For purposes of making on-campus housing assignments, a college classifies its students as Priority A (seniors), Priority B (juniors), and Priority C (freshmen and sophomores). Of
the students who choose to live on campus, 15% are seniors, 30% are juniors, and the rest
are underclassmen (freshmen and sophomores). The most desirable dorm is the newly
constructed Gold dorm, and 70% of the seniors elect to live there. 10% of the juniors also
live there, along with only 5% of the freshmen and sophomores. What is the probability
that a randomly selected student resides in the Gold Dorm?

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4
