20 Bags of Chocolates Puzzle
Suppose you have 20 bags,
What is the minimum number of eggs needed
So that you have a different number of eggs in each bag?
(Hint: Think out of the box and go against your common sense :P)
Put 1 egg in each bag except 1.
Put the empty bag in a bag with 1 egg.
Put that bag in another bag having 1 egg and so on.
This way, you use only 19 eggs,
Now the top bag has 0 eggs,
the next bag has one, the next bag has 2 and so on.
(It said to go against common sense :P )
