Question

В двух бидонах было 51 л молока.После того как из первого бидона отлили 16,2л,а из второго-7,2л,во втором бидоне молока оказалось в 4 раза больше,чем в первом.Сколько литров молока было в каждом бидоне первоначально?

Answer 1

16,2+7,2=23,4 л всего отлили
51-23,4 =27,6 л осталось в двух бидонах
осталось в первом х
осталось во втором 4х
составим уравнение
х+4х=27,6
5х=27,6
х=27,6:5
х=5,52 л осталось в первом
5,52+16,2=21,72 л было в первом
5,52*4=22,08 л осталось во втором
22,08+7,2=29,28 л было во втором
================================

Answer 2

Problem Analysis

We are given two containers with milk. After pouring out 16.2 liters from the first container and 7.2 liters from the second container, the amount of milk in the second container is four times greater than the amount in the first container. We need to determine the initial amount of milk in each container.

Solution

Let's assume that the initial amount of milk in the first container is x liters. Since we poured out 16.2 liters from the first container, the amount of milk remaining in the first container is x - 16.2 liters.

Similarly, let's assume that the initial amount of milk in the second container is y liters. After pouring out 7.2 liters from the second container, the amount of milk remaining in the second container is y - 7.2 liters.

According to the given information, the amount of milk in the second container is four times greater than the amount in the first container. Mathematically, we can represent this as:

(y - 7.2) = 4(x - 16.2)

Now, we can solve this equation to find the values of x and y.

Calculation

Let's solve the equation:

(y - 7.2) = 4(x - 16.2)

Expanding the equation:

y - 7.2 = 4x - 64.8

Rearranging the equation:

y = 4x - 57.6 + 7.2

y = 4x - 50.4

Now, we can substitute this value of y in terms of x into the equation (y - 7.2) = 4(x - 16.2):

(4x - 50.4 - 7.2) = 4(x - 16.2)

Simplifying the equation:

4x - 57.6 = 4x - 64.8

The 4x term cancels out on both sides:

-57.6 = -64.8

This equation is not possible to solve because it leads to a contradiction. Therefore, there is no solution to this problem.

Answer

There is no solution to this problem. The given information is contradictory, and it is not possible to determine the initial amount of milk in each container based on the provided information.
