Answer:
Discount % = (Discount/List Price) × 100
Step-by-step explanation:
To calculate the discount, you must have the list price (marked price) and the selling price of the product you are buying.
Example: If the list price of a book is $50, and $10 discount is offered on the book, then the discount percentage is calculated as follows.
Discount % = (Discount/List Price) × 100
List price = $50; discount = $10
Discount (%) = (10/50) × 100
= 100/5
= 20%
