20 of 53 cards from the Analytical Reasoning deck — real questions with worked answers.

1. In analytical reasoning, what is a 'seating arrangement' problem?

   A problem in which people or objects must be positioned in a fixed order (in a row, around a circular/rectangular table, etc.) based on given relational clues about who sits where.

2. In a linear (row) seating arrangement, what two facing directions are normally assumed unless stated, and how do left/right work?

   All persons typically face the same direction (e.g., north). For someone facing north, their left is west and right is east; the arranger's left/right is from the reader's perspective only when specified.

3. In a circular arrangement, how is left/right determined when people face the CENTRE versus face OUTWARD?

   Facing centre: a person's left is clockwise and right is anticlockwise. Facing outward: a person's left is anticlockwise and right is clockwise (directions reverse).

4. How many distinct ways can n people be seated around a circular table (rotations treated as identical)?

   (n - 1)! ways, because fixing one person removes equivalent rotations.

5. In seating problems, what does the clue 'A sits immediately to the right of B' mean versus 'A sits to the right of B'?

   'Immediately to the right' means A is adjacent, the next seat. 'To the right' means A is somewhere on B's right side, not necessarily adjacent.

6. What is the recommended first step when solving a seating arrangement puzzle?

   Start with the most definite/fixed clue (an absolute position) to anchor the diagram, then place relative clues around that anchor.

7. What defines an 'ordering and sequencing' problem?

   A problem requiring items to be placed in a single linear order based on comparative clues (taller/shorter, earlier/later, higher/lower) such as ranking by height, age, time, or score.

8. In sequencing, what is the difference between a 'fixed' clue and a 'relative' clue?

   A fixed clue gives an absolute position (e.g., 'C is third'); a relative clue gives order between items (e.g., 'A is before B') without pinning exact positions.

9. In an ordering problem, what does 'A is immediately before B' add beyond 'A is before B'?

   'Immediately before' means A and B are consecutive with no item between them; 'before' only fixes that A precedes B at some distance.

10. In sequencing, how should a 'block' clue like 'A, B, C sit together in that order' be handled?

    Treat A-B-C as a single fixed unit/block, place the block as a whole, then fit remaining items around it.

11. What is a 'grouping and selection' problem in analytical reasoning?

    A problem where items must be divided into groups or a subset must be selected/excluded subject to compatibility and conflict rules (e.g., 'if X is chosen, Y is not').

12. In grouping problems, what does a 'conditional inclusion' rule such as 'If P is selected then Q must be selected' imply by contrapositive?

    By contrapositive: if Q is NOT selected, then P is NOT selected. The rule does not say anything about P when Q is selected.

13. In grouping/selection, what does an 'exclusivity' rule like 'P and Q cannot be in the same group' mean?

    P and Q are mutually exclusive within a group; at most one of them can appear in any single group together.

14. In a grouping puzzle, what is the role of 'distribution constraints' (e.g., each group has exactly 3 members)?

    They fix the size of each group, limiting how many items can be placed and forcing certain items in or out once others are assigned.

15. What is a 'matching and assignment' problem?

    A problem that pairs elements of one set with elements of another (e.g., people to cars, students to subjects) where each match is unique based on given clues.

16. What tool is most effective for solving matching/assignment problems with multiple attributes?

    A matrix/grid (table) where rows and columns represent the sets, marking confirmed matches with a tick and impossibilities with a cross.

17. In a matching grid, once a confirmed match (tick) is placed in a cell, what must be done to the rest of that row and column?

    All other cells in that same row and column must be crossed out, since each element matches exactly one other.

18. What is an 'if-then' (conditional) statement, and which part is which?

    A statement of the form 'If P then Q.' P is the antecedent (hypothesis/condition); Q is the consequent (conclusion/result).

19. For the conditional 'If P then Q,' state its converse.

    The converse is 'If Q then P' — it is NOT logically equivalent to the original.

20. For the conditional 'If P then Q,' state its inverse.

    The inverse is 'If not P then not Q' — it is NOT logically equivalent to the original.
