B Correct answer
Explanation

Profit = SP of 4 watches. Profit = SP - CP. SP of 4 = SP of 20 - CP of 20. CP of 20 = SP of 16. Profit % = (Profit / CP) * 100 = (SP of 4 / SP of 16) * 100 = (4/16) * 100 = 25%.

AI explanation

Using the formula for profit percentage when profit equals the selling price of y items out of x items sold, the profit percentage is (y divided by (x minus y)) multiplied by 100. Substituting the given values, we get (4 divided by (20 minus 4)) multiplied by 100. This simplifies to (4 divided by 16) multiplied by 100, resulting in a profit percentage of 25 percent.
