Problem Analysis

To solve this problem, we need to find the price per kilogram of radishes and cucumbers. We are given that the store sold 10 kg of radishes and 15 kg of cucumbers for a total of 680 UAH. Additionally, we are told that the price of cucumbers is 75% of the price of radishes.

Solution

Let's assume the price per kilogram of radishes is x UAH. Since the price of cucumbers is 75% of the price of radishes, the price per kilogram of cucumbers would be 0.75x UAH.

Now, we can calculate the total cost of radishes and cucumbers using the given information. The total cost of radishes would be 10 kg multiplied by x UAH per kilogram, and the total cost of cucumbers would be 15 kg multiplied by 0.75x UAH per kilogram. The sum of these two costs should be equal to 680 UAH.

Mathematically, we can represent this as an equation:

10x + 15(0.75x) = 680

Simplifying the equation:

10x + 11.25x = 680

21.25x = 680

Dividing both sides of the equation by 21.25:

x = 680 / 21.25

Calculating the value of x:

x ≈ 32

So, the price per kilogram of radishes is approximately 32 UAH.

Since the price of cucumbers is 75% of the price of radishes, the price per kilogram of cucumbers would be 0.75 * 32 UAH.

Calculating the value:

0.75 * 32 ≈ 24

So, the price per kilogram of cucumbers is approximately 24 UAH.

Answer

The price per kilogram of radishes is approximately 32 UAH, and the price per kilogram of cucumbers is approximately 24 UAH.
