What is the total number of male employees in the company?
Answer: B
Correct answer: 2280
The IT department is 22% of the workforce and holds 990 people, so the company total is
\[\frac{990}{0.22} = 4500\]
Apply each department’s percentage, then split it by the male:female ratio.
HR, 12% of 4500 = 540, ratio 1:2, males \(= \tfrac{1}{3}\times 540 = 180\).
Accounts, 18% = 810, ratio 4:5, males \(= \tfrac{4}{9}\times 810 = 360\).
Production, 28% = 1260, ratio 11:7, males \(= \tfrac{11}{18}\times 1260 = 770\).
IT, 22% = 990, ratio 5:4, males \(= \tfrac{5}{9}\times 990 = 550\).
Marketing, 20% = 900, ratio 7:8, males \(= \tfrac{7}{15}\times 900 = 420\).
\[180 + 360 + 770 + 550 + 420 = 2280\]
The remaining 2220 employees are female, and the two figures add back to 4500.
