Calculation of the Prices of Apples and Apricots

To calculate the prices of apples and apricots, we can use the information provided in the question. It states that the price for 1 kg of apples is 3 times less than the price for 1 kg of apricots, and the total payment for the purchase was 100 rubles.

Let's assume the price for 1 kg of apples is x rubles, and the price for 1 kg of apricots is y rubles.

According to the given information, we can set up the following equations:

Equation 1: x = y/3 (the price for 1 kg of apples is 3 times less than the price for 1 kg of apricots) Equation 2: x + y = 100 (the total payment for the purchase was 100 rubles)

To solve this system of equations, we can substitute the value of x from Equation 1 into Equation 2:

y/3 + y = 100 4y/3 = 100 4y = 300 y = 75

Now, we can substitute the value of y back into Equation 1 to find the value of x:

x = 75/3 x = 25

Therefore, the price of apples is 25 rubles per kg and the price of apricots is 75 rubles per kg.

Please note that the above calculations are based on the information provided in the question and the assumption that the price for 1 kg of apples is 3 times less than the price for 1 kg of apricots.
