Top four people (Posted on 2008-10-18) Difficulty: 2 of 5
Top four people and their occupation were listed in a magazine.
 place   1st name    surname    occupation
-------------------------------------------
   1      Isaac      Newtune    welder
   2      Albert     Eyeline    gardener
   3      Marie      Curious    cleaner
   4      Paul       Darling    bricklayer
-------------------------------------------
However, only one entry in each of the three righmost columns was correctly positioned. The following facts were true:
(1) Albert was two places above the bricklayer.
(2) Darling was one place below Paul.
(3) Curious was two places below the welder.

Find the first name, surname and occupation for each position.

Using (1), Albert is at 1 or 2.

If he is at 1, then from (3), Paul is at 2 or 3. However, with Paul at 2 (and Darling at 3), from (2), Curious can only be at 4 and so it is not possible to find just one correct entry in the Surname column (Newtune and Eyeline must be both correct or both incorrect).

If Paul is at 3 (with Darling at 4), then from (2), Curious can only be at 3. This gives both Curious and Darling correct (invalid). So Albert must be at 2 (with the bricklayer at 4).

From (3), Paul can be at 1 or 3. However, if Paul is at 3 (with Darling at 4), then both Curious and Darling are correct (invalid). So Paul is at 1 (with Darling at 2).

From (2), Curious can now be at 3 or 4, but if Curious is at 3 (with the welder at 1) then both the welder and bricklayer are correct (invalid). This gives Curious at 4 (with the welder at 2).

For the 1st Name, only Albert is correct at 2, Marie can only be at 4 and so Isaac is at 3.

In the Surname column, only Newtune can be correct at 1, so Eyeline is at 3. The bricklayer must be the correct speciality at 4, the cleaner can only be at 1 and so the gardener is at 3.
        1st Name	Surname	Occupation
--------------------------------------
1	Paul	Newtune	Cleaner
2	Albert	Darling	Welder
3	Isaac	Eyeline	Gardener
4	Marie	Curious	Bricklayer
--------------------------------------
