93.The Number Blocks.
Arrange the blocks so as to form the two multiplication sums
915 x 64 and 732 x 80, and the product in both cases will be the
same: 58,560.
94.
Foxes and Geese.
The smallest possible number of moves is twenty-twothat is,
eleven for the foxes and eleven for the geese. Here is one way of
solving the puzzle :
105 116 127 512 61 76
18 29 34 83 910 4^9
127 18 61 72 83
3_4 105 910 411 512
Of course, the reader will play the first move in the top line, then
the first move in the second line, then the second move in the top
line, and so on alternately.

the table. The
