Question : Study the pie chart and answer the question.
What percentage of employees of the company working in the Marketing department is more than the number of employees working in the IT department?
Option 1: 22
Option 2: 16.67
Option 3: 18.33
Option 4: 20
Correct Answer: 20
Solution :
Percentage gain = $\frac{\text{Difference in original value and final value}}{\text{Original value}}\times 100$%
Number of employees in the Marketing department (in degrees) = $86.4^\circ$
Number of employees in the IT department (in degrees) = $72^\circ$
Required percentage = $\frac{86.4^\circ\ -\ 72^\circ }{72^\circ}\times 100 = 20$%
Hence, the correct answer is 20.
