1. Cost Price
Cost price is the total amount of money that it costs a manufacturer to
produce a given product or provide a given service.
The selling price of a product or service is the seller’s final price, i.e.,
how much the customer pays for something. The exchange can be for
a product or service in a certain quantity, weight, or measure.
Selling Price

2. Profit
a financial gain, especially the difference between the amount earned and the
amount spent in buying, operating, or producing something
i.e. If selling price is more than cost price then we get PROFIT
Profit= Selling Price-Cost Price

3. Loss
If selling price is less than the cost price then we get LOSS
Loss= Cost Price-Selling Price

4. Example
If selling price of one notebook is Rs. 100 and the cost price is Rs. 80. What is
the Profit and Loss
Selling Price=Rs.100 & Cost Price=Rs.80
Selling Price is more than Cost Price
Therefore Profit=Rs.100-Rs.80=20 Rs.

5. Example
If selling price of one book is Rs. 80 and the cost price is Rs. 90. What is the
Profit and Loss
Selling Price=Rs.80 & Cost Price=Rs.90
Selling Price is less than Cost Price
Therefore Loss=Rs.90-Rs.80=10 Rs.
