It's asking how much the price has reduced, not what the percentage of the new price is.
1800/3000 = 60%
Write and solve an equation of ratios:
900 students 45 teachers
------------------ = -----------------
x 110 teachers
Cross multiplying, we get (900)(110) / 45, or
so x = # of students in the high school = 2200 (answer)
The value of the given expression will be 3√5.
