Calculation of the Price per Kilogram of Apples

To calculate the price per kilogram of apples, we can use the information provided in the question. Let's break down the given information:

- The mother bought 4 kg of apples and received 40 rubles in change. - If the mother had bought 6 kg of apples, she would have had to pay an additional 40 rubles.

To find the price per kilogram of apples, we can set up a proportion:

4 kg of apples / 40 rubles = 6 kg of apples / X rubles

To solve for X, we can cross-multiply and then divide:

4 kg * X rubles = 6 kg * 40 rubles

X = (6 kg * 40 rubles) / 4 kg

Now, let's calculate the value of X:

X = (240 rubles) / 4 kg

X = 60 rubles per kilogram

Therefore, the price per kilogram of apples is 60 rubles.
