The given charts show the distribution of IT employees who were enrolled for Certification exam and the employees (out of those enrolled) who passed the Certification exam from different centres. Study the charts and answer the questions that follow.
Find the difference between the number of employees enrolled from centres E and C together and the number of employees who passed from centres D and A together.
Number of employees who enrolled from E and C were, 8+10= 18% of 23550
Which is equal to 4,239
Number of employees who passed from D and A were, 16 + 18 = 34% of 3700
Which is equal to 1,258
The difference would be 4239-1258 = 2981
Therefore, Option A would be the correct answer.
