B Correct answer
Explanation

CP = 800. MP = 800 * 1.25 = 1000. Discount = 10% of 1000 = 100. SP = 900. Profit = 900 - 800 = 100. Profit % = (100/800) * 100 = 12.5%.

AI explanation

Using the net profit formula for successive percentage changes, x + y + (xy/100), the markup of 25 is x and the discount of -10 is y. The calculation is 25 - 10 + (25 * -10 / 100), which simplifies to 15 - 2.5. The result is 12.5%.
