Circular seating, data sufficiency, Venn counting, input–output machines, floor puzzles and coded blood relations, generated and solved exactly by code.

Circular arrangement

Circular seating (round table, facing in and out)Read the circle clockwise as seen from above. Facing the centre, a person’s left is clockwise and right is anticlockwise; facing outward, left is anticlockwise. Fix one person first, then place neighbour and opposite clues.

Data sufficiency

Data sufficiency (two statements, five fixed options)Judge statement I alone, then statement II alone, and only then both together. A statement is sufficient only if it leaves exactly one possible answer; you never need to find the answer itself.

Venn diagrams

Venn diagram counting (two and three sets)Fill the Venn diagram from the inside out: the all-groups overlap first, then the two-group overlaps, then the “only” regions. Union = sum of singles − sum of pairs + triple.

Input–output

Input–output machine (one rule per step)Find the rule from Step 1 (which item moved, and to which end), check it on Step 2, then run it forward. Items not yet arranged keep their input order, so you can write any step directly.

Floor puzzles

Floor puzzles (one person per floor)Draw the floors from the bottom (1) to the top. Place top, bottom and fixed-floor clues first, then the “immediately above” and gap clues, and keep every branch until a clue removes it.

Blood relations (coded)

Coded blood relations (symbols for relations)Decode each symbol into one link, draw the family tree (+ for male, − for female, a horizontal line for a couple, a vertical line for a generation), then read the asked relation. If the asked person’s gender is never fixed, the answer is “cannot be determined”.
