A person bought some articles at the rate of 5 per rupee and the same number at the rate of 4 per rupee. He mixed both the types and sold at the rate of 9 for 2 rupees. In this business he suffered a loss of $ 3. The total number of articles bought by him was
-
- 1090
- 1080
- 540
- 545
Correct Option: B
Let the person buy 10 articles.
| Total CP = $ |  | 1 + | 5 |  | ||
| 4 |
| Total CP = $ | 4 |
| SP of 10 articles = $ | × 10 = $ | 9 | 9 |
Now, if loss is $ (1 / 36), number of articles = 10
∴ If loss is 3, number of articles = 36 × 10 × 3 = 1080
