Puzzle #30: Red, White and Blue Weights

Back to weights – Found this very nice puzzle in Mathematical Circus, by Martin Gardner (Chapter 11, Problem #6). This one was originally created by Paul Curry, who was also an amateur magician.

You have six weights. One pair is red, one pair white and one pair blue. In each pair one weight is a little bit heavier than the other but otherwise appears to be exactly like its mate. The three heavier weights (one of each color) all weigh the same. This is also true of the three lighter weights.

In two separate weighings on a balance scale, how can you identify which is the heavier weight of each pair?

As always, please send the answers to alokgoyal_2001@yahoo.com and if you like the puzzle, please feel free to share with others, specially children.

Happy weighing!
