Answer is 2.
Solution:
Divide the stones into 3,3,2. Put 3 stones on left pan and
3 stones on right pan. If heavier stone is present in any
one of the side then that side will get down. Take the 3
stones from that side and again put 1 stone on left and 1
on right. We can find the heavier stone from this. If both
are equal then the remaining one is heaviest.
While dividing the stones as 3,3,2 when both sides are
equal then take the remaining 2 stones and put it on left
and right.
