Study the pie-chart and answer the question.

The total number of employees of the company in offices D and E is what percentage more than the number of employees in office A? (Your answer should be correct to one decimal place.)

21.4

Employees in D & E together = 57.6º + 64.8º = 122.4º

Employees in A = 100.8º

Required percentage = \(\frac{122.4º - 100.8º}{100.8º}\) × 100

= \(\frac{21.6º}{100.8º}\) × 100

= 21.4%
