The correct Answer is:
To find the selling price of a book after applying two successive discounts of 10% on its marked price of ₹900, we can follow these steps: ### Step 1: Calculate the first discount The first discount is 10% of the marked price. \[ \text{First Discount} = \frac{10}{100} \times 900 = 90 \] ### Step 2: Calculate the selling price after the first discount Subtract the first discount from the marked price to get the selling price after the first discount. \[ \text{Selling Price after First Discount} = 900 - 90 = 810 \] ### Step 3: Calculate the second discount Now, apply the second discount of 10% on the new selling price (₹810). \[ \text{Second Discount} = \frac{10}{100} \times 810 = 81 \] ### Step 4: Calculate the final selling price after the second discount Subtract the second discount from the selling price after the first discount. \[ \text{Final Selling Price} = 810 - 81 = 729 \] ### Conclusion The selling price of the book after giving two successive discounts of 10% each is ₹729. ---
