Puzzle Test: Floors, Boxes, Scheduling and Matching

1. What is a reasoning puzzle?#

A puzzle gives a finite set of people or objects and several restrictions. Find an arrangement that obeys every restriction at the same time. Unlike a number series, you do not invent the rule: the supplied clues define it. A valid-looking arrangement that breaks one negative clue is wrong.

Common formats are floors, stacked boxes, days or months, comparison/ranking, distributions into groups and matching people with subjects, cities or professions. Seating puzzles have their own chapter; here the focus is order and assignment. Unless specified, do not assume equal group sizes, consecutive dates, a person’s gender or that every attribute is distinct. Read these conditions explicitly.

2. Build the right table before solving#

Identify four things: entities, positions, attributes and constraints. For a six-floor building draw six rows, with 6 at the top and 1 at the bottom. For a weekly schedule put Monday before Tuesday. For a person–subject puzzle use columns for day, person and subject. Mark a confirmed entry, a possible entry and an excluded entry differently.

Format	Best layout	First check
Floors	Vertical numbered rows	Lowest floor number and vacant floors
Boxes	Bottom-to-top numbered stack	Whether spaces are allowed
Days/months	Chronological rows	Which dates are available
Person–attribute matching	One row per slot, one column per attribute	Whether every attribute is used once
Group distribution	One column per group	Capacity and minimum/maximum conditions

Never put two confirmed people in a one-person slot. Once a person is fixed, remove that person from every other position. If two different subjects are required, do not assign the same subject twice.

3. Translate clue language accurately#

Immediately above/below means one position away. Two floors above means a position difference of 2, so one floor lies between. Two people between means a difference of 3 when every position is occupied. “A is above B” gives a direction but no fixed distance. “A is not immediately above B” excludes one position, not every position above B.

“Either end” means the first or last permitted slot. “Neither end” excludes both. “Before” is normally non-immediate; “immediately before” is immediate. “At least two between” means a position difference of at least 3. “At most two between” permits differences 1, 2 and 3. “Only one between A and B” does not specify which is first.

Use simple equations when helpful. With bottom-to-top positions, A two above B is p(A) = p(B) + 2. Exactly k occupied positions between A and B means |p(A) − p(B)| = k + 1. The occupied-position qualification matters if vacant floors are allowed.

4. Floor puzzles: full worked example#

Five people A–E live on floors 1–5, one per floor; floor 1 is lowest. Clues: C is on floor 5. A is immediately below C. B is two floors below A. D is below B.

1. Fix C on 5.
2. A is immediately below, so A is on 4.
3. B is two floors below 4, hence B is on 2. Floor 3 lies between A and B.
4. D is below floor 2, so only floor 1 remains for D.
5. E takes the remaining floor 3.

Final top-to-bottom order: C–A–E–B–D. E lives immediately above B. One person lives between A and B. Recheck all four clues; an unused name is placed only after the remaining slot is established.

5. Box stacks and linked blocks#

A stack uses the same arithmetic as floors, but its wording often says “from top” and “from bottom”. For n boxes, position from top + position from bottom = n + 1. The third box from the top of a seven-box stack is fifth from the bottom.

If A is immediately above B, keep the block B–A when writing bottom-to-top. If C is immediately above A, the block becomes B–A–C. A block can slide among possible positions until another clue anchors it. Do not reverse the block when you change the drawing direction.

Example: P, Q, R, S, T are stacked. P is bottommost; Q is immediately above P; R is immediately above Q; T is immediately above R. S must be topmost. Bottom-to-top: P–Q–R–T–S. There are two boxes between Q and S. A clue about empty spaces must be represented separately; “two boxes between” is not necessarily “two levels between” if gaps exist.

6. Day schedules and consecutive blocks#

List the allowed days first. If there is one event on each day Monday–Friday, the slots are consecutive calendar days. If only Monday, Wednesday and Friday are available, the next listed slot after Monday is Wednesday, but the next calendar day is Tuesday. Never replace one meaning with the other.

Worked example: A–E present Monday–Friday once each. B presents Monday; D presents immediately after B; A presents two days after D; E presents before A but after D. Therefore B is Monday, D Tuesday, A Thursday, E Wednesday and C Friday. The order is B–D–E–A–C.

“Before A but after D” is a bounded interval. If more than one free slot remains in that interval, retain the alternatives. It is unsafe to select the nearest slot without an immediate clue.

7. Month, date and multi-slot schedules#

A calendar month difference is not a fixed number of days. January to March is two month steps, with February between. If a question lists January, March and June only, March is the second listed slot; it is not the second month of the year. Use the clue’s calendar unit.

