There can be no carry from the
hundreds column. So, A
must be 7 to have a twodigit
product of 3 that ends in
1. Thus, E is 2. Then C must
be 4 with no carry from the
units column. Since there is
no carry in the units column,
D must be 3 since 1 and 2 are
used and any larger D would
produce a carry. Thus, F must
be 9.

Math Prob.  Trading In The Philippines (S587)
From the book
"More Mathematical Puzzles of Sam Loyd" 

Edited by Martin Gardner
From: Dover Publications in 1960 (cf,md4,2)
I recently came upon an old travel
book that described some of
the primitive methods once used
for conducting business in the
Philippines. The traveling
merchant shown in the picture uses
a balance scale and four metal
rings that serve as weights.
The rings are different weights
and sizes and he carries them
on his arms like bracelets.
With these four rings, the trader
can weigh anything from a
quarter of a pound up to ten
pounds. These weights enable the
trader to get within a quarter
of a pound of any weight within
the limits mentioned.
What are the weights of the four
rings?

The problem is to find three
different digits such that, in
whatever order they are used
to make a threedigit number,
that number will not be divisible
by: 3,5,7,11,13,or 17.
Furthermore, since more than
one solution is possible, we
are looking for the three digits
whose product is the greatest.
To ensure that there is no ambiguity,
suppose the three digits
are a, b, and c. Then, none
of the numbers: abc, acb, bac, bca,
cab, and cba will divide by
3, 5, 7,11,13, or 17 and also the

two cookies more if she brought
the same number she had that
day. However, the absentee list
was low the next day, and she

red, yellow, and green.
"I showed my girls how to make seven

My only condition was that she should
