- 28 Dec '08 15:44 / 2 editsI'd like to create a thread specifically devoted to logic and numerical (not 'maths' puzzles as such, but ones requiring numerical reasoning) - the sorts of puzzles one might find in a book of brainteasers.

Please post any interesting logic or numerical puzzles you know of/can find. Thanks

I'll start the ball rolling:

How many leap years will there be between 2001 and 3001? Remember that at the turn of a new century, years are only leap years if they are multiples of 400. - 28 Dec '08 20:27
