Answer :

To find out whether Harinarayan made a profit or incurred a loss, we need to compare the purchase price of the laptop to the selling price. Here is the step-by-step solution:

1. Identify the purchase price: The amount Harinarayan paid to buy the laptop.
- Purchase Price = Rs. 65,000

2. Identify the selling price: The amount Harinarayan received when he sold the laptop.
- Selling Price = Rs. 50,000

3. Determine the difference: Subtract the selling price from the purchase price to find the difference.
- Difference = Purchase Price - Selling Price
- Difference = Rs. 65,000 - Rs. 50,000
- Difference = Rs. 15,000

4. Identify if it is a profit or a loss:
- If the purchase price is greater than the selling price, it is a loss.
- Since Rs. 65,000 (purchase price) is greater than Rs. 50,000 (selling price), Harinarayan incurred a loss.

5. State the loss amount:
- Loss = Rs. 15,000

Therefore, Harinarayan incurred a loss of Rs. 15,000 when he sold the laptop.
