Question

Шесть маляров выполнят работу за 12 дней. За сколько дней выполнят эту же работу 8 маляров? Зарание Спасибо

Answer 1

Пусть работа равна x тогда x/6=12 => x=72
тогда 8 маляров выполнят эту работу за 72/8=9 дней

Answer 2

Problem Analysis

We are given that six painters can complete a job in 12 days. We need to determine how many days it would take for eight painters to complete the same job.

Solution

To solve this problem, we can use the concept of man-days. A man-day represents the amount of work one person can complete in one day.

Let's assume that the total work required to complete the job is represented by W. Since six painters can complete the job in 12 days, the total man-days required to complete the job is 6 * 12 = 72 man-days.

Now, we need to find out how many days it would take for eight painters to complete the same job. Let's represent the number of days required by D.

We can set up the following equation based on the concept of man-days:

8 * D = 72

Simplifying the equation, we find:

D = 72 / 8 = 9

Therefore, it would take eight painters 9 days to complete the same job.

Answer

Eight painters would be able to complete the same job in 9 days.
