Finding the Heavier Ring Without Weights on a Balance Scale

To find the heavier ring without using weights on a balance scale, you can follow these steps:

1. Step 1: Divide the Rings into Two Groups - Start by dividing the six rings into two groups of three.

2. Step 2: Weighing the First Group - Place three rings on each side of the balance scale and compare their weights. - If one side is heavier, you have identified the group containing the heavier ring.

3. Step 3: Weighing the Heavier Group - Take the group with the heavier ring and place one ring on each side of the balance scale. - The heavier ring will cause one side of the scale to tip down, indicating which ring is heavier.

By following these steps, you can identify the heavier ring using only two weighings on a balance scale without the use of weights or additional measuring tools.
