Explanation

Let's calculate the final selling price after two successive discounts of 10% and 5% on the marked price of Rs. 2000.

Step 1:

First discount = 10% of 2000 = 0.10 × 2000 = Rs. 200

Price after first discount = 2000 - 200 = Rs. 1800

Step 2:

Second discount = 5% of 1800 = 0.05 × 1800 = Rs. 90

Price after second discount = 1800 - 90 = Rs. 1710

Final selling price = Rs. 1710
