Question

Шесть рабочих могут выполнить работу за 15 дней. За сколько дней выполнят эту работу 10 рабочих , если будут работать с такойже производительностью.

Answer 1

6   -  15
 10      x
10-15:6=25 дней 
1 зад 
---------------------------
52:1,3=40
40+52=92
нужно:92кг за15 дней и 10 рабочих за 15 дней все работуют с одинаковойю производиительности

Answer 2

6 рабочих = 15 дней
10 рабочих = х дней

$\frac{6}{10}$ = $\frac{x}{15}$
x = $\frac{6*15}{10}$ = $\frac{3*3}{1}$ 
x= 9

Answer 3

Calculation of Work Completion Time

To calculate the time it takes for 10 workers to complete the same job that 6 workers can do in 15 days, we can use the formula:

Total work = Number of workers × Time taken

Given that 6 workers can complete the work in 15 days, we can calculate the total work done by 6 workers in 1 day using the formula:

Total work = 6 workers × 15 days = 90 worker-days.

Now, to find out how many days it will take for 10 workers to complete the same work, we can use the formula:

Time taken = Total work ÷ Number of workers

Substituting the values, we get:

Time taken = 90 worker-days ÷ 10 workers = 9 days

Therefore, 10 workers will be able to complete the work in 9 days if they work with the same productivity as 6 workers.

I hope this helps! If you have any further questions, feel free to ask.
