Question

В трех цехах фабрики работают 740 человек .Число людей, работающих во втором цехе на 60 больше, чем в первом,и на 80 меньше ,чем в третьем . Сколько работает человек в каждом из этих цехов?

Answer 1

Пусть х людей во 2. цеху.
1-х-60
2- х. * фигурная скобка* 740
3- х+80

х+х-60+х+80=740
3х=720| : 3
х=240 (л)- в 1

240-60=180(л)- во 2

240+80= 320- в 3

Отвед: 240, 180, 320.

Answer 2

Calculation of the Number of Workers in Each Workshop

To determine the number of workers in each workshop, let's assign variables to represent the number of workers in the first, second, and third workshops.

Let: - x be the number of workers in the first workshop. - x + 60 be the number of workers in the second workshop (60 more than the first workshop). - x + 80 be the number of workers in the third workshop (80 less than the third workshop).

According to the given information, the total number of workers in all three workshops is 740.

Therefore, we can write the equation:

x + (x + 60) + (x + 80) = 740

Simplifying the equation:

3x + 140 = 740

Subtracting 140 from both sides:

3x = 600

Dividing both sides by 3:

x = 200

So, there are 200 workers in the first workshop.

The number of workers in the second workshop is x + 60 = 200 + 60 = 260 workers.

The number of workers in the third workshop is x + 80 = 200 + 80 = 280 workers.

Therefore, there are 200 workers in the first workshop, 260 workers in the second workshop, and 280 workers in the third workshop.
