Yesterday’s Riddle: Tennis Ball Balance
7 tennis balls are identical in every way, except that one of them weighs slightly less than the other 6. How can you identify the lightweight ball with no more than two separate weighings using a balance scale?
Solution: Place 3 balls on each side of the balance scale. If the 2 sides balance out, you have found the lightest ball (the one set aside). If the two sides do not balance out, the lightest ball is clearly one of the 3 balls on the less weighted side. Now for your second weighing, place 1 each of your remaining 3 balls on either side of the scale. If the two side balance out, the lightest ball is the one set aside. If not, the lightest ball is obviously the one on the less weighted side.
