A shopkeeper bought 200 articles, each costing the same. He sold 30% of the articles at 20% profit and remaining at 10% profit. If the total profit made by him is $ 2600, find the cost price of one article.
-
- $ 200
- $ 1300
- $ 2600
- $ 100
Correct Option: D
Let C.P. of each article = $ 1
∴ Total C.P. = $ 200
| Total S.P. = | + | 100 | 100 |
Total S.P. = 72 + 154 = $ 226
Gain = Total S.P. - Total C.P. = 226 – 200 = $ 26
When gain = $ 26 , C.P. = $ 1
When gain = $ 2600, C.P. = $ 100
