Question

Music CD originally priced at Rs 120 is on sale for 25% off. What is the S.P.? 

Sonia and Rahul have different ways of calculating the sale price for the items they bought.

As you work on the next problem, try both of these methods to see which you prefer

Answer 1

Given, price of CD = 120

Also, discount is 25% of original price.

We need to find out selling price.

⇒ Now, we know x% of n = x/100 x n

⇒25% discount on Rs.120 = 25/100 x 120

= 120/4

= Rs. 30

∴ Discount = Rs.30

⇒Now, Selling price after discount = original cost price - discount

⇒ Selling price after discount = 120-30

= Rs.90

Hence, the selling price is RS.90
