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 institute Q and R together
= [(15% + 10%) of 8550]
= 25% of 8550.

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

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

= 80%.
