Can somebody help me solve the following question?

All of the students of Music High School are in the band, the orchestra, or both. 80 percent of the students are in only one group. There are 119 students in the band. If 50 percent of the students are in the band only, how many students are in the orchestra only?

Thanks

I interpreted the question in another way... :-(." 80 percent of the students are in only one group" I interepreted it as that 80% belong to either only band or either only orchestra. This was I calculated people in both as 30% and only orchestra as 20%.
