e correct answerThe cost of 25 items is the same as the revenue by selling X items. Find X, if the profit made in the transaction is 25%?

Let's break this down:

1. Let's assume the cost price of one item is C. Therefore, the cost price of 25 items is 25C.

2. The revenue from selling X items is also 25C.

3. The profit made in the transaction is 25%. This means that the selling price is 125% of the cost price. We can express this as 1.25C.

4. Since the revenue (which is the selling price times the number of items sold) is equal to the cost price of 25 items, we can set up the following equation:

   1.25C * X = 25C

5. To solve for X, we divide both sides of the equation by 1.25C:

   X = 25C / 1.25C

6. The C's cancel out, leaving us with:

   X = 25 / 1.25

7. Solving this gives us X = 20.

So, if the profit made in the transaction is 25%, 20 items need to be sold to generate the same revenue as the cost of 25 items.
