A convention is held where all the big logicians are summoned. The master places a band on everyone's forehead. Now all of them can see others bands but can't see his own. Then they are told that there are different colours of bands. All the logicians sit in circle and they are further explained that a bell will ring at regular intervals.

The master assures the logicians that the puzzle will not be impossible for anyone of them. How will the logicians manage ?
