Introduction to Profit and Loss

This page introduces the terms cost-price, sale-price, overhead-expenses, profit, and loss. It explains that the shopkeeper invested cost-price and so profit is calculated as a percent of the amount invested.

Profit percent `= 100 xx` (sale price - cost price) `//` cost price.
