Question

Молоко даёт 25% сливок, сливки дают 20% масла. Сколько масла получится из молока, надоенного за 15 дней от 360 коров, если каждая корова в среднем даёт 15 кг молока в день?

Answer 1

15*15=225 (кг) молока даёт одна корова за 15 дней

225*360=81000 (кг) молока дают 360 коров за 15 дней

81000*0,25*0,2=4050 (кг) масла                             

                                                                                                                                 

                                                                                                                                   

Answer 2

15*15=225кг  молока дает 1 корова за 15 дней

225*360=81000 кг молока дают 360 коров за 15 дней

81000*0,25=20250 кг сливок

20250*0,2=4050 кг масла получится

Answer 3

Calculating the Amount of Butter from Milk

To calculate the amount of butter that can be obtained from the milk produced by 360 cows over 15 days, we can follow these steps:

1. Calculate the total amount of milk produced by all the cows over 15 days. 2. Determine the amount of cream in the milk. 3. Calculate the amount of butter that can be obtained from the cream.

Step 1: Calculate the Total Amount of Milk

Each cow produces an average of 15 kg of milk per day. Therefore, the total amount of milk produced by all 360 cows over 15 days can be calculated as follows: \[ \text{Total milk produced} = \text{Number of cows} \times \text{Milk produced per cow per day} \times \text{Number of days} \]

\[ \text{Total milk produced} = 360 \times 15 \times 15 \]

Step 2: Determine the Amount of Cream in the Milk

It is given that the milk gives 25% cream. Therefore, the amount of cream obtained from the milk can be calculated as: \[ \text{Cream obtained} = \frac{25}{100} \times \text{Total milk produced} \]

Step 3: Calculate the Amount of Butter

It is also given that the cream gives 20% butter. Therefore, the amount of butter obtained from the cream can be calculated as: \[ \text{Butter obtained} = \frac{20}{100} \times \text{Cream obtained} \]

Let's calculate the total amount of milk, the amount of cream, and the amount of butter obtained from the milk produced by 360 cows over 15 days.
