Show answer & explanation
Correct answer: A
Key idea: Find each cost price from its selling price and percentage change, then compare total cost and total selling price.
For the mobile sold at 10% gain: CP = 9900 ÷ 1.10 = 9000.
For the mobile sold at 10% loss: CP = 9900 ÷ 0.90 = 11000.
Total cost price = 9000 + 11000 = 20000. Total selling price = 9900 + 9900 = 19800.
Net loss = 200. Percentage loss = (200 ÷ 20000) × 100 = 1%.
Answer: Loss of 1%.
