Shared with IBPS PO's own Reasoning Ability subject.

📊 Prelims: 35 Q / 35 marks · Mains: 50 Q / 50 marks

How toppers play this section

The identical banking-family reasoning syllabus as IBPS PO — puzzles and seating arrangement dominate across both stages.

Chapters

Built to the NIACL AO blueprint — notes, shortcuts, solved PYQ-style examples and practice in every chapter.

1Puzzles & Seating ArrangementThe single largest block in the reasoning section — 40–55% of every IBPS PO paper. Master the six puzzle frames (linear, circular, floor, box, scheduling and comparison), learn to separate definite clues from floating ones, and a 5-question set that scares half the hall collapses into a 4-minute, 5-mark gift.⏱ 26 min read

2Syllogism (incl. New Pattern)3–5 near-certain marks in Prelims and a staple new-pattern set in Mains. Statements are assumed true — even absurd ones — and you test whether a conclusion MUST follow. Master the minimal-Venn method, the "possibility" cases, and the reverse/coded twists IBPS now favours, and syllogism becomes the fastest reasoning block after simplification.⏱ 20 min read

3Inequalities — Direct & Coded3–5 of the most mechanical marks in the reasoning section — pure symbol-chaining with one golden rule. Learn how relations combine, when a conclusion is definite vs an "either–or", and how to decode the coded (symbol-substitution) version, and inequalities become sub-20-second gifts you never get wrong.⏱ 18 min read

4Coding–Decoding (New Pattern)The bank version isn't the old letter-shift — it's the sentence-based "new pattern" where each word is a code and you deduce the mapping across several sentences. Learn the intersection method, and the 3–5 questions per paper become a fast, logical set rather than a guessing game.⏱ 19 min read

5Blood Relations2–3 fast marks that a family tree turns from confusing to trivial. Learn the diagram notation, the "read the sentence backwards" trick for pointing-based puzzles, and the coded-relation symbols, and blood relations become a reliable 30-second scorer in both Prelims and Mains.⏱ 17 min read

6Direction & Distance2–3 marks where a person walks a path and you track where they end up and how far. A quick sketch on a compass and the Pythagorean shortcut turn these into 30-second wins. Learn the turn rules, the coded-direction twist, and the shortest-distance trick, and direction becomes free marks.⏱ 16 min read

7Order & Ranking2–3 marks about positions in a row or a rank order — "Ram is 7th from the left and 11th from the right, how many in the row?" One formula and a clean line-diagram make these near-instant. Learn the total-count formula, the overlap trap, and the min/max variant, and ranking becomes free.⏱ 15 min read

8Alphanumeric & Alphabet Series3–5 quick Prelims marks from a mixed string of letters, numbers and symbols — questions about what follows what, counts, and pattern positions. The EJOTY landmarks and a "read the exact condition" habit make these near-instant. Learn the question types and the counting traps, and this becomes reliable, fast scoring.⏱ 15 min read

9Data Sufficiency (Reasoning)3–5 marks where you decide whether the given information is enough — not what the answer is. The trap is solving when you only need to judge sufficiency. Learn the fixed 5-option framework, the "evaluate each statement alone first" rule, and how to avoid the assumption trap, and DS becomes fast, high-accuracy marks.⏱ 17 min read

10Input–Output (Machine)A Mains-only 5-mark set that scares people because it looks like magic — but it's just a fixed rule applied step by step. Learn to find the rule from the first two steps, distinguish shifting from arithmetic machines, and read only the step a question asks about, and this becomes a clean, high-return block.⏱ 19 min read

11Logical & Verbal ReasoningThe 5–7 mark "verbal" block that lifts Mains reasoning scores — statement & assumption, inference, argument strength, cause & effect, and course of action. It looks subjective but runs on hard rules: stay inside the statement, reject the too-strong option, and never import outside knowledge. Learn the rules and it becomes as objective as syllogism.⏱ 21 min read
