If 20 students take music and 26 take art, then you have a total of 46 students. If 2 of those students take both, that means they are being counted twice in that figure of 46 students, so there are actually 44 different students. 60 – 44 = 16

60-48=12 these are the students not enrolled in either music or art.

20 take music, 26 take art and 2 take both. Add up these numbers together:

20 + 26 + 2 = 48

Now, to get the number not involved in any, simply take 48 from 60.

60 – 48 = 12

12 are not enrolled.

It looks like this:

60-(20+26+2)=

It could be a trick question

just subtract the other numbers from 60.
