Of the 60 students in the drama club, 36 take mathematics, 27 take physics and 20 students take both mathematics and physics. How many drama club students take neither mathematics nor physics?

We  have that 

 

(36-20) take only Mathematics = 16

(27-20)  take only Physics  = 7

20 take both....

 

So  (60) - ( 16 + 7 + 20) =   

 

60 -  43   =

 

17  take neither....

36+27 = 63

 

63-20 = 43

 

60-43 = 17.

 

17 people took neither.
