Profit, Loss & Discount — solved examples for Class 7 ICSE

Example 1easy

Which of the following statements correctly defines 'Profit' in commercial transactions?
  1. A)Profit is the amount saved when buying an item.
  2. B)Profit is calculated when the Cost Price (CP) is greater than the Selling Price (SP).
  3. C)Profit is the extra amount gained when the Selling Price (SP) is greater than the Cost Price (CP).
  4. D)Profit is the percentage reduction on the Marked Price (MP).

Step-by-step solution

  1. Cost Price (CP) is the price at which an item is bought.
  2. Selling Price (SP) is the price at which an item is sold.
  3. Profit occurs when SP > CP, and it is calculated as Profit = SP - CP.

Answer: Profit is the extra amount gained when the Selling Price (SP) is greater than the Cost Price (CP).

Example 2medium

A shopkeeper bought a set of books for ₹1200 and sold them for ₹1380. What was the profit or loss amount made by the shopkeeper?
  1. A)Loss of ₹180
  2. B)Profit of ₹100
  3. C)Profit of ₹180
  4. D)Loss of ₹100

Step-by-step solution

  1. Given Cost Price (CP) = ₹1200.
  2. Given Selling Price (SP) = ₹1380.
  3. Since SP > CP, there is a profit.
  4. Profit = SP - CP = ₹1380 - ₹1200 = ₹180.

Answer: Profit of ₹180

Example 3hard

A trader bought an article. He spent 10% of the cost price on transportation. Then, he sold it at a loss of 5% on the total cost. If the selling price was ₹1710, what was the original cost price of the article?
  1. A)₹1800
  2. B)₹1900
  3. C)₹2000
  4. D)₹1750

Step-by-step solution

  1. Let the original cost price be CP. Transportation cost = 10% of CP = 0.10 × CP.
  2. Total Cost Price (CP_total) = CP + 0.10 × CP = 1.10 × CP.
  3. Loss = 5% of CP_total = 0.05 × (1.10 × CP) = 0.055 × CP.
  4. Selling Price (SP) = CP_total - Loss = 1.10 × CP - 0.055 × CP = 1.045 × CP.
  5. Given SP = ₹1710. So, 1.045 × CP = ₹1710.
  6. CP = ₹1710 / 1.045 = ₹2000.

Answer: ₹2000
