    A watch worth Rs. 5400 is offered for sale at Rs. 4500. What percent discount is offered during the sale?

    A)  50/3               

    B)  49/3   

    C)  25/3   

    D)         34/3   

    Correct Answer: A

    Solution :

    We have, \[\text{M}\text{.P}\text{. = Rs}\text{. 5400}\]and \[\text{S}\text{.P}\text{. = Rs}\text{. 4500}\] \[\therefore \]Discount \[\text{= M}\text{.P}\text{.-S}\text{.P}\text{.}\] \[\text{= Rs}\text{. 5400 - Rs}\text{. 4500 = Rs}\text{. 900}\] Thus. Discount \[\text{ }\!\!%\!\!\text{ =}\left( \frac{\text{Discount}}{\text{M}\text{.P}\text{.}}\text{ }\!\!\times\!\!\text{ 100} \right)\]             \[\text{=}\left( \frac{900}{5400}\times 100 \right)=\frac{50}{3}\]
