1.Пусть х-мест в купе, тогда
3х-мест в плацкарте
3х+х=96
4х=96
х=96:4
х=24(м.)- в купе.
2. 24•3=72(м.)

Answer 2

Calculating the Number of Sleeping Berths in Different Train Cars

To calculate the number of sleeping berths in the compartment and open-plan cars, we can use the information provided in the question and the total number of sleeping berths in both cars.

Given: - The open-plan car has 3 times more sleeping berths than the compartment car. - The total number of sleeping berths in both cars is 96.

Let's denote: - x as the number of sleeping berths in the compartment car. - 3x as the number of sleeping berths in the open-plan car.

We can create the following equation based on the given information: x + 3x = 96

Solving for the Number of Sleeping Berths in Each Car

By solving the equation x + 3x = 96, we can find the number of sleeping berths in each car.

4x = 96

x = 96 / 4

x = 24

So, there are 24 sleeping berths in the compartment car and 3 * 24 = 72 sleeping berths in the open-plan car.

Therefore, there are 24 sleeping berths in the compartment car and 72 sleeping berths in the open-plan car.
