6. The Emperor of China was fond of playing chess with his favourite concubine who usually let him win. One day, however, he found himself facing utter defeat and, fearing the humiliation of losing, sent for the wisest sage in the whole of China. "Tell me how to win and anything you ask is yours," promised the Emperor. The wise old sage told him and then, thinking to corner the rice market, asked the Emperor for no more than the amount of rice that would result from placing one grain on the first square of the chessboard, two grains on the second square, four on the third, and so on, doubling the number of grains on each successive square for the whole 64 squares. It goes without saying that the Emperor was as good as his word. How much rice did the old sage receive? Answer
7. Alan and his wife, Anne, along with his parents, Bob and Betty, have been walking all day in the hills and now find themselves near a track they know to be only a 5 minute walk to the bus stop where the last bus of the night will leave in 20 minutes. The problem is that between them and the track is a deep chasm spanned only by a rickety footbridge that is lacking the odd plank and strong enough to take only two people at a time. Because it is dark, the bridge can only be crossed safely using a torch. Obviously, the two people crossing together can only proceed at the speed of the slowest of the pair, and one must return each time to bring back the torch. From past experience, they know that Alan can cross in 1 minute but Bob, being older, takes 4 minutes, and that each man's wife takes twice as long to cross as her husband. How can they ensure that they catch the bus? Answer
