Explanation:

- The retailer wants to sell the item for Rs. 2,700 after a 10% discount.

- To find the marked price, let the marked price be 'x.'

- A 10% discount implies the customer pays 90% of the marked price.

- So, 90% of x = Rs. 2,700.

- This means \( 0.9 \times x = 2700 \).

- Solving for 'x':

\( x = \frac{2700}{0.9} \)

\( x = 3000 \).

- Check all options:

1. Rs. 2,850 - Not correct.

2. Rs. 3,000 - This is the correct marked price.

3. Rs. 3,050 - Not correct.

4. Rs. 3,110 - Not correct.
