Correct Answer:
Option C —
The final price the customer pays is Rs. 450.
Step-by-Step Breakdown
1. Calculating the Discounted Price
The original price is Rupees 500.
A 20 percent discount on Rupees 500 equals Rupees 100.
Subtracting Rupees 100 from Rupees 500 leaves a discounted price of Rupees 400.
Statement A is correct.
2. Calculating the Sales Tax
A 12 percent sales tax is calculated on the discounted price of Rupees 400.
12 percent of Rupees 400 equals Rupees 48.
Statement B is correct.
3. Calculating the Final Price
Adding the tax of Rupees 48 to the discounted price of Rupees 400 gives a final price of Rupees 448.
Statement C claims the final price is Rupees 450, which is wrong.
Statement C is INCORRECT.
4. Comparing Final and Original Price
The final price of Rupees 448 is less than the original price of Rupees 500.
Statement D is correct.
