C Correct answer
Explanation

Let CP = 100. Initial SP = 110. New SP = 220. Profit = 220 - 100 = 120. Profit percentage = (120/100)*100 = 120%.

AI explanation

Let the cost price of the mobile phone be Rs. 100. A 10% profit means the initial selling price is Rs. 110. When the shopkeeper doubles this selling price, the new selling price becomes Rs. 220. Using the profit percentage formula, ((220 minus 100) divided by 100) multiplied by 100, the profit is 120%.
