Answer 2

Task Analysis

The problem involves finding the prices of peaches and apricots given that the price of peaches is 20 rubles higher than the price of apricots. Additionally, 3 kg of peaches and 5 kg of apricots were purchased for a total of 620 rubles.

Solution

To solve the problem, we can use the following steps: 1. Set up an equation based on the given information. 2. Solve the equation to find the prices of peaches and apricots.

Equation Setup

Let's denote the price of apricots as x rubles per kilogram. Then, the price of peaches would be (x + 20) rubles per kilogram. The total cost of the purchase can be expressed as: \[3(x + 20) + 5x = 620\]

Solving the Equation

We can solve the equation to find the value of x and then calculate the price of peaches and apricots.

\[3(x + 20) + 5x = 620\] \[3x + 60 + 5x = 620\] \[8x + 60 = 620\] \[8x = 620 - 60\] \[8x = 560\] \[x = \frac{560}{8}\] \[x = 70\]

Calculation

The price of apricots (x) is 70 rubles per kilogram. Therefore, the price of peaches is (70 + 20) = 90 rubles per kilogram.

Answer

The price of apricots is 70 rubles per kilogram, and the price of peaches is 90 rubles per kilogram.
