-
-
12 1 % loss 2
-
12 1 % profit 2 -
11 1 % loss 9 -
11 1 % profit 2

Correct Option: C
Let the CP of each article be $ 1
∴ CP of 9 articles = $ 9
∴ SP of 9 articles = $ 8
∴ Loss = 9 - 8 = $ 1
| ∴ Loss % = | × 100 | 9 |
| Loss % = | = 11 | % | 9 | 9 |
Second method to solve this question :
Here, p = 8, q = 9
| Loss % = |  | q - p |  | × 100 | |
| q |
| Loss % = | | 9 - 8 | | × 100 | |
| 9 |
| Loss % = | = 11 | % | 9 | 9 |
