There is a circular table. It has 60 chairs. Drakula came and sit on a chair beside another person. What is the minimum no. of person will be so, that wherever he sits he always gets to sit beside a person

Options: 30, 20, 15, 10(not sure)

• Ans : 20
  Exp: Think from basics..
  if total seats N = 5 in a circular arrangement ( _ _ M _ _ M ) where first ( _ ) is connected with last Man(M), then min no of persons required= 2.
  similarly If N = 9, Man required = 3 i.e,( _ _ M _ _ M _ _ M )
  
  If N= 12, Man required = 4 i.e, ( _ _ M _ _ M _ _ M _ _ M)
  have u got any relation??
  the no of man required is = Total no of seats in circle / 3
  So, A/Q total seat = 60. Man required = 60/3=20 Ans.

• 20 will be the ans
  the max gap diff between 2 person allowed is 2.
  so if you stretch the round table into a line the figure will look like _ _ man _ _ man _ _ man _ _ man...
  so its clear that in each 3 seats there will be one man so ans will be 60/3=20
