Solution to Puzzle #6: Identifying the Faulty Ball

I was very happy to see many new “puzzle solvers” for this puzzle. I was particularly impressed with Aadi Kuchlous and Sahil Kuchlous who solved the 6 and the 9 balls puzzle respectively. Same is true for Arushi and Anisha Goyal. Many adults gave the correct answer for the 12 balls puzzle.

Answer to the first two parts is simple and is in the video link.
