...rival gangs.? It’s a remote town of cowboys, with a fierce battle going on between rival gangs. A man has to cross the town along with a sheep, a bag of grains and a wolf. Anybody crossing the town will be caught in fierce gunfire.
The only other means of crossing the town is an underground tunnel. It’s pitch dark inside the tunnel and it’s impossible to see or to cross the tunnel without light. The only source of light: Candles, sold in the town, Limited supply so candles very expensive. Each candle is 10 inches long. To prevent burning of hands by molten wax the candles have to be put out before the last inch. This way each candle can give light up to 45 minutes. Means of transport inside the tunnel, A 4-wheeled-trolley – but all wheels in dissembled condition.
Before getting the trolley rolling all the wheels have to be assembled on it. It takes 15 minutes to fit each wheel. The trolley takes one hour to travel from one end to other.
But there’s another problem. There is just enough space in the trolley to accommodate either the sheep, or the bag of grains or the wolf along with the man. If left unattended, the sheep will eat the grains and the wolf will kill the sheep.
The man has to reach the other end of the tunnel safely with the sheep, the bag of grains and the wolf. How will he do that with minimum expense i.e. using least number of candles?
