Types of Questions in Profit and Loss for Competitive Exams

The Profit and Loss section in competitive exams tests a candidate’s ability to analyze and calculate financial transactions involving the buying and selling of goods. Here are some common types of questions that you might encounter in exams like the SSC CGL:

1. Basic Profit and Loss Calculation

These questions require calculating the straightforward profit or loss from a transaction.

Example: If a shopkeeper buys an item for $200 and sells it for $250, what is the profit and the profit percentage?

2. Finding Selling Price or Cost Price

In these questions, you might be given the profit or loss amount and the profit or loss percentage, and you need to find either the selling price or the cost price.

Example: A man sells a laptop for $660, making a profit of 10%. At what price did he buy the laptop?

3. Successive Selling

These involve multiple buying and selling transactions, often requiring the calculation of overall profit or loss after several successive sales.

Example: A trader buys goods for $1,000, sells one-third of the goods at a loss of 5%, and sells the rest at a profit of 15%. What is the total profit or loss?

4. Discount and Marked Price

These questions deal with scenarios where goods are sold at a discount on the marked price. Candidates need to calculate the selling price after discount or find the marked price given the discount rate and selling price.

Example: An item is marked at $500 and sold at a discount of 20%. What is the selling price?

5. Using False Weights

These involve calculating profit or loss when a seller uses false weights, thereby cheating in measuring.

Example: A shopkeeper sells his goods at cost price but uses a weight of 800 grams instead of 1 kilogram. Calculate his profit percentage.

6. Break-even Points

Questions may ask for the quantity or price at which selling will neither result in a profit nor a loss.

Example: If selling 100 units results in a profit of $100 and selling 120 units results in a loss of $100, find the break-even point.

7. Commission and Brokerage

These questions focus on transactions where a commission or brokerage fee is involved, affecting the overall profit or loss.

Example: If a broker sells your house for $200,000 and charges a 1% commission, how much do you get after the commission is deducted?
