Just a random math problem for the day :-)

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?"

17 !!

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

31

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 (^_^)

 

Thanks everyone!

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.

 

Goodnight guys!
