It’s an old riddle that only works with imperial units. In traditional British fashion, the imperial weights and measures had two pounds in it, and you had to choose the right pound for the right thing you were weighing. The troy pound was used to measure metals and only has 12 ounces, whereas the pound used to measure feathers had 16, so a pound of feathers was 4 ounces heavier than a pound of lead or gold or whatever.
