Question

В 1 бедоне было в 4 раза больше молока, чем во втором. Если из первого бедона вылить 30л, а во второй добавить 18 л., то в обоих бедонах будет одинаковое количество молока. Найдите, сколько молока было в двух бедонах изначально.

Answer 1

х+3х=х+х+20

4х=2х+20

4х-2х=20

2х=20

х=10 л (1)

10*3=30л  или 10+20=30л (2)

 

Ответ в одном 10л,а в другом 30л

Answer 2

Problem Analysis

We are given two containers, the first one containing 4 times more milk than the second one. If we pour out 30 liters from the first container and add 18 liters to the second container, the two containers will have the same amount of milk. We need to find the initial amount of milk in both containers.

Solution

Let's assume the initial amount of milk in the second container is x liters. Since the first container has 4 times more milk than the second container, the initial amount of milk in the first container is 4x liters.

After pouring out 30 liters from the first container, the amount of milk remaining in the first container is 4x - 30 liters. After adding 18 liters to the second container, the amount of milk in the second container becomes x + 18 liters.

According to the problem, the amount of milk in both containers is the same. Therefore, we can set up the following equation:

4x - 30 = x + 18

To solve this equation, we can simplify it:

4x - x = 18 + 30

3x = 48

x = 16

So, the initial amount of milk in the second container is 16 liters. Since the first container has 4 times more milk, the initial amount of milk in the first container is 4 * 16 = 64 liters.

Therefore, the initial amount of milk in the two containers was 64 liters in the first container and 16 liters in the second container.

Answer

The initial amount of milk in the first container was 64 liters, and the initial amount of milk in the second container was 16 liters.
