This is a “addictive” problem – hard to get rid of until you solve it. Thanks to Pooja Goyal, my wife, who gave me this puzzle a few days back from a Math festival she was at.
Place 5 wolves and 3 sheep in the grid in such a way that no wolf can get to (and eat) any of the sheep. A wolf can move in a straight line any number of squares up or down, left or right, or diagonally.
Note: You must have exactly 5 Wolves and 3 Sheep on the grid.
As always, please send your answers as comments within the blog (preferred), or send an e-mail to firstname.lastname@example.org. Please do share the puzzle with others if you like, and please also send puzzles that you have come across that you think I can share in this blog.
