Study the following graph and answer the question that follows.
Number of students that appeared and qualified, from various colleges, at a scholarship examination.
The average number of students that qualified in the examination from Colleges X and Y is what percentage of the average number of students that appeared for the examination from the same colleges?
Answer & explanation
Correct answer: option 2
Number of students qualified from colleges X and Y = \(\frac{1800+1600 }{2}\)
= \(\frac{3400 }{2}\)
= 1700
Average number of appeared students from college X and Y = \(\frac{3000+2000 }{2}\)
= \(\frac{ 5000 }{5}\)
= 2500
Required percentage = \(\frac{1700 }{2500}\) × 100
= 68%
