Study the pie-chart and answer the question:

Total Number of Employees = 1400

If 80% of the number of employees working in the IT department and 40% of the number of employees working in both the HR and Accounts departments are females, then total number of female employees working in these three departments is .........

Total Number of Employees = 1400

The number of employees working in the IT department = $$1400 \times  \frac{72}{360} = 280$$

Number of females in the IT department = $$280 \times \frac{80}{100} = 224$$

The number of employees working in both the HR and Accounts departments = $$1400 \times \frac{(32.4 + 57.6)}{360} = 1400 \times \frac{90}{360} = 350$$

Number of females in both the HR and Accounts departments = $$350 \times \frac{40}{100} = 140$$

Total number of female employees working in these three departments = 224 + 140 = 364
