<font face="Times New Roman" size="+2">


50 must be 1/3 of those who take chorus or have nothing.  So those that take chorus must number 100.  Then 150 must be 5/6 of those that have band, chorus, or nothing, so there must be *[tex \Large x\ =\ \frac{6}{5}\ \times 150\ =\ 180] who have have band, chorus, or nothing.  Then 180 is 3/4 of everyone. *[tex \Large x\ =\ \frac{4}{3}\ \times 180\ =\ 240]
