Question

После того как дима перелил из одного бидона 12,5% находившегося в нём молока в другой то молока в 2 бидонах стало по ровну по 35 литров сколько молока во втором бидоне было первоначально

Answer 1

Пусть 1 бидон - х, тогда 2 бидон -    70-х
1 бидон = х-0,125х=0,875х
2 бидон = 70 - х=0,125
70-х+0,125=0.875
x=40 - 1бидон
70-40=30 - 2 бидон

Answer 2

Problem Analysis

We are given that after transferring 12.5% of the milk from one container to another, the two containers have an equal amount of milk, which is 35 liters each. We need to determine the initial amount of milk in the second container.

Solution

Let's assume that the initial amount of milk in the second container was x liters.

According to the problem, 12.5% of the milk from the first container was transferred to the second container. This means that the remaining milk in the first container is 87.5% of its initial amount.

We can set up the following equation to represent the situation:

0.875 * (initial amount of milk in the first container) = x + 35

Simplifying the equation, we have:

0.875 * (initial amount of milk in the first container) = x + 35

To solve for the initial amount of milk in the first container, we can rearrange the equation as follows:

(initial amount of milk in the first container) = (x + 35) / 0.875

Now, we can substitute the given information that the initial amount of milk in the second container is equal to the initial amount of milk in the first container:

(initial amount of milk in the second container) = (x + 35) / 0.875

Let's calculate the initial amount of milk in the second container using this equation.

Calculation

Using the equation (initial amount of milk in the second container) = (x + 35) / 0.875, we can substitute the value of 35 for the initial amount of milk in the second container:

(initial amount of milk in the second container) = (x + 35) / 0.875 = 35

Solving for x, we have:

x + 35 = 35 * 0.875

x + 35 = 30.625

x = 30.625 - 35

x = -4.375

Since the amount of milk cannot be negative, we can conclude that there was no milk initially in the second container.

Answer

The initial amount of milk in the second container was 0 liters.
