This solution explains how to find the difference between the total number of employees present in specific offices on certain days, using the provided attendance data.

Attendance Data Overview

The table below shows the number of employees present on different weekdays across five offices: A, B, C, D, and E.

Calculating Total Attendance for C and D on Tuesday

First, we need to find the total number of employees present in offices C and D combined on Tuesday.

• Number of employees in Office C on Tuesday: 164
• Number of employees in Office D on Tuesday: 189

The total attendance is calculated as:

\text{Total}_{C,D,Tue} = \text{Attendance}_C + \text{Attendance}_D
\text{Total}_{C,D,Tue} = 164 + 189 = 353

Calculating Total Attendance for A and E on Thursday

Next, we find the total number of employees present in offices A and E combined on Thursday.

• Number of employees in Office A on Thursday: 89
• Number of employees in Office E on Thursday: 113

The total attendance is calculated as:

\text{Total}_{A,E,Thu} = \text{Attendance}_A + \text{Attendance}_E
\text{Total}_{A,E,Thu} = 89 + 113 = 202

Finding the Difference in Attendance

Finally, we calculate the difference between the two totals calculated above.

\text{Difference} = |\text{Total}_{C,D,Tue} - \text{Total}_{A,E,Thu}|
\text{Difference} = |353 - 202|
\text{Difference} = 151

Therefore, the difference between the total number of employees present in offices C and D together on Tuesday and the total number of employees present in offices A and E together on Thursday is 151.
