Question

There are 250 students taking band, chorus, or both. If there are 180 students taking band and 60 students in both band and chorus, how many students are only in chorus?
a.10
b.60
c.70
d.120

Answer 1

If we are looking for students that are in chorus alone you get the answer a. 10

Answer 2

The answer is A. 10. You get this answer by adding the sums of the students taking band and the students taking band and chorus. 180+60=240.

Next, you take the original number and subtract it by the number you just came up with. 250-240=10

That's how you get 10.
