The number of employees present in office E on Monday is what percent more than the number of employees present in office C on Thursday?

The correct answer is
53.33%

This question asks us to find the percentage by which the number of employees present in office E on Monday is more than the number of employees present in office C on Thursday. To solve this, we first need to extract the relevant attendance figures from the provided table.

Attendance Figures Extraction

  • Number of employees present in office E on Monday: From the table, we find the value at the intersection of the 'Monday' row and the 'E' column, which is 184.
  • Number of employees present in office C on Thursday: From the table, we find the value at the intersection of the 'Thursday' row and the 'C' column, which is 120.

Calculating the Percentage Increase

To find out how much more the attendance in office E on Monday is compared to office C on Thursday, we first calculate the difference in the number of employees. Then, we calculate this difference as a percentage of the attendance in office C on Thursday (the base value for comparison).

Step 1: Calculate the difference in attendance

Difference = (Employees in Office E on Monday) - (Employees in Office C on Thursday)

Difference = $184 - 120 = 64$

Step 2: Calculate the percentage increase

The formula for percentage increase is:

$$ \text{Percentage Increase} = \left( \frac{\text{Difference}}{\text{Original Value}} \right) \times 100 $$

Here, the Original Value is the number of employees present in office C on Thursday.

Percentage Increase = $ \left( \frac{64}{120} \right) \times 100 $

Now, we simplify the fraction:

Percentage Increase = $ \left( \frac{64}{120} \right) \times 100 = \left( \frac{8}{15} \right) \times 100 $

Percentage Increase = $ \frac{800}{15} $

Performing the division:

Percentage Increase = $ 53.333... \% $

Conclusion

The number of employees present in office E on Monday is approximately 53.33% more than the number of employees present in office C on Thursday. This matches option 4.
