    Question

    A dishonest dealer claims to sell goods at cost price

    but uses a false weight of 900g instead of 1kg. What is his profit percentage?
    A 10% Correct Answer Incorrect Answer
    B 11.11% Correct Answer Incorrect Answer
    C 12.5% Correct Answer Incorrect Answer
    D 14.66% Correct Answer Incorrect Answer

    Solution

    Let the cost price of 1kg be 100.  The dealer sells 900g for 100, so his effective cost for 900g is 100 × 900/1000 = 90 Profit = 100 - 90 = 10 Profit percentage = 10/90 × 100 ~ 11.11%
