A store sold 3 items with selling prices in the ratio 4:5:6. The profit/loss percentages are 25% profit, 15% loss, and 20% profit respectively. What is the approximate overall profit or loss percentage?
- 6.5% profit
- 8.52% loss
- 10% profit
- 10% loss
Correct answer: 6.5% profit
Solution
Let the selling prices be 4x, 5x, and 6x. Then the corresponding cost prices are \(4x/1.25=3.2x\), \(5x/0.85\approx5.882x\), and \(6x/1.2=5x\). Total SP = 15x and total CP \(\approx 14.082x\), so profit \(\approx 0.918x\), giving profit percentage \(\approx 0.918/14.082\times100 \approx 6.5\%\).
