| A tradesman prices his goods so as to gain 5%. A fall of 10% in the wholesale price occurs and he alters his selling price so as to gain 10% under the new conditions. A customer now purchases an article at Rs. 12 less than before. The former price of the article was |
A) 200
B) 125
C) 190
D) 188
Correct Answer: A
Solution :
| Let original \[CP=100x\] |
| Original \[SP=105x\] |
| Present \[CP=90x\] |
| Present\[SP=\frac{11}{10}\times CP=\frac{11}{10}\times 90x=99x\] |
| Difference between\[SP=105x-99x=99x\] |
| But \[6x=12\]\[\Rightarrow \]\[x=2\] |
| \[\therefore \]Original \[CP=100\times 2=200\] |
