    A 1,650 Correct Answer Incorrect Answer
    B 1,050 Correct Answer Incorrect Answer
    C 1,500 Correct Answer Incorrect Answer
    D 1,320 Correct Answer Incorrect Answer

    Solution

    Let the marked price be ₹x. Selling price with 65% discount = x × 0.35
    Selling price with successive 30% and 40% discounts = x × 0.70 × 0.60 = x × 0.42 Difference = x × 0.42 − x × 0.35 = 105
    x(0.42 − 0.35) = 105
    x × 0.07 = 105
    x = 105 / 0.07 = ₹1500
