Question

В гараже находилось 340 автомашин трех видов. Автомашины "Москвич2 составляли 45% от числа машин "Жигули", а число машин "Запорожец" составляли 5/9 от числа автомашин "Москвич". Сколько автомашин каждого вида находилось в гараже?

Answer 1

Пусть х машин марки "Жигули", 0,45х - марки "Москвич", 0,45х*5/9 = 0,25х - марки "Запорожец". Составим уравнение: х+0,45х+0,25х = 340 1,7х = 340 х = 340:1,7 х = 200 (м.)- марки "Жигули". 0,45*200= 90 (м.)- марки "Москвич". 0,25*200 = 50 (м.)- марки "Запорожец". 200+90+50 = 340 Ответ: 200 машин марки"Жигули", 90 машин марки "Москвич" и 50 машин марки "Запорожец". 

Answer 2

Calculation of the Number of Cars in the Garage

To determine the number of cars of each type in the garage, we can use the information provided in the question. Let's break it down step by step:

1. Total number of cars in the garage: 340.

2. Percentage of "Москвич" cars: 45% of the total number of cars.

3. Percentage of "Жигули" cars: The remaining cars after subtracting the "Москвич" cars.

4. Percentage of "Запорожец" cars: 5/9 of the number of "Москвич" cars.

Now, let's calculate the number of cars for each type:

1. Number of "Москвич" cars: - Percentage: 45% of 340 = 0.45 * 340 = 153 cars. (Source:

2. Number of "Жигули" cars: - Remaining cars: Total - "Москвич" = 340 - 153 = 187 cars.

3. Number of "Запорожец" cars: - Percentage: 5/9 of the number of "Москвич" cars. - Number of "Запорожец" cars: (5/9) * 153 = 85 cars.

Therefore, the number of cars of each type in the garage is as follows:

- "Москвич": 153 cars. - "Жигули": 187 cars. - "Запорожец": 85 cars.
