Diagrams are always potential hazards for errors when setting puzzles.
This week I m going to give you three puzzles to solve, and invite you to identify what the intended answer was and where any errors occur, either in the diagram or the text. Puzzle 1 Place the weights on the pans so that the system balances. Puzzle 2 Divide the square into four parts, so that each part contains the same total. We ll go through the issues raised next week, but feel free to email me if you want to send me your answers before then. All correct entries received will get a name check in the next column.
