let A be the set of students in the band, B be the set of students in sports team.
then A=80, B=160. A intersection B= 60. no. of the students that are neither in band nor in sports team is given by the complement of a union B. now, a union B = A + B -A intersection B = 80 + 160 - 60 = 180. so the answer is 200 - 180 =20.
