Question 13
Andy has to pass through an underground maze. The enchantment on the maze requires Andy to pick up the piece of stone in the first room when he enters the maze. Then in each subsequent room he must exchange it with the next stone if that one is heavier.
The number in each room represents the weight of the stone in it, in kg. Andy can only walk to the right or down on the map. He also wants to carry as little weight as possible when he leaves the maze.
What is the least weight, in kg, he can leave with if he only walks right or down?
