    C) Rs. 750             

    D) Rs. 817.50

    Correct Answer: C

    Solution :

    Let the marked price of the watch=Rs. x Then             \[\frac{x\times (100-5)}{100}-\frac{x\times (100-7)}{100}=15\]                                                 \[\frac{95x}{100}-\frac{93x}{100}=15\]  \[2x=1500\] \[x=Rs.\,\,750\]
