Introduction

In the world of business, profit is the ultimate goal for any shopkeeper. The profit is calculated by subtracting the cost price from the selling price. However, the question arises when the shopkeeper sells an article at a price that is $25\%$ above the cost. In this article, we will explore the concept of profit percent and how to calculate it when the selling price is higher than the cost price.

Understanding the Cost Price and Selling Price

The cost price of an article is the price at which the shopkeeper purchases the article from the supplier. On the other hand, the selling price is the price at which the shopkeeper sells the article to the customer. When the shopkeeper sells an article at a price that is $25\%$ above the cost, it means that the selling price is $125\%$ of the cost price.

Example

Cost Price and Selling Price

Let's consider an example to understand the concept better. Suppose the cost price of an article is $100. If the shopkeeper sells the article at a price that is $25\%$ above the cost, the selling price will be $125\%$ of $100, which is $125.

Cost Price	Selling Price
$100	$125

Calculating the Profit Percent

The profit percent is calculated by finding the difference between the selling price and the cost price, and then dividing it by the cost price. In this case, the profit percent can be calculated as follows:

Profit Percent = ((Selling Price - Cost Price) / Cost Price) × 100

Example

Calculating the Profit Percent

Using the example above, we can calculate the profit percent as follows:

Profit Percent = ((125 - 100) / 100) × 100 = (25 / 100) × 100 = 25%

Conclusion

In conclusion, when the shopkeeper sells an article at a price that is $25\%$ above the cost, the profit percent can be calculated by finding the difference between the selling price and the cost price, and then dividing it by the cost price. In this case, the profit percent is $25\%$ . This concept is essential for shopkeepers to understand, as it helps them to determine the profit margin and make informed decisions about pricing and inventory management.

Formula for Profit Percent

The formula for profit percent is:

Profit Percent = ((Selling Price - Cost Price) / Cost Price) × 100
