The BrainBashers mechanical computer is a very sensitive device, it consists of interlocked toothed gear cogs.

The largest cog has 242 teeth and the others have 160, 64 and 22 respectively.

By accident, Daniel started to rotate the largest cog.

How many revolutions must he rotate the largest cog make before the computer is back in its starting position with all of the cogs where they started?

Using the BrainBashers E-commerce solution, James ordered a fishing rod, priced at $3.56.

Unfortunately, James is an fisherman who lives in a very remote part of Puzzleland and the import rules there forbid any package longer than 4 feet to be imported.

The fishing rod was 4 feet and 1 inch, just a little too long, so how can the fishing rod be mailed to James without breaking the rules? Ideally James would like the fishing rod to arrive in one piece!

During the recent BrainBashers cipher convention, a Morse code contest took place. The contest consisted of a Morse code transmission where the spaces between the letters and words were missing. Can you find the ten boy's names?

Luckily, BrainBashers has provided you with a listing of the Morse code characters:

In farmer Brown's hay loft there are a number of animals, in particular crows, mice and cockroaches.

Being bored one day, I decided to count the animals and found there were exactly 150 feet and 50 heads in total, and there were twice as many cockroaches as mice.

How many of each animal were there?
