A note on these questions
These are practice questions written in IBPS/SBI style by the Bryn Flow team, covering the correct syllabus concepts for each chapter — they are not reproduced from official past-year papers. Concept notes are written for exam revision specifically, condensed to the formulas and shortcuts that actually get tested, not general encyclopedia-style explanations.
Module 1 — Quantitative Aptitude
1 Simplification & Approximation
Simplification questions follow the standard order of operations (VBODMAS: Vinculum, Brackets, Of, Division, Multiplication, Addition, Subtraction). In banking exams these are almost always solvable quickly once you have squares up to 30, cubes up to 20, and common percentage-to-fraction equivalents (like 12.5% = 1/8, 16.67% = 1/6) memorized cold.
Approximation questions ask for a close value, not an exact one — round each number to the nearest convenient value (e.g. 39.98% → 40%, 250.02 → 250) before calculating, since the answer options are always spaced far enough apart that rounding won't cause you to pick the wrong one.
2 Number Series
Most series fall into a handful of patterns: constant or increasing/decreasing common difference, common ratio (×2, ×3, ...), squares/cubes (with a small offset like n²+1 or n²−1), sums of two interleaved series, or a "difference of differences" (second-order) pattern where the differences themselves form a series.
Wrong number series questions give you 7-8 terms following a pattern and ask which one breaks it — write out the differences or ratios between consecutive terms first; the pattern almost always becomes obvious within the first three gaps.
3 Quadratic Equations
Banking exams rarely ask you to just solve an equation — the classic format gives two equations (in x and y) and asks you to compare the roots to decide whether x > y, x < y, x = y, x ≥ y, x ≤ y, or whether the relationship can't be determined. Solve both equations by factorization, then compare every root of x against every root of y — if the comparison isn't consistent across all pairs (e.g. x > y for one pair but x = y for another), the answer is one of the combined relations (≥ or ≤), not a strict inequality.
For ax² + bx + c = 0, the sum of roots is −b/a and the product of roots is c/a — useful for checking factorization quickly without fully re-solving.
4 Data Interpretation
DI sets (tables, bar/line/pie charts, or caselets) mostly test ratio, percentage, and average calculations layered on top of reading the data correctly. In a pie chart, a sector's percentage share is (sector angle / 360°) × 100. Percentage change is ((new − old) / old) × 100.
The single biggest time-saver in DI is approximation: unless a question explicitly asks for an exact value, round the numbers in the chart before computing — most DI questions are designed so the options are spaced far enough apart that this never costs you the right answer.
Module 2 — Reasoning Ability
5 Puzzles & Seating Arrangement
The heaviest-weighted reasoning topic in most banking exams. Arrangements come in a few flavors: linear rows (facing north or south), circular or rectangular tables (facing the center or facing outward), and multi-floor or multi-box puzzles. "Left" and "right" in a row puzzle are always from each seated person's own perspective as they face the stated direction, not the reader's — this is the single most common trap.
Strategy: scan every clue first and start placing people from whichever clue gives the most fixed, unambiguous information (an extreme end, a fixed position number), then work outward. Draw the arrangement rather than tracking it mentally.
6 Syllogism
Syllogism gives you two or more statements ("All A are B", "Some A are B", "No A are B") and one or more conclusions, and asks which conclusions logically follow. The safest method is drawing Venn diagrams for every possible case the statements allow, and checking whether a conclusion holds in every case — not just the one that seems most likely.
A frequent trap: "Some A are B" and "Some B are C" together do not guarantee "Some A are C" — the "some" portions of B involved in each statement aren't necessarily the same elements.
7 Coding-Decoding
Coding-decoding questions replace letters, numbers, or symbols with other letters, numbers, or symbols under a hidden rule, and ask you to apply that same rule to a new word. Common rule types: shifting each letter forward or backward by a fixed number of places, replacing a letter with its position number in the alphabet, and reflecting each letter to its "opposite" position (A↔Z, B↔Y, C↔X, ... — found as 27 − position).
Always verify your rule against every letter of the given example before applying it to the new word — a rule that works for the first two letters but not the third isn't the real rule.
8 Blood Relations
Blood relation questions are solved by building a small family tree from the statements, one relation at a time. Watch for phrases like "only son" or "no sisters" — they pin down a relationship exactly (an "only son" of your grandfather, if not you, must be your father) and are usually the key to unlocking the whole puzzle.
Reading the sentence from the innermost clause outward, and drawing the tree as you go (using generation levels: grandparents above parents above the person), avoids the confusion that comes from trying to hold multi-generation relations in your head.
