    A man sells an article at 10% loss. If he had sold it at Rs. 10 more, he would have gained 10%. The cost price of the article is

    A)  Rs. 50 

    B)  Rs. 55

    C)  Rs. 100            

    D)  Rs. 110

    Correct Answer: A

    Solution :

    Let the CP be Rs. x. First selling price             \[=90%\,\,\text{of}\,\,x\,\,\text{=}\,\,\text{Rs}\text{.}\frac{9x}{10}\] Second selling price \[\text{=}\,\,\text{Rs}\text{.}\left( \frac{9x}{10}+10 \right)\] \[\therefore \] \[\text{110 }\!\!%\!\!\text{ }\,\,\text{of}\,\,x\,\,\text{=}\,\,\text{Rs}\text{.}\left( \frac{9x}{10}+10 \right)\] \[\Rightarrow \]   \[\frac{11x}{10}=\frac{9x}{10}+10\] \[\Rightarrow \]   \[\frac{2x}{10}=10\] \[\Rightarrow \]   \[x=\frac{10\times 10}{2}=50\]
