A Correct answer
Explanation

Cost of 4 articles = Selling price of 3 articles. Let CP of 1 article be 1. CP of 4 = 4. SP of 3 = 4, so SP of 1 = 4/3. Profit = 4/3 - 1 = 1/3. Profit % = (1/3) / 1 * 100 = 33 1/3%.

AI explanation

Let the cost price of 4 articles be 4, making the cost price of 3 articles equal to 3. Since 3 articles are sold for the cost price of 4, the selling price is 4 and the profit is 1. Using the profit percentage formula, profit divided by cost price multiplied by 100 equals 1 divided by 3 multiplied by 100. This gives a profit percentage of 33 1/3 percent. The answer is 33 1/3 percent.
