Calculation of the Average Price of Sold Apples

To calculate the average price of the apples sold by the farmer, we need to determine the total cost of the apples and divide it by the total weight of the apples.

The farmer sold 20 kg of apples at a price of 1.3 rubles per kilogram and 30 kg of apples at a price of 1.1 rubles per kilogram.

Let's calculate the total cost of the apples sold:

- For the 20 kg of apples sold at 1.3 rubles per kilogram: - Total cost = 20 kg * 1.3 rubles/kg = 26 rubles

- For the 30 kg of apples sold at 1.1 rubles per kilogram: - Total cost = 30 kg * 1.1 rubles/kg = 33 rubles

Now, let's calculate the total weight of the apples sold:

- Total weight = 20 kg + 30 kg = 50 kg

To find the average price per kilogram, we divide the total cost by the total weight:

- Average price = Total cost / Total weight = (26 rubles + 33 rubles) / 50 kg = 59 rubles / 50 kg = 1.18 rubles/kg

Therefore, the average price of the apples sold is 1.18 rubles per kilogram.

Please note that the calculations are based on the information provided and assume that the prices and weights are accurate.
