Question

На первой ферме 400 коров,от которых надоивают в день на 6000 л молока больше, чем от 200 коров на второй ферме. найдите,сколько молока надоивают в день на первой ферме, учитывая, что удойность коровына на ей в среднем на 5 л больше,чем на второй ферме

Answer 1

 Пустьх -надой от коровы на второй ферме, тогда:

400*(х+5)=200*х+6000

400х+2000=200х+6000

400х-200х=6000-2000

200х=4000

х=20 литров надаивают от коровы на второй ферме

20+5=25 литров надаиват от коровы на первой ферме

 

 Ответ:от коровы на первой ферме надаивют 25 литров молока

Answer 2

Calculation of Milk Production on the First Farm

To find out how much milk is produced on the first farm, we need to compare the milk production of the two farms and take into account the difference in the average milk yield per cow.

Let's assume that the milk production on the second farm, with 200 cows, is X liters per day. According to the information given, the milk production on the first farm, with 400 cows, is 6000 liters more than on the second farm.

Therefore, the milk production on the first farm can be calculated as follows:

Milk production on the first farm = Milk production on the second farm + 6000 liters

Now, let's calculate the milk production on the first farm.

Milk production on the first farm = X + 6000 liters

Additionally, it is mentioned that the average milk yield per cow on the first farm is 5 liters more than on the second farm.

Therefore, the milk production on the first farm can also be calculated as follows:

Milk production on the first farm = (Average milk yield per cow on the second farm + 5 liters) * Number of cows on the first farm

Now, let's substitute the values and solve for X.

X + 6000 liters = (X + 5 liters) * 400 cows

To solve this equation, we can simplify it as follows:

X + 6000 = 400X + 2000

Simplifying further:

399X = 4000

X = 4000 / 399

X ≈ 10.03 liters

Therefore, the milk production on the first farm is approximately 10.03 liters per day.

Please note that the above calculation assumes that the milk production per cow is constant and does not take into account any other factors that may affect milk production on the farms.
