Problem Analysis

To solve this problem, we need to determine the cost of one pastry. We are given that the mother bought 4 pastries and received 40 rubles in change. Additionally, if she had bought 6 pastries, she would have had to pay an additional 40 rubles.

Let's assume the cost of one pastry is x rubles.

Solution

To find the cost of one pastry, we can set up an equation based on the given information.

1. The cost of 4 pastries plus 40 rubles in change is equal to the total amount paid: ``` 4x + 40 = 4x ```

2. The cost of 6 pastries plus 40 rubles is equal to the total amount paid: ``` 6x + 40 = 6x ```

By comparing these two equations, we can see that they are contradictory. There is no solution that satisfies both equations. This means that the given information is inconsistent or there may be an error in the problem statement.

Unfortunately, without additional information or clarification, we cannot determine the cost of one pastry.
