The given pie chart shows the percentage distribution of a total of 2400 employees in different departments of a company. The given table shows the ratio of male to female employees in the different departments. What is the ratio of the number of female employees in the Production Department to that of the male employees in the IT Department?
Departments Male ∶ Female HR 3 ∶ 5 IT 2 ∶ 3 Accounts 3 ∶ 7 Marketing 7 ∶ 4 Production 5 ∶ 3
15 : 8
Calculation:
Female employees in production department = \(3\over8\) × 0.3 × 2400 = 270
Male employees in IT department = \(2\over5\) × 0.15 × 2400 = 144
Ratio = 270 : 144 = 15 : 8
∴ The required ratio is 15 : 8.
