Question
D-Mart sold two toys - one at 10% loss and another at
20% profit. What is the percent profit or loss if the cost prices of the toys are in the ratio 3:2?Solution
Let the cost prices of the toys be ₹300 and ₹200 respectively. Selling price of the first toy = 300 * 0.9 = ₹270 Selling price of the second toy = 200 * 1.2 = ₹240 Total cost price of both the toys = 300 + 200 = ₹500 Total selling price of both the toys = 270 + 240 = ₹510 ∴ Total profit = ₹10 ∴ Profit% = 10/500 * 100 = 2%
