C Correct answer
Explanation

Let initial price be 100. After 20% increase, it is 120. After 25% increase, it is 120 * 1.25 = 150. To return to 100, the decrease required is 50. Percentage decrease = (50 / 150) * 100 = 33.33%.

AI explanation

Let the initial price be 100. The first increase of 20% makes the price 120, and the second increase of 25% makes the price 150. To bring the price back to 100, it must be reduced by 50. The required percentage decrease is 50 divided by 150, which is 33.33%.
