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?
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%
