Question

A fan is listed at Rs. 150 with a discount of 20% . What additional discount must be offered to the customer to bring the net price to Rs. 108 ?

A) 11 1/9% B) 15% C) 8% D) None of these

Answer 1

Answer:

An additional discount is 10%

Step-by-step explanation:

Cost price of fan= rs.150

Discount % = 20%

Cost after discount =150-20\% \times 150 = 150- 0.2(150)=120

let the another discount % be x%

So, Cost after another discount =120-x\%(120)=120-\frac{120x}{100}

We are given that the net price rs 108

So, 120-\frac{120}{100}x=108\\12=\frac{120}{100}x\\\frac{1200}{120}=x\\10=x

Hence An additional discount is 10%
