As I was going to St. Ives, I met a man with seven wives; Each wife had seven sacks; in each sack, there were seven cats; each cat had seven kits. Kits, cats, sacks and wives, how many were going to St. Ives?
Unless you are a wife yourself in which case the answer is 1
This of course is assuming these people were travelling in the opposite direction and you didn't just overtake them in which case the answer would be 2401 (unless you were a wife in which case the answer is 2402)
