Calculating discount is an essential skill for anyone who wants to make informed purchasing decisions or manage a business effectively. In this guide, we will walk you through the process of calculating discount step by step.
Step 1: Determine the Original Price
The first step in calculating discount is to determine the original price of the item. This is usually the price marked on the product or listed in the catalog.
Step 2: Determine the Discount Percentage
Next, you need to determine the discount percentage. This is usually advertised as a percentage off the original price, such as "10% off" or "20% discount."
Step 3: Convert the Discount Percentage to a Decimal
To calculate the discount, you need to convert the discount percentage to a decimal. To do this, divide the discount percentage by 100. For example, if the discount percentage is 10%, you would divide 10 by 100 to get 0.1.
Step 4: Calculate the Discount Amount
Now that you have the original price and the discount decimal, you can calculate the discount amount. To do this, multiply the original price by the discount decimal. For example, if the original price is rs100 and the discount decimal is 0.1, you would multiply rs100 by 0.1 to get rs10.
Step 5: Calculate the Discounted Price
Finally, you can calculate the discounted price by subtracting the discount amount from the original price. For example, if the original price is rs100 and the discount amount is rs 10, you would subtract rs 10 from 100 to get a discounted price of rs 90.
Formula for Calculating Discount
The formula for calculating discount is:
Discount = Original Price x Discount Percentage
Discounted Price = Original Price - Discount
Example
Suppose you want to buy a shirt that is originally priced at rs 50. The store is offering a 15% discount on all shirts. To calculate the discount, you would:
1. Determine the original price: rs 50
2. Determine the discount percentage: 15%
3. Convert the discount percentage to a decimal: 15 ÷ 100 = 0.15
4. Calculate the discount amount: rs 50 x 0.15 = rs7.50
5. Calculate the discounted price: rs 50 - rs 7.50 = rs 42.50
Therefore, the discounted price of the shirt would be rs 42.50.
