Solution to Puzzle #180: White and Black Beans

This was one of the simpler puzzles and I got correct answers from many. This included Mahi Saraf, Anahat (Prakhar’s son), Vishal Poddar, Pratik Poddar and Praneeth. Well done all.

The answer is “white”. I am borrowing the answer from Mahi.

The bean remaining will always be white because every time we are doing something to the pot we are taking out only 0 or even number of white beans. As we started with an odd number of white beans, the bean that will be left will be white.

Hope you all enjoyed the puzzle!