When two events happen each month, use a two-column table such as early/late or 5th/20th. Specify whether “immediately before” means the previous chronological event or the previous day. Do not assume every month has 30 days or turn an unspecified year into a leap year.

For mixed date clues, first filter impossible dates, then connect people. A date such as 31 April is invalid; whether 29 February exists depends on the year. Calendar arithmetic is covered separately; a scheduling puzzle usually needs only the dates actually provided.

8. Person–subject matching: solve two dimensions#

Suppose A, B and C present Monday–Wednesday. Subjects P, Q and R are each used once. A presents Monday. B presents R. Q is presented immediately before R. C does not present Q.

A is already Monday. B can be Tuesday or Wednesday. If B were Wednesday, Q would be Tuesday, which must then belong to C; that violates C’s clue. Thus B is Tuesday with R. A is Monday with Q, and C is Wednesday with P.

Day	Person	Subject
Monday	A	Q
Tuesday	B	R
Wednesday	C	P

The clue “B presents R” links person to subject, not to a particular day. It becomes a day assignment only when one of those entries is positioned. Keep such links together while testing cases.

9. Comparison, ranking and group distribution#

For “A is taller than B; B is taller than C”, write A > B > C. This compares relative rank; it does not supply actual heights. With only A > B and A > C, the order of B and C remains unknown. “Second tallest” becomes a fixed slot only after the number of people and treatment of ties are known.

For distributions into teams, record each team’s capacity first. If six people must be divided into teams of three, filling one team determines the other. “A and B are not together” is an exclusion, while “A is with B” is a block. “At least one woman in each team” gives a minimum, not exactly one. Only use gender labels supplied by the question.

Example: A–F form two teams of three. A and B are together; C cannot be with A; D is with C; E is with A. The teams must be A–B–E and C–D–F. Team names can be interchangeable unless anchored by another clue.

10. How to branch without losing track#

Start with fixed positions, large gaps and blocks: these usually restrict more cases. Place uncertain blocks in separate labelled cases. Copy only the information shared by all cases into a common table. Apply negative clues as soon as the relevant position becomes known.

Example: in five slots, A is two positions before B and C is immediately after B. The A–B–C placements can be (1,3,4) or (2,4,5); (3,5,6) is impossible. If D occupies slot 1, the first case fails because A cannot share it. The second case survives. The remaining person fills slot 3.

When a branch fails, record the exact contradiction: duplicate slot, repeated attribute, unavailable position or broken clue. This prevents returning to the same failed case. If you get no solutions, first check orientation and the difference-versus-between rule before deciding the question is faulty.

11. Unique solution versus definite answer#

A full arrangement can be non-unique while one answer is certain. With A fixed in position 1 and B in position 2, C and D may swap in positions 3 and 4. A’s immediate successor is definitely B; the last person cannot be determined.

For “must be true”, a statement must hold in every valid arrangement. For “could be true”, one valid arrangement is sufficient. “Cannot be true” means none permits it. Never use a single trial arrangement as proof that a statement must hold.

For data sufficiency, test statement I alone, II alone, then both if needed. Do not carry information from the first trial into the second. Read the answer-option scheme because exams may label these combinations differently.

12. Common traps and correction checks#

• Reverse orientation: label top/bottom or earliest/latest before placing names.
• Wrong gap: k intervening occupied slots means k + 1 position steps.
• Invented immediacy: “above” and “before” do not mean “immediately”.
• Repeated attributes: a one-to-one assignment uses every named attribute once.
• Incomplete negative clues: check “not”, “neither”, “at most” and “at least” separately.
• Answering the wrong entity: the question may ask for a subject, not the presenter.
• Assuming uniqueness: search for a surviving alternative when a question is not fully anchored.
• Mixing cases: a person assigned in Case 1 cannot be imported into Case 2 without deduction.

13. An efficient exam routine#

Read the setup, draw the table, translate clues, place anchors, connect blocks, test cases and finally answer all questions from the same solution. Reuse the diagram for a five-question set. Mark the exact person or attribute mentioned in each question before reading the options.

For timed practice, record time spent on setup separately from time spent answering. If the table remains highly open, move to another set and return later. Review a wrong answer by locating the first violated clue, not by memorising the final order. Progress from floors and boxes to schedules, then to multi-attribute puzzles.

14. Quick revision card#

Position difference = intervening occupied positions + 1. Top rank + bottom rank = total + 1. A fixed link between two entities is not a fixed position. A chronological slot is not necessarily a consecutive calendar day. One surviving example proves possibility; all surviving cases are needed to prove necessity. Read every clue again after completing the table.
