Calculation of the Total Cost

To calculate the total cost of purchasing 2 kg of apples, 3 kg of bananas, and 2 kg of plums, we need to know the prices per kilogram of each fruit.

Given the information provided, we know that 1 kg of apples costs 90 rubles, 1 kg of bananas costs half the price of apples, and 1 kg of plums costs two-thirds the price of apples.

Let's break down the calculation step by step:

1. The cost of 2 kg of apples is calculated by multiplying the price per kilogram of apples (90 rubles) by the weight (2 kg): - Cost of 2 kg of apples = 90 rubles/kg * 2 kg = 180 rubles.

2. The cost of 3 kg of bananas is calculated by multiplying the price per kilogram of bananas (half the price of apples) by the weight (3 kg): - Price per kilogram of bananas = 90 rubles/kg / 2 = 45 rubles/kg. - Cost of 3 kg of bananas = 45 rubles/kg * 3 kg = 135 rubles.

3. The cost of 2 kg of plums is calculated by multiplying the price per kilogram of plums (two-thirds the price of apples) by the weight (2 kg): - Price per kilogram of plums = 90 rubles/kg * (2/3) = 60 rubles/kg. - Cost of 2 kg of plums = 60 rubles/kg * 2 kg = 120 rubles.

Finally, to find the total cost, we add up the costs of each fruit: - Total cost = Cost of 2 kg of apples + Cost of 3 kg of bananas + Cost of 2 kg of plums - Total cost = 180 rubles + 135 rubles + 120 rubles = 435 rubles.

Therefore, the total cost of purchasing 2 kg of apples, 3 kg of bananas, and 2 kg of plums is 435 rubles.
