    By selling a table for Rs 330, a trader gains 10%. Find the cost price of the table.

    A)  300               

    B)         363                 

    C)         297               

    D)         270

    Correct Answer: A

    Solution :

    S.P. = Rs 330, Gain = 10% \[\therefore \]     C.P. \[=\left( \frac{100}{100+Gain%} \right)\times S.P.\] \[=Rs\,\frac{100}{100+10}\times 330\] \[=\frac{100}{110}\times 330=Rs.300.\]
