Question

Две бригады отделочников могут выполнить оклейку комнат за 12 дней при совместной работе первая бригада потратит 16 дней На оклейку комнат работая самостоятельно сколько дней необходимо второй бригаде на выполнение этой же работы при условии самостоятельной работы

Answer 1

1/12 – производительность  2-х бригад

1/16 -  производительность  первой бригады

1/12  - 1/16= 4/48 – 3/48= 1/48  производительность   второй  бригады

1:1/48 = 48  дней  понадобится второй  бригаде на выполнение этой же работы

Answer 2

Solution:

To solve this problem, we can use the concept of "work rates" to determine the time it takes for each brigade to complete the task individually.

Let's denote: - The work rate of the first brigade as R1 (rooms per day). - The work rate of the second brigade as R2 (rooms per day). - The total number of rooms to be wallpapered as T.

The combined work rate of both brigades is the sum of their individual work rates: R1 + R2 = 1/12 (rooms per day).

The individual work rate of the first brigade is: R1 = 1/16 (rooms per day).

We can solve for the work rate of the second brigade and then calculate the time it takes for the second brigade to complete the same task individually.

Calculation:

Using the given information and the work rate formula, we can calculate the work rate of the second brigade:

R1 + R2 = 1/12 1/16 + R2 = 1/12 R2 = 1/12 - 1/16 R2 = 1/48 (rooms per day).

Now, we can calculate the time it takes for the second brigade to complete the task individually:

T = 1/R2 T = 48 days.

So, the second brigade would take 48 days to complete the same task working independently.

Therefore, the second brigade would need 48 days to complete the same work if working independently.
