    A person sells a table at a profit of 10% If he had bought the table at 5% less cost and sold for Rs. 80 more, he would have gained 20%. The cost price of the table is    

    A)                              Rs. 3200

    B)  Rs. 2500          

    C)  Rs. 2000

    D)  Rs. 2200   

    Correct Answer: C

    Solution :

    Suppose CP of table = Rs. x SP \[=\frac{x\times 110}{100}=\frac{11x}{10}\] CP at 5% less \[=\frac{x\times 95}{100}=\frac{19x}{20}\] According to the question,\[\frac{19x}{20}\times \frac{120}{100}=\frac{11x}{10}+80\] \[\Rightarrow \]   \[\frac{57x}{50}-\frac{11x}{10}=80\] \[\Rightarrow \]   \[\frac{2x}{50}=80\] \[\therefore \]      \[x=\frac{80\times 50}{2}\]= Rs. 2000
