Important Topics for RD Sharma Class 8 Maths Solutions Chapter 13: Profit Loss Discount And Value Added Tax

Profit and loss

  • It is a financial statement that comprises the revenue, cost, and expenses incurred by a company during a period of time, usually a fiscal year.

Selling price and cost price

  • The price at which a product or service is sold to the buyer by the seller is called the selling price. The selling price is calculated by adding the cost price and profit margin set by the seller.
  • The cost price, on the other hand, is the cost that is involved in the production of an item or to provide a service to the buyer. The formula of cost price is selling price x 100 / 100 – percentage loss. 

Discounts and Percentage

  • A discount is a reduction given on the market price of an article. A discount can be calculated by subtracting the market price by sale price. So, discount price =  market price – sale price.
  • For example, if an item marked as 840 is sold for 714. What will be the discount and discount%? 

We know that the discount will be 840-714 = 129. Now, the percentage will be calculated by dividing the discount from the marked price and then multiplying it by 100 i.e 126/840 x 100 = 15%.


  • Profit refers to financial gain. Especially, profit is the difference between the amount spent and the amount earned in buying, producing something or operating. 
  • For example, if Sheela sells a lucky dip at Rs.10. She spends Rs.5 to purchase it, and Rs. 3 to wrap it with paper. She spends a total of Rs.8 and sells at Rs.10. This gives her a profit of Rs.2. 

To find the profit percentage, you need to divide profit with the total expenditure done, i.e, Profit (Rs.2) / Expenditure (Rs.8) x 100% = 25% only. 

Compound interest

  • Compound interest is an interest that includes all of the accumulated previous year interests on a loan. 
  • It is calculated by initial principal x ( 1 + annual interest rate raised to the number of compound periods -1)

Sales Tax/Value-Added Tax/Goods and Service tax

  • Sales tax is the tax that is added by the government on the purchase of a particular item. This tax is then collected by the shopkeeper from the customer and they give it to the government.
  • For example, these types of questions can be asked in such a way that if a roller skate at a shop is the cost at the rate of Rs 450 and the tax charged is 5% then what will be the total bill of roller skates?

Now, if the tax is charged on Rs 100 is Rs 5, then on Rs 450 taxes charged will be 5/100 x 450 = 22.50. So your bill will be the cost of the item + sales tax i.e 450 + 22.50 = 472.50.
