Problem Analysis

Tolya bought 1.2 kg of pears, Vasya bought 2.3 kg of pears, and the total cost was 96 kopeks. We need to find out how much Vika bought and the price per kilogram.

Solution

Let's assume that Vika bought x kilograms of pears. The total weight of pears bought by all three is the sum of their individual weights:

1.2 kg + 2.3 kg + x kg = total weight

The total cost of the pears is given as 96 kopeks. We can set up the following equation to represent the relationship between the weight and cost:

1.2 kg * price per kilogram + 2.3 kg * price per kilogram + x kg * price per kilogram = 96 kopeks

Now we have two equations with two unknowns. We can solve this system of equations to find the values of x (the weight Vika bought) and the price per kilogram.

Calculation

Let's solve the system of equations:

1.2 kg + 2.3 kg + x kg = total weight 1.2 kg * price per kilogram + 2.3 kg * price per kilogram + x kg * price per kilogram = 96 kopeks

Substituting the known values:

1.2 kg + 2.3 kg + x kg = total weight 1.2 kg * price per kilogram + 2.3 kg * price per kilogram + x kg * price per kilogram = 96 kopeks

Simplifying the equations:

3.5 kg + x kg = total weight (1.2 kg + 2.3 kg + x kg) * price per kilogram = 96 kopeks

Substituting the value of total weight:

3.5 kg + x kg = total weight (3.5 kg + x kg) * price per kilogram = 96 kopeks

Now we have a system of equations with one unknown. We can solve for x and the price per kilogram.

Solution

Let's solve the system of equations:

3.5 kg + x kg = total weight (3.5 kg + x kg) * price per kilogram = 96 kopeks

Substituting the value of total weight:

3.5 kg + x kg = total weight (3.5 kg + x kg) * price per kilogram = 96 kopeks

Simplifying the equations:

3.5 kg + x kg = total weight 3.5 kg * price per kilogram + x kg * price per kilogram = 96 kopeks

Since the total weight is not given, we cannot solve for x and the price per kilogram without additional information.

Please provide the total weight or any other relevant information to solve the problem.
