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:

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

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%

Correct answer is B

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)/(25% of 8550) x 100 ) %

= ( (30 x 5700)/(25 x 8550) x 100 ) % = 80%
