Question

Молоко разлили в 2 бидона.во втором больше в 2 раза.когда из бидонов вылили по 10 л молока,то осталось в 3 раза больше чем в первом.сколько было молока в каждом бидоне?

Answer 1

Х - в первом было
2х - во втором было
х-10 - в первом стало
2х-10 - во втором стало
3(х-10)=2х-10
3х-30=2х-10
3х-2х=30-10
х=20 (л) - в первом было
2х=20*2=40 (л) во втором было
Ответ: в первом бидоне было 20 л молока, во втором - 40 л

Answer 2

Problem Analysis

We are given that milk was poured into two containers, with the second container having twice as much milk as the first. When 10 liters of milk were poured out of each container, the amount of milk remaining in the second container was three times the amount remaining in the first container. We need to determine the initial amount of milk in each container.

Solution

Let's assume the initial amount of milk in the first container is x liters. Since the second container has twice as much milk as the first, the initial amount of milk in the second container is 2x liters.

When 10 liters of milk are poured out of each container, the amount of milk remaining in the first container is x - 10 liters, and the amount of milk remaining in the second container is 2x - 10 liters.

According to the problem, the amount of milk remaining in the second container is three times the amount remaining in the first container:

2x - 10 = 3(x - 10)

Let's solve this equation to find the value of x:

2x - 10 = 3x - 30

-x = -20

x = 20

Therefore, the initial amount of milk in the first container is 20 liters, and the initial amount of milk in the second container is 2 * 20 = 40 liters.

Answer

The initial amount of milk in each container was 20 liters and 40 liters respectively.
