SIMPLE MULTIPLICATION.





(Money Puzzles)
If we number six cards 1, 2, 4, 5, 7, and 8, and arrange them on the
table in this order:--
1 4 2 8 5 7
We can demonstrate that in order to multiply by 3 all that is necessary
is to remove the 1 to the other end of the row, and the thing is done.
The answer is 428571. Can you find a number that, when multiplied by 3
and divided by 2, the answer will be the same as if we removed the first
card (which in this case is to be a 3) From the beginning of the row to
the end?
