A. 30
B. 28
C. 23

E. None of these

Number of employees working in the marketing department of Company B = 700
Total number of employees of Company B

= 750 + 500 + 700 + 350 + 200
= 2500
Required % = 700/2500 X 100 = 28%

Question 2: What is the respective ratio of the total number of employees working in the administrative departments of both companies to the total number of employees working in the Finance departments of both companies?

A. 2:3
B. 4:3
C. 3:2
D. 3:4
E. None of these

Total number of employees of administration in both companies
= 400 + 200 = 600
Total number employees of finance in both companies = 450 + 350 = 800

Question 3: The number of employees working in the HR department of Company A is approximately what percent of the number of employees working in the Finance department of Company B?

A. 44
B. 207
C. 53
D. 229
E. 198

Number of employees working in HR in Company A = 800

Number of employees working in IT of Company B after 20% increase = 750 X (120/100) = 900
Number of employees working in the administration of Company A = 400
Required difference = 900 – 400 = 500

Question 5: What is the difference between the average number of employees working in all the departments of Company A and the average number of employees working in the IT, Marketing, and Finance departments of Company B?
