Question

A consulting company keeps 50 staff members in their local office between Monday and Friday, but only 15 on Saturday and Sunday. The average number of staff members in the office per day is _?_

Answer 1

The average number of staff members in the office per day is 40.

Explanation:

Number of staff on Monday = 50

Number of staff on Tuesday = 50

Number of staff on Wednesday = 50

Number of staff on Thursday = 50

Number of staff on Friday = 50

Number of staff on Saturday = 15

Number of staff on Sunday = 15

`Average=\frac{\text{sum of all values}}{\text{total numbers of terms}}`

Average of the staff member in the office per day:

`Average =(50+50+50+50+50+15+15)/(7)=40`

The average number of staff members in the office per day is 40.

Answer 2

40

Explanation:

The consulting company keeps 50 staff members in their local office between Monday and Friday.

Again it is given that the company keeps only 15 staff on Saturday and Sunday.

Therefore, the average number of staff members in the office per day will be
`\frac{\textrm{Total number of staff for all the days}}{\textrm{Total number of days}}`

=
`(50 + 50 + 50 + 50 + 50 + 15 + 15)/(7)`

=
`(280)/(7)`

= 40 (Answer)
