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 _____.

364

40% = \(\frac{2}{5}\)  & 80% =  \(\frac{4}{5}\) 

Number of females in IT = \(\frac{4}{5}\) ×\(\frac{72}{360}\) × 1400 = 224

Number of females in HR & account = \(\frac{2}{5}\) ×\(\frac{57.6 + 32.4}{360}\) × 1400

= 140

Total number of females in all three department = 224 + 140 = 364
