Question

В автосалоне25 машин 3 видов : пежо ,рено,форд.Автомашины рено составляют 40% от числа машин пежо, а число автомашин форд составило 2/3 от числа машин рено.Сколько машин каждого вида?:)

Answer 1

Для решения задачи составим таблицу:

 

Пежо  -----  х машин

Рено   -----  0,4х=(2/5)х машин

Форд  -----  (2/3)*(2/5)х=(4/15)х машин

________________________________________

Всего:         25 машин

 

Составляем уравнение:

х+(2/5)х+(4/15)х=25 |*15

15х+6х+4х=375

25х=375

х=375:25

х=15(машин)-Пежо

(2\5)х=(2/5)*15=6(машин)-Рено

(4/15)*15=4(машины)-Форд

Answer 2

Calculation of the Number of Cars

To calculate the number of cars of each type (Peugeot, Renault, Ford), we can follow the given information:

- There are a total of 25 cars in the dealership. - Renault cars make up 40% of the total number of Peugeot cars. - The number of Ford cars is 2/3 of the total number of Renault cars.

Let's calculate the number of cars for each type step by step:

1. Calculate the number of Renault cars: - Let's assume the number of Peugeot cars is x. - Since Renault cars make up 40% of the total number of Peugeot cars, the number of Renault cars is 40% of x, which is 0.4x.

2. Calculate the number of Ford cars: - The number of Ford cars is 2/3 of the total number of Renault cars. - So, the number of Ford cars is (2/3) * (0.4x).

3. Calculate the number of Peugeot cars: - The total number of cars is 25. - Therefore, the number of Peugeot cars is 25 - (0.4x + (2/3) * (0.4x)).

Let's solve these equations to find the values:

1. Calculate the number of Renault cars: - The number of Renault cars is 0.4x.

2. Calculate the number of Ford cars: - The number of Ford cars is (2/3) * (0.4x).

3. Calculate the number of Peugeot cars: - The number of Peugeot cars is 25 - (0.4x + (2/3) * (0.4x)).

Let's solve these equations to find the values:

1. Calculate the number of Renault cars: - The number of Renault cars is 0.4x.

2. Calculate the number of Ford cars: - The number of Ford cars is (2/3) * (0.4x).

3. Calculate the number of Peugeot cars: - The number of Peugeot cars is 25 - (0.4x + (2/3) * (0.4x)).

Now, let's solve these equations to find the values:

1. Calculate the number of Renault cars: - The number of Renault cars is 0.4x.

2. Calculate the number of Ford cars: - The number of Ford cars is (2/3) * (0.4x).

3. Calculate the number of Peugeot cars: - The number of Peugeot cars is 25 - (0.4x + (2/3) * (0.4x)).

Now, let's solve these equations to find the values:

1. Calculate the number of Renault cars: - The number of Renault cars is 0.4x.

2. Calculate the number of Ford cars: - The number of Ford cars is (2/3) * (0.4x).
