By selling an article for Rs. 204, there is a loss of 15%, when the article is sold for Rs. 268.8, the net result is?

12% gain

Loss of 15% → SP = 85% of CP

\(\frac{85}{100}\) CP = 204                           

CP = 240                                              

now, new SP = 268.8

then,  gain = 268.8 - 240 = 28.8

gain % = \(\frac{28.8}{240}\) × 100% = 12%
