Explanation:

- Cost price calculation:

- Pen: Rs600

- Notebook: Rs4,000

- Sell price calculation:

- Pen with a 20% loss: 600 - 20% of 600 = Rs480

- Notebook with a 32% loss: 4000 - 32% of 4000 = Rs2,720

- Total cost:

- Rs600 (pen) + Rs4,000 (notebook) = Rs4,600

- Total sell price:

- Rs480 + Rs2,720 = Rs3,200

- Total loss:

- Rs4,600 - Rs3,200 = Rs1,400

- Percentage of total loss:

- (1,400 / 4,600) * 100 = 30.43%

- Correct Answer: Option 3 - 30.43%
