Answer / bharathi sundaravadivel
1]Suppose there are 5 jars and one physical balance,take any 4 out of them and place 2 jars on each side of the scale remains horizontal,then the remaining jar has the contaminated pills.
2] Else if the balance shifts to one side then the contaminated jar must be on the side which is lifted upwards.so remove one of the jars from either side. if the balance is still tilted to one side then the jar which is left on the side which is tilted is the contaminated jar.
3] If the balance becomes horizontal when you removed it, the jar you removed from the previously tilted jar is the required contaminated jar.
