Calculating the Price of 1kg of Cottage Cheese

To calculate the price of 1kg of cottage cheese, we can use the given information that 600g of oil and 1.4kg of cottage cheese were purchased for 103 rubles and 80 kopecks. Additionally, we know that 1kg of oil costs 75 rubles.

First, let's calculate the total cost of the oil and cottage cheese:

Total cost of 600g of oil: Using the given price of 1kg of oil, we can calculate the cost of 600g of oil.

Total cost of 1.4kg of cottage cheese: We'll calculate the cost of 1.4kg of cottage cheese based on the total cost of the oil and cottage cheese.

Then, we'll use the total cost of 1.4kg of cottage cheese to find the price of 1kg of cottage cheese.

Calculations

Total cost of 600g of oil: Using the given price of 1kg of oil, we can calculate the cost of 600g of oil. 600g = 0.6kg Cost of 0.6kg of oil = 0.6kg * 75 rubles/kg = 45 rubles

Total cost of 1.4kg of cottage cheese: Total cost = 103 rubles 80 kopecks Total cost of 1.4kg of cottage cheese = Total cost - Cost of 600g of oil Total cost of 1.4kg of cottage cheese = 103.80 - 45 = 58.80 rubles

Price of 1kg of cottage cheese: Price of 1kg of cottage cheese = Total cost of 1.4kg of cottage cheese / 1.4 Price of 1kg of cottage cheese = 58.80 / 1.4 = 42 rubles

Answer

The price of 1kg of cottage cheese is 42 rubles.
