A merchant marks his wares 40% more than the real price and allows 20% discount. His profit is
20%
18%
16%
12%
None of these
Let the cost price be 100. Marked price = 140. Discount = 20% of 140 = 28. Selling price = 140 - 28 = 112. Profit = 112 - 100 = 12%.
Let the real price or cost price be Rs 100. The merchant marks the ware 40% higher, making the marked price Rs 140. He then allows a 20% discount on this marked price, calculating the selling price as 140 - (140 * 0.20) = Rs 112. The profit percentage is found using the formula ((Selling Price - Cost Price) / Cost Price) * 100, resulting in ((112 - 100) / 100) * 100 = 12%.
