Calculating the Cost of Onions

To calculate the cost of onions, we can use the fact that the owner bought 5kg of carrots for 40 rubles. Since the carrots and onions were bought at the same price, we can use this information to find the cost of the onions.

Step 1: Calculate the cost per kilogram of carrots. - Cost of 5kg of carrots = 40 rubles - Cost per kilogram of carrots = 40 rubles / 5kg = 8 rubles/kg

Step 2: Use the cost per kilogram of carrots to find the cost of 2kg of onions. - Cost of 2kg of onions = Cost per kilogram of carrots * 2kg

Step 3: Calculate the total cost of the onions. - Total cost of onions = Cost of 2kg of onions

Step 4: Provide the final answer.

The cost of onions is calculated as follows: - Cost per kilogram of carrots = 8 rubles/kg - Cost of 2kg of onions = 8 rubles/kg * 2kg = 16 rubles

Therefore, the owner paid 16 rubles for the 2kg of onions.
