What is Meant by Discount?

In mathematics, the discount is a type of reduction in the cost price of a product. Generally, the discount refers to the condition where the selling price of the product is less than the cost price of the product. The discount can be calculated by taking the difference between the cost price and the selling price. Thus, the formula to determine the discount is given as:

Discount = Cost price – Selling Price

For example, the actual cost of the pen is Rs. 70, but the shopkeeper has sold the pen for Rs. 50, thus the discount can be calculated by

Discount = Actual cost of the pen(cost price) – Sold price (selling price)

Discount = 70 – 50

Hence, the shopkeeper has sold the pen with a discount of Rs.20.
