    A) Rs. 650

    B) Rs. 800

    C) Rs. 700

    D) Rs. 850

    Correct Answer: B

    Solution :

    [b] CP = Rs. 600, Profit = 20%, Discount = 10% Let, Marked Price = Rs. x \[\therefore \]      \[SP=x-\frac{x\times 10}{100}=\frac{90x}{100}=\text{Rs}\text{.}\,\,\frac{9x}{10}\] Now,     \[CP=CP\frac{(100+\text{profit}%)}{100}\] \[\Rightarrow \]   \[\frac{9x}{10}=600\times \frac{(100+20)}{100}\] \[\Rightarrow \]   \[\frac{9x}{10}=6\times 120\]\[\Rightarrow \]\[x=\frac{6\times 120\times 10}{9}\] \[\Rightarrow \]   \[x=\text{Rs}.\,800\]
