## THE PIERROT'S PUZZLE.

(

Money Puzzles)

The Pierrot in the illustration is standing in a posture that represents

the sign of multiplication. He is indicating the peculiar fact that 15

multiplied by 93 produces exactly the same figures (1,395), differently

arranged. The puzzle is to take any four digits you like (all different)

and similarly arrange them so that the number formed on one side of the

Pierrot when multiplied by the number on the other side shall produce

the same figures. There are very few ways of doing it, and I shall give

all the cases possible. Can you find them all? You are allowed to put

two figures on each side of the Pierrot as in the example shown, or to

place a single figure on one side and three figures on the other. If we

only used three digits instead of four, the only possible ways are

these: 3 multiplied by 51 equals 153, and 6 multiplied by 21 equals 126.
