    A Rs.2850 Correct Answer Incorrect Answer
    B Rs.2800 Correct Answer Incorrect Answer
    C Rs.2700 Correct Answer Incorrect Answer
    D Rs.2650 Correct Answer Incorrect Answer

    Solution

    Let the weight of stone is 10Kg. So when it breaks, the weight of parts will be 1Kg, 3Kg & 6Kg. Now it is given that Price of stone is directly proportional to square of its weight. Original price was Rs.5000 & Let new price after break be x. Price/(Weight) 2 = constant ; So 5000/(10) 2 = x /(1 2 +3 2 +6 2 ) 5000/100 = x/46 x = Rs.2300; So the loss will be = 5000 – 2300 = Rs.2700
