Ravi bought certain apples in wholesale. He then marked up the price of the apples by 50 percent more. He sold one third of the apples but then he was not getting any buyers. So he started offering a discount of 10 % on the marked price. After selling half of the remaining apples, he was again not getting any buyers. Hence, he sold the remaining apples at a discount of 20 % on the marked price. What is his overall profit percentage in this transaction?

Let cost price of each apple be 100. Marked price = 150. First batch (1/3 sold): sells at 150, revenue = 50 × 150 = 7500. Remaining apples = 100. Second batch (half of remaining = 50): sold at 10% discount, price = 135, revenue = 50 × 135 = 6750. Final batch (50 apples): sold at 20% discount, price = 120, revenue = 50 × 120 = 6000. Total revenue = 7500+6750+6000 = 20250. Total cost = 100 × 100 = 10000. Profit = 20250-10000 = 10250. Profit % = (10250/10000) × 100 = 102.5%, so overall is 35% profit.
