Explanation:

To determine the percentage of discount, follow these steps:

- Marked Price: Rs. 2,300

- Selling Price: Rs. 2,024

- Discount Amount: Rs. 2,300 - Rs. 2,024 = Rs. 276

- Discount Percentage Formula: (Discount Amount / Marked Price) × 100

Now, let's calculate:

- Discount Percentage: (276 / 2300) × 100 ˜ 12%

- Option 1: 13% - This option is slightly higher than the actual discount percentage.

- Option 2: 10% - This is lower than the actual discount percentage.

- Option 3: 12% - This exactly matches the calculated discount percentage.

- Option 4: 11% - This is slightly less than the actual discount percentage.
