Q.
You have 9 bottles of same size, 8 out of 9 bottles have same weight
but one bottle weights little less. How will you find out which bottle
weights less if you have an indian weight machine on which you can
weight bottles for 2 times only?
This question aims at finding out your logical and reasoning power so that you can calculate real life job problems.
My answer after few minutes of rough work on a page that they provided.
I answered:
Put 3 bottles on left and 3 bottles in right hand side of weight machine. If both are equal than
Again
put 1 one left side and 1 on right side, if weight is same then the the
remaining bottle has lesser weight than all other 8 bottle.
Interviewer: great!! You must be having prior idea of this!
Me: yes I just calculated this during rough work and that's what a manager is expected to do. Fast decision and calculated risk.
Interviewer: you are in!!
