Question

    The price of sugar is increased by 15%. If the

    expenditure is not allowed to increase, the ratio between the reduction in consumption and the original consumption is:
    A 3:23 Correct Answer Incorrect Answer
    B 1:11 Correct Answer Incorrect Answer
    C 4:15 Correct Answer Incorrect Answer
    D 2:21 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Let the price of sugar was Rs. x per kg. After increase in price, new price per kg = x + (x × 15/100) = 23x/20 For Rs. 23x/20 we get 1 kg of sugar. For Re. 1 we get 20/23x kg of sugar. For Rs. x we get 20/23 kg of sugar. Decrease in consumption of sugar = 1 – 20/23 = 3/23 Required ratio = 3/23 : 1 = 3:23
