| Option | 30% | incorrect |
| Solution | Let the selling price is 100 Profit = 20% on S.P. Now, profit = 20 So, C.P = 100- 20 = 80 Solution 1: Apply formula: Profit % = (profit/C.P) * 100 Hence, (20/80) * 100 = 25% Solution 2: Profit = Selling Price – Cost Price = 100 – 80 = 20 Profit % = (20 /80) * 100 = 25% | |
