General Intelligence & Reasoning
Coding-Decoding, Analogies, Series, Syllogisms, Blood Relations & Non-Verbal
This is the General Intelligence & Reasoning syllabus taught for RRB JE Junior Engineer. Each topic opens as a full chapter — theory, worked examples and the traps that paper actually uses.
Topics in General Intelligence & Reasoning
- Analogy & ClassificationIdentifying relationships and odd-one-out among semantic, symbolic, number and figural elements.
- Blood Relations & Direction SenseFamily relationship puzzles and direction-distance tracking using position and turns.
- Clocks & CalendarsAngle and time problems on clocks and finding days using odd-days and leap-year concepts.
- Coding-DecodingEncoding and decoding of words and numbers using letter shifts, patterns and symbolic operations.
- Cubes & DiceProblems on dice faces, opposite faces and counting painted or cut cubes.
- Reasoning Data SufficiencyDecide whether statement (I), (II), either, both, or neither suffice to answer a reasoning question — ranking and direction stems, not quantitative DS.
- Embedded Figures & Figure CountingFind figure X embedded in an option with rotation not allowed; complete a missing-figure pattern; count triangles or squares in a line figure, including composites.
- Coded InequalityRead a chain of P > Q ≥ R = S < T (or a coded-symbol key) and decide which conclusions definitely follow.
- Machine Input–OutputName the hidden rewriting rule on a token line (arrangement, circular or block shift, or number operation) from two consecutive machine steps, then predict a later step or the…
- Mathematical OperationsSolving equations after interchanging mathematical signs and numbers based on given rules.
- Mirror & Water ImagesIdentifying the reflection of figures, letters and numbers in mirror and water surfaces.
- Non-Verbal ReasoningFigure-based reasoning covering figural series, analogy, classification and pattern completion.
- Order & RankingDetermining positions of people or objects from left, right, top or bottom in an arrangement.
- Paper Folding & CuttingPredicting the appearance of paper after folding, punching and unfolding, a spatial reasoning skill.
- Logical Puzzles & ArrangementsComplex puzzles including scheduling, floor, box and category-based arrangement problems.
- Seating Arrangement & PuzzlesArranging people or items in linear, circular and complex seating and ordering puzzles.
- Series (Number, Alphabet & Figural)Finding the missing or next term in number, alphabet, alphanumeric and figural series.
- Statement & Conclusion / AssumptionEvaluating whether conclusions, assumptions or inferences logically follow from given statements.
- SyllogismDrawing valid conclusions from given statements using Venn-diagram-based logical deduction.
- Venn DiagramsRepresenting relationships between groups and solving set-based logical questions using diagrams.
- Dictionary Order & Word BuildingArrange words as in a dictionary; form one meaningful English word from given letters; count letter-pairs in a word that have as many letters between them as in the alphabet.
