Question

Молоко разлили в два бидона.Во втором бидоне молока было в два раза больше чем в первом.когда из каждого бидона вылили по 10 литров молока во втором бидоне осталось в три раза больше чем в первом.Сколько литров молока было в каждом бидоне?

Answer 1

                  Было     Вылили   Осталось

1 бидон       х л         10 л          х-10 (л)

2 бидон     2х л         10 л        (2х-10) (л)  -   в 3 р > чем в 1 бидоне

По условию задачи составляем уравнение:

(х-10)*3=2х-10

3х-30=2х-10

3х-2х = 30-10

х=20 (л)  - было молока в первом бидоне

2) 20*2 = 40 л молока было во втором бидоне изначально.

Answer 2

(х-10)*3=2х-10
3х-30=2х-10
3х-2х=20
х=20 литров молока было в первом бидоне
20*2=40литров во втором бидоне

Answer 3

Problem Analysis

We are given that milk was poured into two containers, and the second container had twice as much milk as the first container. After pouring out 10 liters of milk from each container, there was three times as much milk left in the second container as in the first container. We need to determine how much milk was initially in each container.

Solution

Let's assume that the amount of milk in the first container is x liters. According to the problem, the second container has twice as much milk as the first container, so the amount of milk in the second container is 2x liters.

After pouring out 10 liters of milk from each container, the second container has three times as much milk left as the first container. This means that the amount of milk left in the second container is 3 times (x - 10) liters, and the amount of milk left in the first container is x - 10 liters.

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

3 times (x - 10) = 2x - 10

Simplifying the equation:

3x - 30 = 2x - 10

3x - 2x = -10 + 30

x = 20

Therefore, there were initially 20 liters of milk in the first container and 40 liters of milk in the second container.

Answer

There were initially 20 liters of milk in the first container and 40 liters of milk in the second container.
