    A trades man sold an article at a loss of 20%. If the selling price had been increased by Rs. 100, there would have been a gain of 5%. The cost of the price of the article was

    A)  Rs. 200            

    B)  Rs. 25

    C)  Rs. 400

    D)  Rs. 250

    Correct Answer: C

    Solution :

    Let the cost price of an article = Rs. x \[\therefore \] SP of the article \[=Rs.\frac{80}{100x}=Rs.\frac{4x}{5}\] New SP of the article \[=Rs.\frac{4x}{5}+100\] \[\therefore \]      \[\frac{4x}{5}+100=\frac{105x}{100}\] \[\Rightarrow \]   \[\frac{4x}{5}+100=\frac{21x}{20}\] \[\Rightarrow \]   \[\left( \frac{21-16}{20} \right)x=100\] \[\Rightarrow \]   \[x=\frac{100\times 20}{5}=400\]
