    Question

    A seller makes a profit of 20% by selling 45 kg of pure

    sugar. Later, he mixes some impurities into the sugar and sells the entire mixture at the original cost price of pure sugar. How much impurity (in kg) did he mix into the sugar?
    A 7.5 kg Correct Answer Incorrect Answer
    B 14.5 kg Correct Answer Incorrect Answer
    C 6.6 kg Correct Answer Incorrect Answer
    D 10.5 kg Correct Answer Incorrect Answer
    E 18.4 kg Correct Answer Incorrect Answer

    Solution

    Let cost price of 1 kg of sugar = ₹100
    Selling price of 45 kg of sugar = ₹4500
    Cost price of 45 kg of sugar = ₹4500 *(100/120) = ₹3750
    Total weight of sugar = 3750/100 = 37.5 kg
    Hence, the weight of impurities in 45 kg of sugar = 45 - 37.5 = 7.5 kg
