If a crab and a half weigh a pound and a half, but the half crab weights half as much again as the whole crab, what do half the whole crab and the whole of the half crab weigh?
Ответ: 2.1 pounds. The 'whole crab' must weigh 0.6 pounds, and the 'half crab' 0.9 pounds, totaling 1 1/2 pounds. If the former were halved and the latter doubled, the weights would then be 0.3 and 1.8 pounds, totaling 2.1 pounds.
