A guidance counselor is planning schedules for 30 students. Sixteen students say they want to take French, 16 want to take Spanish, and 11 want to take Latin. Five say they want to take both French and Latin, and of these, 3 wanted to take Spanish as well. Five want only Latin, and 8 want only Spanish. How many students want French only?

• French: 16
  Spanish: 16
  Latin:11
  French and Latin (some spanish students included): 5
  Spanish French and Latin: 3
  Latin only: 5
  Spanish only: 8
  
  Let's first solve the problem by looking at the following above. Latin has been mentioned 4 times. That is there are 11 who wants latin, 5 who wants french and latin and 5 who wants latin only. So latin will be good enough to solve the problem. So here:
  5-3=2 (latin and french only, spanish students excluded)
  11-(5+2+3)=1 (spanish and latin students only, french students excluded)
  16-(8+1+3)=4 (spanish and french sudents only, latin students excluded)
  16-(2+3+4)=7 (french only)
  So there were 7 students who chose French only for their schedule.
