Puzzle IconUsing 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!

Puzzle IconIn 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?
