Understanding Discount Calculation in Business

Understanding how to calculate selling prices and original prices is crucial for any entrepreneur or business owner. This article will explain the process of calculating a selling price after a discount and finding the original price before a discount is applied. These calculations are fundamental for accurate pricing and financial management.

Calculating the Selling Price after Discount

Often, businesses offer discounts to attract customers. The process to find the selling price after a discount involves a simple formula:

Selling Price Marked Price - Discount

Let's consider a practical example: A shopkeeper offers a 10% discount on his articles, and the marked price of an article is Rs. 450. To find the selling price, follow these steps:

Calculate the discount amount:

Discount Marked Price × (Discount Rate / 100)

Substitute the values:

Discount 450 × (10 / 100) 450 × 0.10 45

Subtract the discount from the marked price to get the selling price:

[ Selling Price 450 - 45 405 ]

Therefore, the selling price of the article is Rs. 405.

Calculating the Original Price from the Final Price

In scenarios where the final price after discount is known, finding the original price is equally important. Here’s a method to find the original price:

Use the formula:

[ Original Price Final Price × 100 / (100 - Discount Rate) ]

Example: If the final price after a 10% discount is Rs. 450, calculate the original price:

[ Original Price 450 × 100 / 90 500 ]

The original price is Rs. 500.

Generalizing the Calculation

There are several ways to calculate the original price. Here are a couple of methods for reference:

Using a simple equation:

Let the list price be X. After a 10% discount, the price becomes 90% of X. Hence the equation:

0.9X 450

Solving for X:

[ X 450 / 0.9 500 ]

An alternative approach using cross-multiplication:

Let the original price be p. The marked price is 100p, and the final price after a 10% discount is 90% of 100p. Therefore, the equation is:

90p 450

Solving for p:

[ p 500 ]

Calculator Recommendation for Students

For students, having a reliable calculator can be a valuable tool. I recommend the TI-30 calculator as it helps in solving problems without the need for internet searches, thus fostering genuine learning. Accurate pricing calculations are crucial, and using a calculator ensures precision and efficiency.

Conclusion

Mastering the calculation of discounts, marked prices, and original prices is essential for effective business operations. Understanding these calculations not only helps in setting the right prices but also in financial management. Employing these methods ensures that businesses can make informed decisions and maintain financial health.
