Profit and Loss in Mathematics

Profit and Loss in Mathematics

• Profit is the financial gain from a transaction. It's calculated as the selling price minus the cost price.
• Loss is the financial loss from a transaction. It's calculated as the cost price minus the selling price.
• Profit percentage expresses profit as a percentage of the cost price. Formula = (Profit / Cost Price) * 100
• Loss percentage expresses loss as a percentage of the cost price. Formula = (Loss / Cost Price) * 100

Calculating Profit and Loss

• To calculate profit or loss, first identify the cost price (CP) and the selling price (SP).
• If SP > CP, there is a profit.
• If SP < CP, there is a loss.
• The profit or loss amount is the difference between the selling price and cost price.
• Profit = SP - CP
• Loss = CP - SP

Profit and Loss Percentage

• Profit percentage = ((SP - CP) / CP) * 100
• Loss percentage = ((CP - SP) / CP) * 100
• These percentages show the profitability or loss rate relative to the initial investment.

Example Scenarios

• Scenario 1: A shopkeeper buys an item for 10andsellsitfor10 and sells it for 10andsellsitfor15. Profit is $5. Profit percentage = (5/10) * 100% = 50%
• Scenario 2: A farmer buys a cow for 500andsellsitfor500 and sells it for 500andsellsitfor400. Loss is $100. Loss percentage = (100/500) * 100% = 20%

Multiple Transactions

• In cases with multiple transactions, calculate the profit or loss for each transaction individually then combine them if necessary.
• This could be on items bought and sold, investments made or costs incurred.

Mark Up and Mark Down

• Markup is the difference between the selling price and the cost price, expressed as a percentage of the cost price.
• Markdown is a reduction in the price of goods or services.
• Markup percentage = (Selling Price - Cost Price) / Cost Price x 100
• Markdown percentage = (Discount Amount) / Original Price x 100

Discount Calculation

• Discount is a reduction in the price of a product or service.
• Discount amount is calculated as a percentage of the original price.
• Discounted price = Original Price - Discount amount
• Example: An item with an original price of 100anda10100 and a 10% discount has a discount amount of 10% x 100anda10100 = 10.Thediscountedpriceis10. The discounted price is 10.Thediscountedpriceis100 - 10=10 = 10=90
