Logical Reasoning
Set-based reasoning: arrangements, routes, games & tournaments, binary logic. Usually 4–5 questions per set.
Key Concepts
Linear / circular arrangements: list all constraints, use elimination to fix positions
Floor / grid puzzles: use a table — rows for floors/seats, columns for attributes
Binary logic (truth-teller/liar): assume each person is truth-teller, check for contradictions
Tournament grids: create a match results matrix and fill from given clues
Strategy Tips
Draw a fresh diagram for each question in a set — don't re-use a dirty one
If a clue seems contradictory, you've made a wrong assumption earlier — trace back
In CAT DILR, 1–2 sets are easy, 1–2 are hard. Identify and attempt easy sets first
