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?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%
