TV channel once conducted a 10-episode adventure-based reality show. In one of the episodes, a company “Mayasur Landscape Design” had created a mosaic of tiles on a ground. The ground had various sections of various shapes.
One of the sections (as shown below) is divided into congruent squares. A square, if not along the border, has 8 tiles surrounding it. As designed by “Mayasur”, each tile can have hard ground below it, a coffee plantation on it or swampy mud below it. A participant has to enter this section from the designated side and reach the stage on the other side. A tile having solid ground below it is “safe” to pass on while a tile having mud below it is “fatal”. Squares that do not have a coffee plant on them are marked with a yellow or blue tile. Blue tiles correspond to solid ground. The number in any green square denotes the exact number of tiles around it that have mud below them.
A contestant can only walk facing the stage or parallel to the stage. One contestant has got alleged insider information that 18 tiles definitely do not have mud below them. Is this information correct? What must be the value of x? If a contestant has crossed this section successfully, what path has he chosen?
