HOT KEY PUZZLE FOR JUNE 2003
This is the diagram you need and can download for the June 2003 Hot Key puzzle. The puzzle is as follows:
Each of the 5 columns, 5 rows and the two main diagonals add up to the same total. Can you fill in the missing numbers?
The diagonal 5555x and the vertical 4556x both sum to 20+x and x is present twice in the top row (5x93x) so 17+2x = 20+x which makes x=3. So all the rows and columns add up to 23. The rest is easy.
