If the cost price of 25 pens is equal to the selling price of 20 pens, then the profit per cent is
-
- 20%
- 25%
- 15%
- 5%
Correct Option: B
Let the C.P. of each pen be Re. 1.
∴ C.P. of 20 pens = Rs. 20
∴ S.P. of 20 pens = Rs. 25
Profit = S.P. of 20 pens - C.P. of 20 pens = 25 - 20 = Rs. 5
| ∴ Profit percent = | × 100 | C.P. of 20 pens |
| Profit percent = | = 25% | 20 |
