A group of 63 college students were comparing notes on their high school activities.
They discovered that:
40 played in a band;
31 sang in a choral group; and
9 neither played in the band nor sang in a choral group.
How many played in the band and sang in a choral group?
I guess 31 sang in a choral group, right?
@Jose: Thank you for trying but that's not the right answer :-( The question is: "How many played in the band AND sang in a choral group?"
I've done a similar task at the school a few years ago.I think the these solution is correct: 63 - 9 = 54 40 +31 = 71 71-54 = 17 17 students played in the band and sang in a choral group.
There are 15 people played in the band and sang in a choral group
63-9=54 54 all who played and sang. 54-40=14; 14 pupils only sang. 31-14=17; 17 pupils played and sang))
@Teddy bear & Ainat Dosalieva: Yes, 17 is the right answer. Congratulations! (^_^)
@Wrom & makdis57: Thank you for trying but try again next time (^_^)
Correction / I wanted to say:
@Wrom & makdis57: "Thank you for trying. Better luck next time."
My head got stuck at the "t" words: thank you, trying, and try. Hahaha.
Oh, well, I should probably sleep now because my brain is not working properly.
