Puzzle 598
Using the BrainBashers Ecommerce solution, James ordered a fishing rod, priced at $3.56.
Unfortunately, James is an fisherman who lives in a very remote part of Greenland 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!
[Ref: ZFEL]
Hint: The fishing rod does end up in a real box.
Answer:
One solution is to use a box which measures 4 feet on all sides, the fishing rod will fit within the diagonal of the box with room to spare.

Puzzle 600
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.
10M = 50
M = 5
So we have 5 mice (and 10 cockroaches). We can use M = 5 in (1) to give:
B + 3 x 5 = 50
B + 15 = 50
B = 35
So, C = 10, M = 5 and B = 35. Checking that 10 + 5 + 35 = 50, and 10 x 6 + 5 x 4 + 35 x 2 = 150. QED.
