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.
Which of the following centres has the highest percentage of the employees passed to the employees enrolled?
Solution
Since the values are given as percentages of the same numbers and we only have to find the highest and not the exact values, we can find the ratio between all of the options and see which is the highest value.
C: 13% of passed/ 10% of enrolled
F: 15% of passed/ 12% of enrolled
B: 17% of passed/ 16% of enrolled
E: 9% of passed/ 8% of enrolled
we can take passed/enrolled as constant K since they are same in all of the calculations, this would give us
C: 1.3 K
F: 1.25 K
B: 1.0625 K
E: 1.125 K
As we can see, C has the highest percentage of employees passed to enrolled ratio.
