C Correct answer
Explanation

After successive discounts of 8%, 5% and 2%, the net discount factor is 0.92 × 0.95 × 0.98 = 0.85772. Selling price = 6423.90 = MP × 0.85772. Marked price = 6423.90/0.85772 = Rs.7500 (approximately). Working backwards: 7500 × 0.92 = 6900, 6900 × 0.95 = 6555, 6555 × 0.98 = 6423.90.
