A discount is an amount deducted from the actual price of an article. If you receive a discount, you pay less than the advertised selling price of the article.

Example

A man receives 10% discount for cash payment when buying a suit for him and pays 63,450 FRS. What discount does he receive?.

Solution

The original price of the suit is 100% of the price

The ratio of discount to the original price= 10: 100

The man pays 90% of the original price

The ratio of the discount to the cash price is 10:90

 .: the discount is 10/90 of the cash price

= 1090×63,450FRS

= 7,050 FRS
