correct Answer Incorrect Answer
    C Rs 5600 Correct Answer Incorrect Answer
    D Rs 5800 Correct Answer Incorrect Answer

    Solution

    Let the sum invested at compound interest be Rs. x
    According to the question,
    x(1 + 5/100) 2 = 4410.25
    or, x = 4410.25/1.1025 = Rs. 4000
    Required amount received = {(4000 × 15 × 3)/100} + 4000 = Rs. 5800
