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

1)0,25*0,2=0,05 (5%) масла получается из молока

2)360*15*15=81000(кг)-молока получится от 360 коров за 15 дней

3)81000*0,05=4050(кг)-масла получится из 81000 кг молока

 

4050кг=4т 50кг

Answer 2

360х15х15=81000кг молока дают все коровы за 15 дней

25%:100%=0,25

81000х0,25=20250 кг сливок получится из этого молока

20%:100%=0,2

20250х0,2=4050 кг масла получится из молока

Answer 3

Calculation of Butter from Milk

To calculate the amount of butter that can be obtained from milk, we need to consider the following information:

- Milk contains 25% cream. - Cream contains 20% fat.

Given that each cow produces an average of 15 kg of milk per day, and there are 360 cows, we can calculate the total amount of milk produced in 15 days:

Total milk produced in 15 days = (15 kg/cow/day) * (360 cows) * (15 days) = 81,000 kg

To calculate the amount of cream in the milk, we multiply the total milk produced by the cream content:

Total cream = (25% cream) * (81,000 kg) = 20,250 kg

Finally, to calculate the amount of butter obtained from the cream, we multiply the total cream by the fat content:

Total butter = (20% fat) * (20,250 kg) = 4,050 kg

Therefore, if each cow produces an average of 15 kg of milk per day, and there are 360 cows, the total amount of butter obtained from the milk collected over 15 days would be approximately 4,050 kg.

Please note that the calculations provided are based on the given information and assumptions.
