Understanding Profit and Loss
Profit and loss are basic concepts in business and daily life. When a product is sold at a higher price than its cost price, it results in profit. Conversely, selling below the cost price leads to a loss.
Key Terms:
- Cost Price (CP): The price at which an item is purchased
- Selling Price (SP): The price at which the item is sold
- Profit: SP − CP (when SP > CP)
- Loss: CP − SP (when CP > SP)
Important Formulas:
- Profit % = (Profit / CP) × 100
- Loss % = (Loss / CP) × 100
RD Sharma solutions provide step-by-step methods to solve such problems, making it easier for students to calculate percentages and understand real-life scenarios.
Concept of Discount
Discount is a reduction given on the marked price of an item. It is commonly used in sales and promotional offers.
Key Terms:
- Marked Price (MP): The original price labeled on an item
- Discount: Reduction in price
- Selling Price (SP): MP − Discount
Discount Formula:
- Discount % = (Discount / MP) × 100
The solutions in RD Sharma help students understand how to calculate final prices after discounts and how different percentages affect the selling price.
Value Added Tax (VAT)
VAT is a type of tax applied to goods and services. It is included in the final price paid by the consumer.
VAT Formula:
- VAT = (VAT Rate × Cost Price) / 100
- Final Price = Cost Price + VAT
RD Sharma solutions guide students in solving VAT-related problems, ensuring they understand how taxes are calculated in real-world transactions.

FAQs for RD Sharma Class 8 Maths Solutions Chapter 13 – Profit, Loss, Discount & VAT
Profit and discount are two different financial concepts used in business transactions. Profit is the gain earned when the selling price of a product exceeds its cost price, while discount is the reduction given on the marked price to attract customers. Profit depends on cost price and selling price, whereas discount is applied before the final selling price is determined. Understanding both concepts is important because they influence how businesses set prices and how customers make purchasing decisions in everyday situations.
VAT is calculated by applying a percentage rate to the cost price of a product. To find VAT, multiply the cost price by the VAT rate and divide by 100. After calculating VAT, add it to the cost price to get the final price paid by the consumer. In Class 8 maths, students learn simple VAT problems where the rate is given, and they must calculate the tax amount and total cost. Practicing these problems helps students understand how taxes are applied in real-life purchases.
