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?

68

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%
