Trade Convention #2all logic puzzles
Workers with the surnames Butcher, Baker, Carpenter, and Plumber are currently attending an annual convention.
No-one is currently, nor ever has been in the same profession as their name and no-one has had the same profession twice.
Alan is now a butcher, whereas Mr Brian Butcher used to be a baker.
The person who is now a carpenter used to be a butcher.
Charles has never been a baker, Mr Darren Carpenter has never been a butcher and Mr Baker is not now a carpenter.
Can you determine their full names, along with their current and previous professions?
