Ответ: С)

Answer 2

Calculation of Cost and Comparison

To determine which product is more cost-effective to produce from 15 kg of milk, we need to calculate the cost of producing both the 8% cottage cheese and the 10% cream.

Let's calculate the cost for each product:

1. 8% Cottage Cheese: - Price per kilogram: 600 Tenge - Percentage of milk used: 15 kg (100%) - Percentage of milk converted to cottage cheese: 8% - Amount of milk used for cottage cheese: 15 kg * 8% = 1.2 kg - Cost of producing 8% cottage cheese: 1.2 kg * 600 Tenge/kg = 720 Tenge

2. 10% Cream: - Price per kilogram: 320 Tenge - Percentage of milk used: 15 kg (100%) - Percentage of milk converted to cream: 10% - Amount of milk used for cream: 15 kg * 10% = 1.5 kg - Cost of producing 10% cream: 1.5 kg * 320 Tenge/kg = 480 Tenge

Comparison of Costs

Now, let's compare the costs of producing the two products:

- Cost of producing 8% cottage cheese: 720 Tenge - Cost of producing 10% cream: 480 Tenge

From the calculations, we can see that the cost of producing the 8% cottage cheese is 720 Tenge, while the cost of producing the 10% cream is 480 Tenge.

Conclusion

Therefore, in this case, the 10% cream is more cost-effective to produce from 15 kg of milk. The cost of producing the 10% cream is 240 Tenge less compared to the cost of producing the 8% cottage cheese.

So, the correct answer is E) 10% cream, by 240 Tenge.
