    and sold it after two successive discounts of d% and 37.5% and incurred a loss of 30%. Find the value of ‘d’
    A 10 Correct Answer Incorrect Answer
    B 15 Correct Answer Incorrect Answer
    C 25 Correct Answer Incorrect Answer
    D 20 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Let cost price of the article be Rs. 100x Marked price of the article = 1.40 × 100x = Rs. 140x Selling price of the article = 0.70 × 100x = Rs. 70x Overall discount = [(140x – 70x)/140x] × 100 = 50% So, 37.5 + d – {(37.5 × d)/100} = 50 => 0.625d = 12.5 => d = 12.5/0.625 => d = 20
