Question

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

Answer 1

Marked price of a watch = Rs. 5400
Selling price = Rs. 4500
Discount = Marked price - Selling price = Rs 5400 - Rs. 4500 = Rs. 900
$\therefore \text{Discount}\%=\frac{\text{Discount}}{\text{Marked~price}}\times 100$
=$\frac{900}{5400}\times 100$
=$\frac{900}{54}=\frac{450}{27}=\frac{150}{9}=\frac{50}{3}\%$
