Why A Hen and a Half?
“If a Hen and a half, lay an Egg and a half in a Day and a half,
how many eggs would 3 hens lay in a week?”
This should be a relatively easy puzzle to solve quite quickly in one’s head, but, maybe surprisingly, when put on the spot, few people get the answer right, first time.
Before you carry on, give yourself 30 seconds or so (but not longer) to work this out in your head – don’t write anything down or use your calculator, just find the first, best answer you come up with, before reading any further.
