In a recent survey of musical preferences among BrainDen'ers, it was determined that

280 like jazz; 254 like classical; 280 like country/western.

97 like both jazz and classical; 138 like both classical and country/western; 152 like both country/western and jazz.

Only 73 like jazz and classical and country/western.

How many BrainDen'ers were interviewed?

500. Each circle contains the number of people who like a certain music. I found it easier to start from those who like all three, then those who like only 2 types of music and finally those who only like one (The math is shown above each number). Don't know if this is clear enough... If not, ask.


PS. J:Jazz - C:Classical - C/W:Country/Western
