Explanation:

Let's break it down, step by step:

- Cost price is Rs 2,080.

- The trader marks it up by 25%. So, 25% of 2,080 is 520. That makes the marked price Rs 2,600.

- Now, there's a 15% discount on the marked price. 15% of 2,600 is 390.

- Subtract the discount: 2,600 - 390 = Rs 2,210.

- That means the final selling price is Rs 2,210.

Here's what that means for the options:

- Option 1 (Rs 2,392): Not correct, too high.

- Option 2 (Rs 2,600): That's the marked price, not the selling price.

- Option 3 (Rs 1,809): Too low, doesn't fit the calculation.

- Option 4 (Rs 2,210): This is the correct answer!
