Question

Школьники трех классов помогали в уборке картофеля. Один класс собрал 230 кг картофеля, а другой- на 20 кг меньше, чем первый, но оба класса собрали вместе на 40 кг меньше, чем третий класс. Сколько килограммов картофеля было собрано тремя классами?

Answer 1

1) 230-20=210(кг)- собрал 2 класс
2)230+210=440(кг)- собрали первый и второй класс вместе
3)440+40=480(кг)- собрал третий класс
4)230+210+480=920(кг)
Ответ: 3 класса вместе собрали 920 кг картофеля

Answer 2

230- 1 класс , 230-20= 210 - 2 класс , 230+210=440 - 1+2 класса , 440+40=480 - 3 класс , 230 + 210 + 480 = 920 - 1+2+3 класс

Answer 3

Calculation of the Total Weight of Potatoes Collected by Three Classes

To calculate the total weight of potatoes collected by the three classes, we need to analyze the information provided in the question.

According to the question, one class collected 230 kg of potatoes, while another class collected 20 kg less than the first class. Additionally, the combined weight of both classes is 40 kg less than the weight collected by the third class.

Let's break down the information:

- Weight collected by the first class: 230 kg- Weight collected by the second class: 20 kg less than the first class- Combined weight of both classes: 40 kg less than the third class To find the weight collected by the second class, we subtract 20 kg from the weight collected by the first class:

Weight collected by the second class = Weight collected by the first class - 20 kg

Now, let's calculate the total weight collected by the three classes:

Total weight collected by the three classes = Weight collected by the first class + Weight collected by the second class + Weight collected by the third class

Calculation Steps:

1. Weight collected by the second class = 230 kg - 20 kg = 210 kg 2. Total weight collected by the three classes = 230 kg + 210 kg + Weight collected by the third class

Unfortunately, the question does not provide the weight collected by the third class. Without this information, we cannot determine the exact total weight of potatoes collected by the three classes.

Please provide the weight collected by the third class so that we can calculate the total weight accurately.
