A Correct answer
Explanation

Cost of 25 = Selling price of 20. Let CP be cost per watch and SP be selling price per watch. 25*CP = 20*SP, so SP/CP = 25/20 = 1.25. This represents a 25% profit.

AI explanation

Using the profit percentage formula when cost price and selling price units are equal, Profit% = ((Number of Items Sold - Number of Items Bought) / Number of Items Bought) * 100. Substituting the values gives ((25 - 20) / 20) * 100, which equals (5 / 20) * 100. This results in a 25% profit.
