Explanation:

- The cost price (CP) of the item is Rs2,000.

- The item is sold at a loss of 25%.

- To find the selling price (SP):

- Loss percentage is 25%, so the item is sold for 75% of its cost price.

- Calculate 75% of Rs2,000: $0.75\times 2000=1500$.

- Option 1: Rs1,500

- This is the correct selling price.

- Option 2: Rs1,000

- Too low for a 25% loss, as this indicates a 50% loss instead.

- Option 3: Rs2,000

- Means no loss or gain, which isn't the case here.

- Option 4: Rs3,500

- This indicates a profit, not applicable here.
