The challenge is to move cards in a manner that each pile has 8 cards by the time you are done.

Question

Let us do a fun activity. Take three piles of cards - one with 11 cards, second with 7 cards and the third with 6 cards and place them on a table.

The challenge is to move cards in a manner that each pile has 8 cards by the time you are done.

The rules are:

1) You can add to any pile but you must add exactly the amount of cards the pile already has. Suppose that a pile has 7 cards, then you will have to move exactly 7 cards from another pile to keep above it.

2) All cards should be taken from the same pile at one time.

3) You have only 3 moves.

Answer 1

Initial position --> 11-7-6
Move 1 --> 7 cards from pile 1 to pile 2- result 4-14-6
Move 2 --> 6 cards from pile 2 to pile 3- result 4-8-12
Move 3 --> 4 cards from pile 3 to pile 2- result 8-8-8
