Purchase department has 24% of the total 4,500 employees, which is \( 0.24 \times 4500 = 1080 \) employees. The male to female ratio in Purchase is 1:1, so the 1,080 employees split evenly. Let's check the options:
Since Purchase splits its 1,080 employees equally between males and females, the number of females works out to exactly 540.
Therefore, the correct answer is 540.
IT department has 18% of the total 4,500 employees, which is \( 0.18 \times 4500 = 810 \). Accounts department has 11% of the total, which is \( 0.11 \times 4500 = 495 \). Let's check each option against their combined strength:
Since IT holds 810 employees and Accounts holds 495, their combined strength comes to exactly 1,305.
Therefore, the correct answer is 1,305.
Working out males and females department by department: IT has 540 males and 270 females (2:1 of 810); Marketing has 360 males and 540 females (2:3 of 900); HR has 450 males and 90 females (5:1 of 540); Production has 405 males and 270 females (3:2 of 675); Purchase has 540 males and 540 females (1:1 of 1,080); Accounts has 165 males and 330 females (1:2 of 495). Totalling these, males sum to \( 540+360+450+405+540+165 = 2460 \) and females sum to \( 270+540+90+270+540+330 = 2040 \). Let's check the options:
Simplifying the actual totals of 2,460 males and 2,040 females gives exactly 41:34.
Therefore, the correct answer is 41:34.
Marketing department has 20% of the total 4,500 employees, which is \( 0.20 \times 4500 = 900 \). With a male to female ratio of 2:3, females account for \( \frac{3}{5} \times 900 = 540 \). Let's check the options against this figure as a share of the total 4,500 employees:
Since Marketing has exactly 540 females out of 4,500 total employees, this works out to precisely 12%.
Therefore, the correct answer is 12%.
Marketing has 900 employees (20% of 4,500) with a male to female ratio of 2:3, giving \( \frac{2}{5} \times 900 = 360 \) males. HR has 540 employees (12% of 4,500) with a male to female ratio of 5:1, giving \( \frac{5}{6} \times 540 = 450 \) males. Let's check the options:
Simplifying the actual male counts of 360 in Marketing and 450 in HR gives exactly 4:5.
Therefore, the correct answer is 4:5.
