Question

В городе построен завод, на катором будут работать 840 рабочих следующих професий: токари, слесари, фрезеровщики. при этом токарей будет втрое, а слесарей вдвое больше,чем фрезеровщиков. Сколько токарей нужно для завода?

Answer 1

Фрезеровщиков приставим как х слесарей как 2х а токарей как 3х
х+2х+3х=840
6х=840
х=140
3*140=420 токарей

Answer 2

Calculation of the Number of Turners (Токари) Needed for the Factory

To determine the number of turners needed for the factory, we need to consider the given information that there will be three times as many turners as there are millers (фрезеровщики) and twice as many turners as there are locksmiths (слесари).

Let's assume the number of millers is represented by 'x'. Therefore, the number of locksmiths will be '2x', and the number of turners will be '3x'.

Given that the total number of workers is 840, we can set up the following equation to solve for 'x':

x + 2x + 3x = 840

Simplifying the equation:

6x = 840

Dividing both sides of the equation by 6:

x = 840 / 6

Calculating the value of 'x':

x = 140

Therefore, the number of turners needed for the factory is 3 times 'x', which is:

3 * 140 = 420.

So, the factory will need 420 turners.
