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 _____.
Answer & explanation
Correct answer: option 4
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
