Problem Analysis

To solve this problem, we need to determine the amount of grain brought in each week. We are given that in the first week, 4 identical bags of grain were brought, and in the second week, 5 identical bags of grain were brought. In total, 540 kg of grain was brought over the two weeks. We need to find the amount of grain brought in each week.

Solution

Let's assume that the amount of grain brought in each week is x kg.

According to the given information, in the first week, 4 identical bags of grain were brought. Since each bag contains x kg of grain, the total amount of grain brought in the first week is 4x kg.

Similarly, in the second week, 5 identical bags of grain were brought, resulting in a total of 5x kg of grain.

Adding the amounts of grain brought in both weeks, we have: 4x + 5x = 540 kg

Simplifying the equation, we get: 9x = 540 kg

To find the value of x, we divide both sides of the equation by 9: x = 540 kg / 9 x = 60 kg

Therefore, each week, 60 kg of grain was brought.

Answer

Each week, 60 kilograms of grain were brought.
