of 50 students, 40 are in the football team and 30are in the cricket team. how many are in both if six do not play either.

Let F be football only
FC football and cricket
C is cricket only
F+FC+C=44
and
F+FC=40
C+FC=30
put the second equation into the first
40+C=44 or Cricke only is 4
then FC is 26
and F is 14
