how much time does it take to weight a small change in weight bag among 4 equal bags?

• 2 times... 3^x=4 ==>x=2 (x is 1.1 to 2 it is taken as 2)
  
  way 2:make in to 3 parts 1,1,2 ...... put 1 each on each side ....if equal 2 bags which were outside place each on 1 side....
  (for this question if we divide into 2parts gives answer ...but if it is more bags say 7,8, or 80 etc... divide to 3 parts ..... or 3^x=80 ==>x=4)
