Question

    A shopkeeper offered two back-to-back discounts of x% and

    sold an article for Rs. 1800. The marked price was Rs. 3200. What was the percentage of each discount?
    A 10% Correct Answer Incorrect Answer
    B 18% Correct Answer Incorrect Answer
    C 20% Correct Answer Incorrect Answer
    D 25% Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    ATQ,

    3200 × (100 – x)% × (100 – x)% = 1800

    0.32 × (100 – x)² = 1800

    (100 – x)² = 5625

    100 – x = 75

    x = 25

    So, the value of ‘x’ is 25%
