    A Rs.550 Correct Answer Incorrect Answer
    B Rs.700 Correct Answer Incorrect Answer
    C Rs.900 Correct Answer Incorrect Answer
    D Rs.200 Correct Answer Incorrect Answer

    Solution

    ATQ,

    Let the new price of the product be Rs. '100x'

    So, old price of the product = 100x × 0.6 = Rs. '60x'

    So, 100x - 60x = 600

    So, 40x = 600

    So, x = 15

    So, old price of the product = 15 × 60 = Rs. 900
