A wholesaler sells 20 pens at the marked price (printed on the article) of 16 pens to a retailer. The retailer in turn sells them at the marked price . Determine the gain or loss per cent to the retailer.
-
- 25% loss
- 25% profit
- 20% loss
- 20% profit
Correct Option: B
Let the marked price of 1 pen = $ 100
∴ MP of 20 pens = 20 × 100 = $ 2000
MP of 16 pens = 16 × 100 = $ 1600
CP of 20 pens for retailer = $ 1600
SP of 20 pens for retailer = $ 2000
∴ Profit = 2000 - 1600 = $ 400
| Profit% = | × 100 | CP of 20 pens for retailer |
| Profit% = | × 100 = 25% | 1600 |
