The Weekly Warlock Wind-Up: Supermarkets (answer)

This week’s question:

In a supermarket queue of seven people, Mr Thompson is immediately in front of Ms Foster. Ms Edwards is between Mr Bailey and Mr Ford. Ms Davies is immediately behind Ms White and there are two people between Ms Davies and Mr Bailey. Mr Bailey is immediately behind Ms Foster. From the front of the queue, what is the order of the shoppers?

Answers after the break!

So the best way I found to do this was to look at each sentence in turn and try and construct the overall order piece by piece. Let’s take a look at some of what we know:

  • Mr Thompson is immediately in front of Ms Foster.
  • Ms Edwards is between Mr Bailey and Mr Ford.
  • Ms Davies is immediately behind Ms White.

Using just these facts we can assemble three sections of the overall puzzle (assuming the top of the list is the front end of the queue):

  1. Mr Thompson
  2. Ms Foster
  1. Mr Bailey
  2. Mrs Edwards
  3. Mr Ford
  1. Ms White
  2. Ms Davies

All that remains now is to order these sections correctly. We know from the question that Mr Bailey is behind Ms Foster, so that allows us to narrow it down to two sections:

  1. Mr Thompson
  2. Ms Foster
  3. Mr Bailey
  4. Mrs Edwards
  5. Mr Ford
  1. Ms White
  2. Ms Davies

Finally, we are told that there are two people between Ms Davies and Mr Bailey, so Ms Davies must be in front of Mr Thompson for that to work:

  1. Ms White
  2. Ms Davies
  3. Mr Thompson
  4. Ms Foster
  5. Mr Bailey
  6. Mrs Edwards
  7. Mr Ford

Hard to explain but perhaps not so hard to work out; how’d you do?

    Opps, when reading “Ms Edwards is between Mr Bailey and Mr Ford.” I just went with anywhere in between :(.

  2. Mishaweha Says:

    That’s more or less how I reasoned through it, though I think I lumped Thompson, Foster, and Bailey in one of my first steps.

    Nigel, I too thought at first that Ms. Edwards didn’t have to be directly between Mr. Bailey and Mr. Ford. However, when I assumed that, there was more than one solution. When I tried her directly in between, I only got one solution.

    I think what through me off was the fact the wording didn’t say ‘immediately’ or ‘directly’, which the other clues had said.
