A Correct answer
Explanation

CP of 25 = SP of m. Profit = 25%. SP = 1.25 * CP. CP of 25 = 1.25 * CP of m. 25 = 1.25 * m. m = 25 / 1.25 = 20.

AI explanation

Using the formula for profit percentage, Profit% equals ((Cost Price of m - Selling Price of m) / Selling Price of m) times 100. Since the selling price of m articles equals the cost price of 25 articles, we have 25 = m times 1.25. Solving for m gives a value of 20.
