Profit & Loss

Cost Price: The price at which a retailer buys a product.

Selling Price: The price at which a retailer sells a product.

When Selling Price $>$ Cost Price, a retailer makes a Profit.

$$Profit = Selling\;Price - Cost\;Price$$

$$\%\;Profit = \frac{Profit}{Cost\;Price} \times 100\%$$

When Selling Price $<$ Cost Price, a retailer incurs a Loss.

$$Loss = Cost\;Price - Selling\;Price$$

$$\%\;Loss = \frac{Loss}{Cost\;Price} \times 100\%$$

Marked Price: The price displayed before discount.

Discount: The amount deducted from the marked price.

Discounted Price: The selling price after discount.

$$Discount = Marked\;Price - Discounted\;Price$$

$$\%\;Discount = \frac{Discount}{Marked\;Price} \times 100\%$$
