He's actually talking about 24! not 25!. (Maybe because the free square is in a fixed position?) 24! = 6.20e23; and Avogadro = 6.02e23.

I thought the OP was alluding to the slight ambiguity because 1 appears twice in the Fibonacci sequence. You could interpret the approach two ways and do either 21 + 8 + 2 = 31 km or 21 + 8 + 1 = 30 km. Happily these span the correct answer

Apparently placebos are effective, even when you know it's a placebo. See http://www.placebo.com.au/node/31 for a reference to research on this (on the site of a company that sells placebos...)

It's good. I would have found this helpful a few years ago. How about putting the tables into normal form? ie where you currently have the company name as a string in the Person table, instead have an ID which references the Company table.

I guess it's hard to give an answer to an ambiguous input that will please everyone. Personally I would have expected the 1st of the month. It seems unusual that "next June" and "last June" both pick the 4th of the month (today's date); but
