A fan is listed at Rs. 1500 and a discount of 20% is offered on the list price. What additional discount must be offered to the customer now to bring the net price to Rs. 1104 ?

Answer: Option A

Listed price of fan = Rs. 1500
After discount listed price
$$\begin{array}{rl}& \text{ = 80}\%\text{ of 1500}\\ & \text{ = }\frac{80}{100}\times \text{1500 }\\ & \text{ = Rs}\text{. 1200}\end{array}$$
Net price of fan = Rs. 1104
Differece = 1200 - 1104 = Rs. 96
Additional discount
$$\begin{array}{rl}& \text{ = }\frac{96}{1200}\times 100\\ & =8\%\end{array}$$
