1st article sells at 15% profit, CP : SP = 20 : 23,
the 2nd article sells at 15% loss, CP : SP = 20 : 17
Now, the selling price of two articles is the same, we make SP equal in both the ratios we get,
CP | SP | |
1st article × 17 | 340 | 391 |
2nd article × 23 | 460 | 391 |
Total | 800 | 782 |
So, 391 unit → 4000,
Then, total loss (800 - 782) = 18 unit → 4000/391 × 18 = Rs.184
