What is the total number of employees in the company?
Answer: D
The question provides the number of employees in the IT department, which can be used to find the total.
Number of employees in IT = 990.
From the pie chart, the percentage of employees in IT = 22%.
Let T be the total number of employees.
22% of T = 990
0.22 * T = 990
T = 990 / 0.22 = 4500.
The total number of employees is 4500.
