4. Three men had dinner together and decided to share the cost. The waiter produced a bill for £30, so each contributed £10. When presenting the money to the cashier, the waiter discovered that the correct total should have been £25. The cashier returned £5 to the waiter, who pocketed £2 and returned £1 to each of the diners. Thus each had paid £9 and the total payment was £27. But the waiter had only £2; what happened to the other £1? Answer
5. Newt, in a mood of somber, if not sober, cogitation, sat pondering the two glasses in front of him. One contained whisky and the other contained an equal quantity of brandy. With as steady a hand as he could manage, Newt transferred a spoonful of brandy to the whisky glass. After stirring it with slow deliberation for several minutes, he then transferred a spoonful of the mixture back to the brandy glass. Aided by several glasses of gin, he then attempted to calculate whether the whisky glass contained more brandy than the brandy glass contained whisky. Could you tell him? Answer
6. This morning, I discovered that a bookworm had eaten its way through the 12-volume encyclopaedia on my bookshelves. It had done so in a perfectly straight horizontal line from the first page of volume 1 to the last page of volume 12. Each book is 50 mm thick, with the pages taking up 40 mm of that. What total distance had the bookworm travelled? Answer
7. The will of farmer Giles stipulated that his three sons were to receive 1/2, 1/4 and 1/6 of his estate. Since the estate consisted of 11 cows, the lads were understandably at a loss as to how to share out the bequest until the neighbouring farmer Brown dropped in to pay his condolences. "Simple!" said he. Putting one of his own cows with them to make a herd of 12, he gave six cows (1/2 of the herd) to the first son, three cows (1/4 of the herd) to the second son and two cows (1/6 of the herd) to the third son. Only his own cow remained which he took back with him. Was that fair shares? Answer
