Data Interpretation - Pie Charts - Discussion

Study the following graph carefully and answer the questions given below:

Distribution of candidates who were enrolled for MBA entrance exam and the candidates (out of those enrolled) who passed the exam in different institutes:

4. 

What is the percentage of candidates passed to the candidates enrolled for institutes Q and R together?

[A]. 68%
[B]. 80%
[C]. 74%
[D]. 65%

Answer: Option B

Explanation:

Candidates passed from institutes Q and R together = [(13% + 17%) of 5700]
= 30% of 5700.
Candidates enrolled from institutes Q and R together = [(15% + 10%) of 8550]
= 25% of 8550.

Therefore Required Percentage
= ( 30% of 5700 x 100 ) %
25% of 8550
= ( 30 x 5700 x 100 ) %
25 x 8550
= 80%.

The figure should be 30 % of 5700 instead of 30 % of 57000 in the second line of the explanation. Please amend the same.

Any shortcuts for 1710/2137?

In the top chart, 10%+115% = 25%, but 25% of 8550 isn't a whole number, and you can't have half a candidate.

30% of 5700 is 1710.

25% of 8550 is 2137.5.
