Is there a solution for two acts of balancing balls on Puzzle 8?
If you have 8 bullets have exactly the same appearance, but one of them is slightly heavier, on a scale of balance, as you know which ball is heavier? There Two-step solution addressing all the scenarios? In three simple steps, but two, is it possible?
Yes. Firstcome no two groups of 3 balls (three balls on each side of the scale). If the scale weight, the ball is even harder of the two weighed. Now, put one of them on each side of the scale and more difficult one is on the side of the scale is smaller. If not balanced, the heavier ball is one of three on the bottom. Now two of those three and one of them, each side of the scale. – If the scale weight, heavier ball is that you only consider – If it is not difficult to balance the ball is that on the bottom side. Now try this: one of the balls is either heavier or lighter, but do not know what it is. Can still found at 2 weight? In 3?
