Then you come to the room and hand over 1 nut to Arnab, 2 to Bilal and 3 to Chan. Then tell them to take more nuts in your absence- (1) The one who has the bag should take as many nuts as he was given the first time

(2) The one with the phone twice as many as he was given

(3) And the one with the chair four times the number.

The rest will remain in the plate.

To solve the above problem, let us understand that 3 objects can be distributed in 3! i.e 6 different ways. Find out how many nuts are taken for each combination and how many are left. The remainder is different for each combination and hence result can be predicted from the remainder.
