Analytical and Logical Reasoning: Draw, Then Decide
Question families
Analytical and Logical Reasoning rewards structure. Expect syllogisms, blood relations, direction sense, seating and floor arrangements, ranking and ordering, coding–decoding, number and letter series, analogies and odd-one-out, statement–assumption and statement–conclusion, cause–effect, and short puzzles with three to five conditions.
Traps designed into the paper
- Syllogism: "All A are B" does not give "All B are A"; "Some A are B" does not give "Some B are not A". The true negative of "All A are B" is "Some A are not B".
- Blood relations: the person asking the question is often different from the person described in the chain. Draw the family tree and re-read the final line.
- Arrangements: "immediately left of" differs from "left of", and a person facing south has left and right reversed.
- Statement–assumption: an assumption must be necessary for the statement, not merely plausible.
- Series: test whether two interleaved series are running side by side before hunting exotic patterns.
Worked example
"All pens are books. Some books are red." Nothing follows about pens being red, because the red books may lie outside the pen set. Draw two overlapping circles and try to construct a counter-diagram for each option. If a valid counter-diagram exists, that conclusion does not follow.
Rule of thumb
Draw every question. Never carry an arrangement in your head past three conditions - a small table with fixed positions exposes contradictions early and saves time on the conditions that follow.
