I've been here too long

8.5 hour x 12 lines x 8 persons per hour= 816

X= 8 1/2 * 12 * 8

8 1/2 = working hours

In 1 hour 1 line process 8 people. So, in 1 hour 12 line process people = 12X8 =96 So, in 8.5 hour people process by 12 lines = 96X8.5 answer = 816

16:30 - 8:00 = 8,5 h

8 pessoas/h * 8,5 h * 12 = 816

The time between 8 am and 4:30 pm is 8 hours 30 minutes, or 8 1/2 hours. Since the 12 lines process 8 people an hour, 96 people are processed each hour. So, 96 is multiplied by 8 1/2 to give the number processed each day, which is 816.

To get people processed in a working day, first find the time of work 16:30-8:00=8 1/2 hours Since each hour, they process 8 persons with 12 lines that are open = 8 1/2 * 12 * 8 =816 people

The Department is open from $8 am$ to $4:30 pm$ i.e., for $8$ and $1/2$ hours.

Now, there are $12$ lines and each line can process $8$ people in an hour. This means that it can process ( $8 \times 12$ = ) $96$ people in an hour.

So, in $8$ and $1/2$ hours, it can process ( $8.5 \times 96$ = ) $816$ people.

There are 12 lines and each line can process 8 people in an hour. 8 * 12=96

They can process 96 people an hour. There are 8 and a half hours in a working day.

8.5 * 96=816

816 people can be processed in one working day.
