weigh two groups of 3 plates each on either plate of the
balance...if the plates are in d same level it means the
plate of different weight is in the third group......so take
the third group of plates.....select any 2 and weigh

can identify d plate of different weight in a group.....then
repeat the same procedure...take any 2 weigh and find out
