## New Language Puzzle

Apologies - this is not a digital resource, but it is such a wonderful puzzle that I just had to include it.

I lived in Eugene Oregon in the summer of 1980. A local newspaper had a wonderful weekly puzzle column, so each week I would buy the newspaper and go to a coffee shop and attempt to solve that week's puzzle. The link below is my favourite puzzle from that era.

I have no idea who the author is, so if you have any knowledge about this puzzle can you please click on [Contact Us] and share what you know. The file is available as a Word doc or as an Acrobat pdf file.

Three thumbs up!

Note: This is not a trick question. This is a real math problem so don't say that a bus has no legs. Also, there is no driver on the bus, so don't add any legs for a driver.

There are 7 girls in a bus
Each girl has 7 backpacks
In each backpack, there are 7 big cats For every big cat there are 7 little cats

Question: How many legs are there in the bus?

## Changing the Border & Dividing a Quadrilateral

Changing the Border
This is a nifty puzzle whose solution is based on the area of a triangle. The land is divided into two parts (P and Q) by the border ABC. Redraw a straight border line passing through point A so that each of the areas does not change.
