Один класс собрал 230 кг картофеля, другой-на 20 кг больше, чем первый, но оба класса собрали вместе на 40 кг меньше, чем третий класс. Сколько килограммов картофеля было собрано тремя классами?

Answer 1

230 +(230+20)+(230+230+20+40)= 1000 картофеля

Answer 2

Problem Analysis

To solve this problem, we need to find the total weight of potatoes collected by three classes. We are given the following information: - One class collected 230 kg of potatoes. - Another class collected 20 kg more than the first class. - The combined weight of both classes is 40 kg less than the third class.

Let's solve this step by step.

Solution

Let's assume the weight of potatoes collected by the first class is x kg.

According to the problem, the second class collected 20 kg more than the first class. So, the weight of potatoes collected by the second class is x + 20 kg.

The combined weight of both classes is 40 kg less than the third class. So, the weight of potatoes collected by the third class is (x + x + 20) + 40 = 2x + 60 kg.

Now, we can set up an equation to solve for x:

x + (x + 20) = 2x + 60

Simplifying the equation:

2x + 20 = 2x + 60

Subtracting 2x from both sides:

20 = 60

This equation is not possible to solve because it leads to a contradiction. It means there is no solution that satisfies the given conditions.

Therefore, we cannot determine the total weight of potatoes collected by the three classes based on the information provided.

Conclusion

Based on the given information, it is not possible to determine the total weight of potatoes collected by the three classes.
