    Question

    A dairy owner buys 20 liters of milk at Rs. 50 per liter.

    While selling, he uses a faulty measure that shows 1020 milliliters instead of 1000 milliliters but claims to sell it at a profit of 10%. Find the total profit earned by him from selling the milk bought by him.
    A Rs.212 Correct Answer Incorrect Answer
    B Rs.122 Correct Answer Incorrect Answer
    C Rs.187 Correct Answer Incorrect Answer
    D Rs.185 Correct Answer Incorrect Answer

    Solution

    ATQ,

    Cost price of 20 liters of milk = 50×20 = Rs.1000

    Quantity of milk sold = 1.02×20 = 20.4 liters

    Selling price of 20 liters of milk sold = (1.10×50)×20.4 = Rs.1122

    Required profit = 1122−1000 = Rs.122
