A) 12% gain
B) 12% loss
C) 10% loss
D) 15% gain
Correct Answer: A
Solution :
| Here, SP = Rs. 102 |
| Loss per cent =15% |
| CP of article \[=\frac{\text{100}\times \text{SP}}{\text{100}-\text{Loss}\,\,\text{per}\,\,\text{cent}}\] |
| \[=\frac{100\times 102}{100-15}=\frac{10200}{85}=\text{Rs}\text{.}\,\,\text{120}\] |
| Now, the article is sold for Rs. 134.40 |
| Here, \[\text{SP}>\text{CP}\] |
| \[\therefore \]Profit percent \[=\frac{\text{SP}-\text{CP}}{\text{CP}}\times 100\] |
| \[=\frac{134.40-120}{120}\times 100\] |
| \[=\frac{14.40\times 100}{120}=\frac{1440}{120}=12\]% |
