    C Rs.2250 Correct Answer Incorrect Answer
    D Rs.2356 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Let the weight of stone is 10Kg. So when it breaks, the weight of parts will be 2Kg, 3Kg & 5Kg. Now it is given that Price of stone is directly proportional to square of its weight. Original price was Rs.3800 & Let new price after break be x. Price/(Weight) 2 = constant ; So 3800/(10) 2 = x /(2 2 +3 2 +5 2 ) 3800/100 = x/38 x = Rs.1444; So the loss will be = 3800 – 1444 = Rs.2356
