The ratio of cost price and selling price is 5 : 4, the loss percent is :
-
- 20%
- 25%
- 40%
- 50%
Correct Option: A
Here , cost price : selling price = 5 : 4
According to the question
| = | Selling price | 4 |
| ∴ Selling price = | × Cost price | 5 |
Loss = Cost price – Selling price
| Loss = Cost price – | Cost price | 5 |
| Loss = | Cost price | 5 |
| ∴ Loss % = | = | = 20% | cost price | 5 |
Second method to solve this question :
$ 1 is loss on $ 5.
| ∴ loss % = | × 100 = 20% | 5 |
We can find required answer with the help of given formula :
Here, C.P. = 5k, S.P. = 4k
| loss % = | × 100 | C.P. |
| loss % = | × 100 = 20% | 5k |
