What is a Discount Ratio?

A Discount Ratio is a percentage that represents the amount of discount given on the original price of an item. It is calculated by dividing the total discount by the original price and then multiplying by 100 to get a percentage.

Why is calculating the Discount Ratio useful?

Calculating the Discount Ratio is useful for both consumers and retailers to understand the exact percentage of the discount being offered. This helps in comparing discounts across different products or services and making more informed purchasing decisions.

Can the Discount Ratio be more than 100%?

No, the Discount Ratio cannot be more than 100%. A Discount Ratio of 100% would mean the item is being offered for free, and anything above 100% would imply the seller is paying the buyer to take the item, which is not a typical scenario in commerce.

How does a Double Discount affect the Discount Ratio?

A Double Discount involves applying two successive discounts to an original price. This affects the Discount Ratio by making it larger than if only a single discount were applied. However, the calculation must account for the compounded effect of the two discounts, not just summing the percentages.
