NO!! It will surely take a minimum of four or more tries!!
not 2 or 3....
(According to question)
Let us take 2 balls for instance of which one is different
weight.. different in the sense it may be heavier or
lighter, as it was also specified in the question..
now if we put both of them in weighing balance, any of the
side may go to either up or down.. we never know which is
the wrong one. so we need to compare with the left out once
also..
i can solve it but need to type a lot... sorry.. but in a
simple way i can say it takes atleast 4 not 2 or 3..
