Puzzle 211
Can you find five countries hidden in the following paragraph:
Dominic had a certain way with animals, he could almost talk to them. By tickling it under the chin, a rabbit would roll over and let its belly be tickled. This technique was sometimes used to good effect in gaining trust, and allowed a vital yearly treatment to be performed safely. The removal of nits. Using a vet approved shampoo to clean the fur (and not a blend of malt and water!).

Puzzle 212
Start with a number larger than 0, square it, add 4, double, take away 3, times 4 and finally subtract the original number.
If you were now left with 20, what number did you start with?
Reasoning
If we convert the question to algebra, we have:
((n^2 + 4) x 2 − 3) x 4 − n = 20
Expanding the brackets and simplifying gives:
(2n^2 + 8 − 3) x 4 − n = 20
(2n^2 + 5) x 4 − n = 20
8n^2 + 20 − n = 20
8n^2 − n = 0 (*)
8n − 1 = 0
8n = 1
n = 1/8
In the equation marked (*) zero is also a potential solution, but as the question tells us that we "Start with a number larger than 0" we know that n can't be 0, and therefore we can safely divide by n.
