In the year 2007 (not shown), n male students and 300 female students enrolled in College Y, and the median total enrollment for the 8 years from 2000 through 2007 became 834.5. What is the value of n?

535
540
541
551
Total number of students in 2007 = \(300 + n\)
Arrange the Total number of students in ascending order first760 800 813 (300 + n) 828 850 891 933
NOTE: (300 + n) has to be the 4th or 5th term - otherwise the median would not be 834.5Median = 834.5 = Average of 4th and 5th term
So, Sum of 4th and 5th term = 1669
Therefore, 300 + n + 828 = 1669
n = 541
Hence, option D
