Show answer & explanation
Correct answer: C
Solution: Calculate the final selling price after successive discounts on Rs. 800.
Step 1: Apply the 20% discount.
20% of 800 = 160, so price after first discount = 800 − 160 = 640.
Step 2: Apply the 10% discount on the reduced price.
10% of 640 = 64, so final price = 640 − 64 = 576.
Shortcut (single-step):
Multiply by the complements: 800 × 0.8 × 0.9 = 576.
Final selling price = Rs. 576.
