Study the following pie chart and answer the question given below. Number of employees in department E = 216 The ratio of the number of male and female employees in department C is 4 : 5, and in department A 45% of the employees are male. What is the difference between the number of female employees in department C and the number of male employees in department A?
18
Calculation:
According to the chart-
Department E has 12% or 216 employees.
∴ Total number of employees = \(216\over12\) × 100 = 1800
Number of female employees in Department C = \(5\over9\) × \(18\over100\) × 1800 = 180
Number of male employees in Department A = 0.45 × \(20\over100\) × 1800 = 162
Difference = 180 - 162 = 18
∴ The net difference in the number of employee is 18.
