Question

В магазин поступил кофе упакованный в три мешка.Когда из первого мешка в третий переложили 21 кг 125 г,а из второго в третий 11 кг 115 г то в каждом мешке оказалось по 40 кг кофе. Сколько кофе было в каждом мешке первоначально. с решением Пожалуйста

Answer 1

21.125 +11.115 = 32.235 это стало  в третем 
40-32.235=

Answer 2

1)40кг+19кг 125г=59кг 125г(первый мешок)
2)40кг+11кг 115г=51кг 115г(второй мешок)
3)40кг-(19кг 125г+11кг 115г)=9кг 760г(третий мешок)

Answer 3

Problem Analysis

We are given that coffee is packaged in three bags. When 21 kg 125 g of coffee is transferred from the first bag to the third bag, and 11 kg 115 g of coffee is transferred from the second bag to the third bag, each bag ends up containing 40 kg of coffee. We need to determine the initial amount of coffee in each bag.

Solution

Let's assume that the initial amount of coffee in the first bag is x kg, in the second bag is y kg, and in the third bag is z kg.

According to the given information, when 21 kg 125 g of coffee is transferred from the first bag to the third bag, the third bag now contains z + 21.125 kg of coffee. Similarly, when 11 kg 115 g of coffee is transferred from the second bag to the third bag, the third bag now contains z + 21.125 + 11.115 kg of coffee.

Since the third bag ends up containing 40 kg of coffee, we can set up the following equation:

z + 21.125 + 11.115 = 40

Simplifying the equation, we get:

z = 40 - 21.125 - 11.115

Now, we can substitute the value of z back into the equation to find the initial amounts of coffee in the first and second bags.

Let's calculate the solution.

Calculation

Substituting the value of z into the equation:

z = 40 - 21.125 - 11.115

z = 40 - 32.24

z = 7.76

So, the initial amount of coffee in the third bag (z) is 7.76 kg.

Now, we can calculate the initial amounts of coffee in the first and second bags.

From the given information, we know that each bag initially contained 40 kg of coffee. Therefore, the initial amount of coffee in the first and second bags is also 40 kg.

Answer

The initial amount of coffee in each bag was: - First bag: 40 kg - Second bag: 40 kg - Third bag: 7.76 kg
