    A man purchased a watch for Rs.  400 and sold it at a gain of 20% of the selling price. The selling price of the watch is

    A) Rs. 300

    B)  Rs. 320

    C)  Rs. 440

    D)  Rs. 500

    Correct Answer: D

    Solution :

    Let selling price = Rs. x Then, \[400+20%\] of \[x=x\]\[\Rightarrow \]\[400+\frac{x}{5}=x\] \[\Rightarrow \]   \[\frac{4x}{5}=400\]\[\Rightarrow \]\[x=\frac{400\times 5}{4}\] \[\Rightarrow \]   \[x\]Rs. 500 \[\therefore \] Selling price = Rs. 500
