    Question

    A trader cheats by using a weighing scale that shows 1

    kg while actually giving only 900 grams. He also marks up the goods by 25% and then gives a 10% discount. What is his profit percentage?
    A 10% Correct Answer Incorrect Answer
    B 25% Correct Answer Incorrect Answer
    C 34% Correct Answer Incorrect Answer
    D 28% Correct Answer Incorrect Answer

    Solution

    ATQ,

    Let the quantity of goods sold = 1000 grams

    Let the price of goods be Rs. x per gram

    Marked price = 1000x × 1.25 = Rs. 1250x

    Selling price = 1250x × 0.9 = Rs. 1125x

    Cost price = 900x
