Intriguing Conundrums, Confusing Paradoxes, Baffling Conjectures and Challenging Puzzles

This collection of over 50 puzzles and logical problems - in over 200 pages - is great fun and includes some classic and some new problems. There are short puzzles that require no mathematical knowledge and some that require rigour and mathematical logic.

It is also unique in offering 2 levels of answer and explanation

  • for those who want the answer and an explanation for the given problem, and
  • for those who want that explanation in depth and for the type of problem. So there's some serious mathematics there too, and techniques galore to solve problems in the future. 

Accessible, well illustrated and in colour, the book has a unique, friendly readable style. Any puzzle lover will enjoy it and be challenged.

The title comes from the author's simple challenge:

If a Hen and a half, lay an Egg and a half in a Day and a half, how many eggs would 3 hens lay in a week?

Get working...! 

Go on Try Them! 

See examples, and plenty of fun sample problems on the HalfaHen website.
