Reasoning Ability: Turning Clues into Fixed Arrangements
Reasoning Ability in the Karnataka Bank Clerk online test checks how quickly you convert a set of clues into a fixed arrangement or a valid conclusion. The section is scoring but clock-hungry: one wrong start on a puzzle set can cost five marks at once, so what is really tested is structured elimination, not intuition.
What the paper actually asks
- Puzzle and seating arrangement sets - circular and square (facing centre or facing outside), linear rows, floor-based puzzles, month/year scheduling and box stacking - usually carrying the largest share of marks.
- Syllogism with possibility conclusions, coded and direct inequality, blood relations, direction and distance, order-ranking, alphanumeric series, coding-decoding, word formation and data sufficiency.
Rules worth memorising
- Left and right in a circle are judged from the person's own facing: facing the centre, that person's left is clockwise; facing outward, the left is anticlockwise.
- Syllogism: All A are B plus All B are C gives All A are C. A "possibility" conclusion is true unless the statements positively rule it out.
- Coded inequality: chain the symbols (A ≥ B > C means A > C) and never reverse a chain.
Worked example
Five people P, Q, R, S, T sit in a row facing north. Q is at the extreme right. T is second to the left of Q. R sits immediately right of T. S is second to the left of R. Who is at the left end? Number the seats 1–5 from the left. Q = 5. Second to the left of Q is seat 3, so T = 3. Immediately right of T is seat 4, so R = 4. Second to the left of R is seat 2, so S = 2. The only empty seat, 1, takes P. Order: P S T R Q - P is at the left end.
Traps that cost marks
Reading "second to the left" as "immediate left"; ignoring an outward-facing condition and mirroring the whole arrangement; abandoning a puzzle after one wrong case instead of testing two cases and eliminating one; marking a syllogism conclusion that is merely possible as definitely true.
