How to find Profit or loss using Python when CP of N items is equal to SP of M

Vikram Chiluka
Updated on 24-Jan-2023 19:13:18
In this article, we will learn a python program to find the profit or loss when the cost price CP of N items is equal to the selling price SP of M items. Assume we have taken N, and M values which represent the cost price of N items are equal to the selling price of M items. We will now calculate the profit or loss percentage. Formula profit/loss = ( (Cost Price) - (Selling Price) ) / (Selling Price) * 100 What is the Selling Price(SP)? The price a consumer pays to purchase a product or a commodity ... Read More
