C Correct answer
Explanation

Let initial fee = 1, visitors = 100. Revenue = 100. New fee = 0.75. New revenue = 120. New visitors = 120 / 0.75 = 160. Increase = 60%.

AI explanation

Assume the initial ticket price is Rs. 1 and the initial number of visitors is 100, making the initial total sale Rs. 100. The new ticket price after a 25% reduction is Rs. 0.75, and the new total sale after a 20% increase is Rs. 120. The new number of visitors is 120 / 0.75 = 160. The percentage increase in the number of visitors is ((160 - 100) / 100) * 100 = 60%. The percentage increase in visitors is 60%.
