Weighing 9 marbles.

So when comparing two groups of marbles there can be two outcomes 1. Red and blue marbles puzzle you have given 50 red marbles 50 blue marbles and two empty jars. Therefore 2n must be less than 9 which means than n must be 4 or less. Nine marbles you have 9 marbles.

Weigh 9 vs 10 if balanced then 11 is the odd light ball else the lighter of 9 or 10 is the odd light ball. You have a balance scale.

Let s name them for easy understanding. You have access to a balance scale containing 2 trays you may use the balance 2 times. You don t know if that one is heavier or lighter. 1 you have 9 marbles as seen.

2 8 of them are exactly the same. These differ from puzzles that assign weights to items in that only the relative mass of these items is relevant. 1 weighs 1 1 ounce. With 13 marbles this would imply that 9 marbles or more are involved in the first weighing.
