Calculation of the Total Cost

To calculate the total cost of purchasing 2 kilograms of apples, we need to consider the prices of apples, bananas, and plums.

Given the following information: - The price of 1 kilogram of apples is 90 rubles. - The price of 1 kilogram of bananas is half the price of apples. - The price of 1 kilogram of plums is two-thirds the price of apples.

We can calculate the total cost as follows:

1. Calculate the cost of 1 kilogram of bananas: - Since the price of bananas is half the price of apples, the cost of 1 kilogram of bananas is 90 rubles / 2 = 45 rubles.

2. Calculate the cost of 1 kilogram of plums: - Since the price of plums is two-thirds the price of apples, the cost of 1 kilogram of plums is (2/3) * 90 rubles = 60 rubles.

3. Calculate the total cost of 2 kilograms of apples, 2 kilograms of bananas, and 2 kilograms of plums: - The cost of 2 kilograms of apples is 2 * 90 rubles = 180 rubles. - The cost of 2 kilograms of bananas is 2 * 45 rubles = 90 rubles. - The cost of 2 kilograms of plums is 2 * 60 rubles = 120 rubles.

Therefore, the total cost of purchasing 2 kilograms of apples, 2 kilograms of bananas, and 2 kilograms of plums is 180 rubles + 90 rubles + 120 rubles = 390 rubles.

Conclusion

To purchase 2 kilograms of apples, 2 kilograms of bananas, and 2 kilograms of plums, you would need to pay a total of 390 rubles.
