A Correct answer
Explanation

Cost price of 1 article = 25/15 = 5/3. Selling price of 1 article = 30/12 = 2.5. Profit = 2.5 - 5/3 = 7.5/3 - 5/3 = 2.5/3 = 5/6. Profit % = (Profit / CP) * 100 = (5/6) / (5/3) * 100 = (5/6) * (3/5) * 100 = 0.5 * 100 = 50%.

AI explanation

The cost price of one article is 25 divided by 15, which equals 5 divided by 3, and the selling price of one article is 30 divided by 12, which equals 5 divided by 2. Using the profit percentage formula, profit percent equals selling price minus cost price divided by cost price multiplied by 100, resulting in (1 divided by 6) divided by (5 divided by 3) multiplied by 100 to equal 50 percent. The result is 50 percent.
