In a group of 30 persons,a total of 16 take tea while 9 take tea but not
coffee. how many persons in this group take coffee but not tea?

• 14 persons take coffee but not tea.
  
  As per the qn., out of 30 persons totally 16 take tea.
  So, 30-16 = 14 (Remaining are take coffee)
• 12 years agoHelpfull: Yes(5) No(7)
• No. of persons who take only tea=9
  Total No. of persons who take tea =16
  So , nO. Of persons taking both coffee & tea=16-9=7..(assuming that every person has to take atleast 1 of the two)
  ...So T=people taking only tea
  TC=people taking both
  C=people taking only coffee ; N=Total people
  Clearly , T+TC+C=N
  ...so C=N-T-TC=30-9-7=14
  hENCE aNSWER is 14.....

• ans = 14
  total persons = 30
  7 take tea and 9 take tea and coffee
  means remaining 14 take coffee
  otherwise the answer is zero since nothing was described about the remaining 14 persons

  person whose take coffee not tea is , Z = X-Y
  = 30 - 16
  = 14
