Hen and Egg Problem

If a hen and a half lay an egg and a half in a day and a half, how many eggs will half a dozen hens lay in half a dozen days?

Answer

Two dozen or 24 eggs.

If you increase both the number of hens and the amount of time available four-fold (1.5 x 4 = 6), the number of eggs increases by 16 (4 x 4) times, giving 24 (1.5 x 16) eggs.
