C Correct answer
Explanation

Let CP of 1 table be 1. CP of 15 tables = 15. SP of 20 tables = 15. SP of 1 table = 15/20 = 0.75. Loss = 1 - 0.75 = 0.25. Loss % = (0.25/1) * 100 = 25%.

AI explanation

Let the cost price of one table be CP and the selling price be SP. We are given 15CP = 20SP, so the ratio of SP to CP is 15/20 or 3/4. The loss percentage formula is ((CP - SP)/CP) * 100. The loss is (1 - 3/4) * 100 = 25%.
