| Ok, this is an old chestnut, but is the single one of these sorts of problems that took me the longest time (and led to at least 1 man-day's loss of productivity at Deloitte). I think of 2 integers between 1 and 100. I tell Peter the Product and Simon the Sum. 1.) Peter: "I don't know what the numbers are" 2.) Simon: "I knew you wouldn't" 3.) Peter: "Now you've siad that, I do know" 4.) Simon: "Now you've said that I also know" What are the numbers? No computer programmes allowed | ||

mjb said: OK, so I rushed the previous one a bit. East is definitely undefined along the whole of the straight line that runs through the North and the South pole. Also, how can you possibly walk at the centre of the Earth?How aboot the centre of the earth, or is East undefined there as well. In which case, go out far enough such that your 1 mile East will take you back to where you started the Eastward leg. You are walking on the Earth's surface. And before you ask, no other form of transport is used. | ||

Rich said: At a position one mile north of the place where walking east around the south pole brings you in a full circle 1 mile in circumference, back to the same point. Is the right answer.If we assume the small area around the South pole is flat, our start point would be any point on the circle which is 1 + 1 / (2 * pi) miles North of the South pole. Where else could I be? | ||
