There can be no carry from the hundreds column. So, A
must be 7 to have a two-digit 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.

 Subj:    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?

Subj:     MATH PROB. - Find Three Digits (S541c)
From: Puzzles And Brain Teasers on 4/30/07
Source: (Removed from apuzzlezone.com)

The problem is to find three different digits such that, in
whatever order they are used to make a three-digit 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
product of a x b x c must be as large as possible.

Miss Tryon is the teacher of a large class of girls at one
of our more enterprising schools.  She is responsible for
several subjects, including what is vaguely called "handwork,"

interesting experiment this week," she told me. "I had
available a large number of beads.  They were of three colors:
red, yellow, and green.  "I showed my girls how to make seven-
intervals-and then I suggested that each girl should make a
bracelet for herself.  My only condition was that she should
use three beads of any one color; two of a second color; two
of a third."

"And what was the experiment exactly?" I asked.

"Why," said Miss Tryon, "I wanted to see how many different
bracelets were produced by these haphazard instructions.
There were thirty-two, which is about what might have been
expected.  It would have been possible-but only just possible-
for every girl to construct a bracelet different in appearance
from all the others."
