The silence of the sheep
Cam has requested this on from the old ToM site. I’ve corrected the worst of the grammatical errors and rephrased it so that dad can have more than 10 sheep; but have left everything else alone.
A guy is owner of a certain number of sheeps for god’s sakes and also the father of three sons who for some reason are expert logicians. So here comes the question. Clever as you are will think to yourself, now all this guy needs is to believe he’s about to die so that he can make a will to divide the sheep among the sons, right? Right!, except he calls them together (the sons, not the sheep) and tells them how many sheep (not sons) he owns and adds that:
1. The eldest will inherit the most sheep
2. The youngest the least
3. No son gets more than 10 sheep, which as we all know would be a crime.
4. He then whispers in each son’s ear how many sheep he personally will inherit.
After that he proceeds from the eldest to the youngest, asking each aloud if he can calculate how many sheep each of his brothers will inherit and each replies, “no”. He does it again and again each replies, “no”, but then the eldest son on being asked the question once more says, “yes, each of the last two ‘noes’ (that’s the plural of ‘no’) gave me some information, and I now know (no plural of ‘knows’) how many sheep each of us will inherit.” What’s the bet you’re already wondering how may sheep each son will get?
So, how many sheep does each brother get?
