Question

В трех цехах было 2400 работников. В первом цехе было на 130 рабочих меньше, чем во втором и на 160 рабочих больше , чем в третьем. Сколько рабочих было в каждом цехе? ПОЖАЛУЙСТА ПОМОГИТЕ! ОЧЕНЬ НАДО, НЕ МОГУ РЕШИТЬ...

Answer 1

В первом цеху-на 160 р. больше чем в третьем.
Во втором ц.-на 130 р. больше чем в первом.
В третьем ц.-x р.
В первом- x+160
Во втором 130+(x+160)
В третьем- х
Составляем уравнение:
x+x+160+130(x+160)=2400
2x+290+x+160=2400
3x+450=2400
3x=2400-450
3x=1950
x=650            
Ответ: 650 работников в третьем цеху.
В первом: 650+160=810 работников.
Во втором:810+130=940 работников.
Ответ: 650,810 и 940 работников.

Answer 2

Problem Analysis

We are given information about three workshops and the total number of workers in those workshops. We also know that the first workshop has 130 fewer workers than the second workshop and 160 more workers than the third workshop. We need to determine the number of workers in each workshop.

Solution

Let's assume the number of workers in the second workshop is x.

According to the given information: - The first workshop has 130 fewer workers than the second workshop, so the number of workers in the first workshop is x - 130. - The first workshop has 160 more workers than the third workshop, so the number of workers in the third workshop is x - 160.

We can now set up an equation to solve for x:

(x - 130) + x + (x - 160) = 2400

Simplifying the equation:

3x - 290 = 2400

3x = 2690

x = 2690 / 3

x ≈ 896.67

Since the number of workers must be a whole number, we can round x to the nearest whole number. Therefore, the number of workers in the second workshop is approximately 897.

Now, we can calculate the number of workers in the first and third workshops:

- The number of workers in the first workshop is x - 130 ≈ 897 - 130 = 767. - The number of workers in the third workshop is x - 160 ≈ 897 - 160 = 737.

Answer

Therefore, there were approximately 767 workers in the first workshop, 897 workers in the second workshop, and 737 workers in the third workshop.
