Show answer & explanation
Correct answer: D
Key idea: split the 5 items into the group of 2 items (6% discount each) and the group of 3 items (12% discount each), compute discounts separately, then find the overall percentage.
Total marked price = 5 × 900 = 4500.
Discount on 2 items = 2 × 900 × 6% = 108.
Discount on 3 items = 3 × 900 × 12% = 324.
Total discount = 108 + 324 = 432.
Effective discount percentage = (432 / 4500) × 100 = 9.6%.
