Question

There are 7 marbles in a circle. How could you get all 7 marbles ito a box by moving them in groups of only 2 or 3 at a time? You must follow this rule: Groups of 2 may ONLY move right,and groups of three may ONLY move left. How could you move all 7 marbles from a circle to a box?

Answer can not be too complicated!

Answer 1

Is the box to the right or left of the circle?

Answer 2

The right.

Answer 3

Move the first six in three moves (2 each time). That leaves 6 in the box and 1 in the circle.

Now move 3 from the box to the circle. Can you see what you'll do from there?
