A recent survey of college students on a big campus was conducted to find students'
preferred method of getting to class. The results showed that 35% of students walk to class,
20% take the bus, 25% ride a bike, and 15% drive; the remaining students rollerblade to class.
If each student preferred only 1 method of getting to class and 75 students preferred
rollerblading, how many students were surveyed?
~~~~~~~~~~~~~~~

35% + 20% + 25% + 15% = 95%.


So, 75 students, who prefer rollerblading, comprise 5%.


Therefore,  75%2F0.05 = 7500%2F5 = 1500 sudents were surveyed.    ANSWER

Solved.
