If the selling price of 4 articles is equal to the cost price of 5 articles, the profit per cent is
-
- 20%
-
22 1 % 2 - 25%
- 30%
Correct Option: C
If the CP of each article be $ 1 then
CP of 4 articles = $ 4
SP of 4 articles = $ 5
Profit = SP of 4 articles - CP of 4 articles = 5 - 4 = $ 1
| ∴ Profit percent = | × 100 % | CP of 4 articles |
| Profit percent = | × 100 = 25% | 4 |
Second method to solve this question :
Here, p = 5, q = 4
| Profit % = |  | p - q |  | × 100 | |
| q |
| Profit % = | | 5 - 4 | | × 100 | |
| 4 |
| Profit % = | = 25% | 4 |
