there are 8 bags of rice looking alike,7 of which have equal weight and one is slightly heavier,the weighing balance is of unlimted capacity.using this balance,the mininmum number of weighings required to identify the heavier bag is

• 2
  number of bags=8
  3^X=8==>X=2(even if it is 1.99 it should be taken as 2)
  
  (if bags are 80==>3^X=80=>x=4
  (from 28 to 81 same answer i.e....3.001 to 3.99999 is 4)
  the technique is we should equal bags=3^x and x is answer)
