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.)

As per the given data in the question,

Total number of employee=9200

Total number of employee in the office D $$=\dfrac{9200\times 57.6^\circ}{360}=1656$$

Total number of employee in the office E $$=\dfrac{9200\times 64.8^\circ}{360}=1472$$

Total number of employee in the office A $$=\dfrac{9200\times 100.8^\circ}{360}=2576$$

Hence, the required percentage $$=\dfrac{(1656+1472-2576)\times 100}{2576} =21.4\%$$
