Answer 1

Problem Analysis

We are given that there are two bags of grain. The weight of the grain in these two bags is 4 centners (400 kilograms) and 20 kilograms less than the weight of the grain in seven bags of the same kind. We need to find the total weight of the grain in these bags.

Solution

Let's assume the weight of the grain in each bag is x kilograms. According to the problem, the weight of the grain in the two bags is 4 centners (400 kilograms) and 20 kilograms less than the weight of the grain in seven bags.

We can set up the following equation to represent the given information:

2x = 7x - 20

Simplifying the equation, we get:

7x - 2x = 20

5x = 20

Dividing both sides of the equation by 5, we find:

x = 4

Therefore, the weight of the grain in each bag is 4 kilograms.

To find the total weight of the grain in these bags, we multiply the weight of each bag by the number of bags:

Total weight = 2 bags * 4 kilograms/bag = 8 kilograms

So, the total weight of the grain in these bags is 8 kilograms.

Answer

The total weight of the grain in the two bags is 8 kilograms.
