    Question

    The cost of 5 guns is equal to the cost of 12 magazines.

    If a seller marks the price of each gun 50% higher than its cost price and gives away one magazine for free with each gun, what will be the profit the seller makes on each sale?
    A 5.88% Correct Answer Incorrect Answer
    B 12.5% Correct Answer Incorrect Answer
    C 7.14% Correct Answer Incorrect Answer
    D 8.83% Correct Answer Incorrect Answer

    Solution

    Let the cost price of 5 guns be Rs. '60x' So, cost price of each gun = 60x ÷ 5 = Rs. '12x' And cost price of each magazine = 60x ÷ 12 = '5x' So, marked price of each gun = 12x X 1.5 = Rs. '18x' So, profit earned on selling each gun = 18x - 12x - 5x = Rs. 'x' So, required percentage = {x/(12x + 5x)} X 100 ~ 5.88%
