Flaptekst

“I’m bored. Give me something to do,” said Joe. “And what’s the time anyway?”
Ben glanced at his watch and did some quick figuring. “When I checked my watch this morning,” he replied, “the hour hand was exactly where the minute hand is now, and the minute hand was one division before where the hour hand is now.”
“You mean minute division?” Joe asked.
“That’s right,” Ben told him. “And both hands are exactly at minute divisions now.”
What was the time?”

If you are bored with the simple problems you usually find in books on recreational mathematics, you will be very pleased with the 100 challenging mathematical teasers in this book. They are among the best of the relatively difficult algebraic problems from J. A. H. Hunter’s widely read newspaper column, “Fun with Figures.” And none have appeared in any other book.

In addition to “Both Hands,” these delightful story teasers include “Who Spilled the Coffee?,” “A Random Mailing,” “Who Glubs Glygons?,” “The Jewel Box,” “A Matter of Squares,” “Uranium Triangles,” “Men on the Moon,” “Two Magic Squares,” “Too Many Girls,” “At the Casino,” and “A Nest Egg.” Confirmed puzzle fanatics will need no urging to try these puzzles, but less experienced puzzlers will want to take a look as well.
Once they get the hang of these problems, they will probably be hooked. Step-by-step solutions are provided for all 100 puzzles, and two appendices give instruction in algebraic techniques that are useful in solving the puzzles.
