C Correct answer
Explanation

Let original price = 100. Bought at 5% discount = 95. Sold at 10% increase on 95 = 95 * 1.1 = 104.5. Profit on original = 104.5 - 100 = 4.5%.

AI explanation

Assume the original price is 100, so the trader's cost price after a 5% discount is 95. He sells the car for 10% more than his cost price, making the selling price 104.5. The profit on the original price is calculated as 104.5 minus 100, yielding 4.5. The profit percentage on the original price is 4.5%.
