Syllogism

A reasoning format in which two or more premises are given and a conclusion must be judged as definitely true, possibly true, or false. Candidates test validity using Venn diagrams rather than real-world belief.

Related: Venn Diagram Method, Either-Or Case
Venn Diagram Method

A technique for solving syllogisms and set-based puzzles by drawing circles for each category and checking whether a conclusion holds in every possible arrangement of overlapping regions.

Related: Syllogism, Possibility Case
Possibility Case

In syllogism questions, a conclusion stated as 'it is possible that...' is true when at least one valid diagram arrangement satisfies it, even if other arrangements contradict it.

Related: Venn Diagram Method, Either-Or Case
Either-Or Case

A pair of conclusions where exactly one must follow, because together they exhaust all arrangements and neither is individually certain. Both must share the same subject and predicate to qualify.

Related: Syllogism, Possibility Case
Input-Output Puzzle

A machine-based reasoning set where numbers or words are rearranged by a fixed hidden rule across steps. The candidate identifies the pattern from the given steps and predicts later stages.

Related: Coded Inequality, Seating Arrangement
Seating Arrangement

A puzzle requiring placement of people around a circle or in a row using clues about facing direction, adjacency, and relative position. Circular sets often assume all face the centre unless stated otherwise.

Related: Linear Arrangement, Floor Puzzle
Linear Arrangement

A seating puzzle where people sit in a single row or two parallel rows, with clues about ends, immediate neighbours, and how many persons sit between two named individuals.

Related: Seating Arrangement, Floor Puzzle
Floor Puzzle

A reasoning set where people or flats are assigned to numbered floors of a building, often with two flats per floor, using clues about who lives above, below, or beside whom.

Related: Seating Arrangement, Linear Arrangement
Coded Inequality

A question type where symbols such as @, #, and $ stand for comparison relations like greater than or not less than. Conclusions are tested by decoding the expression and chaining the relations.

Related: Input-Output Puzzle, Syllogism
Blood Relation

A puzzle describing family links through statements or a diagram, requiring the candidate to identify how two named persons are related, such as maternal uncle or sister-in-law.

Related: Direction Sense, Puzzle and Arrangement
Direction Sense

A reasoning question where a person moves through turns and distances, and the candidate must find final facing direction or shortest distance, often applying Pythagoras to right triangles.

Related: Blood Relation, Data Sufficiency
Data Sufficiency

A format where a question is followed by two or more statements, and the candidate judges only whether the data is enough to answer, without computing the actual answer.

Related: Direction Sense, Puzzle and Arrangement
Puzzle and Arrangement

The umbrella category covering distribution, scheduling, box-stacking, and floor sets in which entities must be assigned to attributes using interlocking constraints.

Related: Seating Arrangement, Data Sufficiency
Alphanumeric Series

A sequence mixing letters, digits, and symbols where questions ask for counts of a pattern, such as how many digits are immediately preceded by a consonant and followed by a symbol.

Related: Coding-Decoding, Input-Output Puzzle
Coding-Decoding

A question type in which words or sentences are written in a code under a rule, and the candidate must decode a new word or infer the rule from examples given.

Related: Alphanumeric Series, Coded Inequality
Data Interpretation

A set presenting numerical data as a table, bar chart, line graph, pie chart, or caselet, followed by questions requiring calculation of ratios, percentages, averages, or differences.

Related: Caselet, Percentage Change
Caselet

A data interpretation set given entirely as prose paragraphs rather than a chart, so the candidate must first extract and tabulate the numbers before answering the questions.

Related: Data Interpretation, Approximation
Percentage Change

The increase or decrease in a value expressed as a fraction of the original value, computed as (new minus old) divided by old, then multiplied by 100.

Related: Data Interpretation, Successive Discount
Successive Discount

Two or more discounts applied one after another on the reducing price, so the effective discount is less than the simple sum; for example 10% then 20% equals 28% overall.

Related: Percentage Change, Marked Price and Cost Price
Marked Price and Cost Price

Cost price is what a trader pays; marked price is the label price before discount. Profit or loss is always calculated on cost price unless the question states otherwise.

Related: Successive Discount, Simple and Compound Interest
Simple and Compound Interest

Simple interest is computed only on the principal each year; compound interest is computed on principal plus accumulated interest, growing faster and following a geometric pattern.

Related: Marked Price and Cost Price, Time, Speed and Distance
Time, Speed and Distance

The relation distance equals speed multiplied by time, extended to relative speed for trains and boats, and to average speed, which is total distance divided by total time.

Related: Boats and Streams, Simple and Compound Interest
Boats and Streams

Problems where downstream speed is boat speed plus current speed and upstream speed is boat speed minus current speed, so the two are averaged to find still-water speed.

Related: Time, Speed and Distance, Pipes and Cisterns
Pipes and Cisterns

A work-rate problem type in which inlet pipes fill and outlet pipes empty a tank, solved by adding rates as fractions of the tank filled per hour.

Related: Time and Work, Boats and Streams
Time and Work

Problems relating the rate of work of individuals or groups to the time taken, solved by converting each worker's capacity into a fraction of the job done per day.

Related: Pipes and Cisterns, Ratio and Proportion
Ratio and Proportion

A comparison of two quantities of the same kind, with proportion stating that two ratios are equal; widely used to split amounts and to set up mixture and partnership problems.

Related: Mixtures and Alligation, Time and Work
Mixtures and Alligation

A method using a cross-diagram to find the ratio in which two ingredients of different values must be mixed to obtain a desired mean value.

Related: Ratio and Proportion, Averages
Averages

The sum of all observations divided by their count; questions often involve how the average shifts when a value is added, removed, or replaced in a group.

Related: Mixtures and Alligation, Permutation and Combination
Permutation and Combination

Counting arrangements where order matters (permutation) versus selections where order does not matter (combination), applied to seating, committee, and word-formation questions.

Related: Probability, Averages
Probability

The number of favourable outcomes divided by total equally likely outcomes, often combined with combinations to count ways of drawing balls, cards, or committee members.

Related: Permutation and Combination, Data Interpretation
Quadratic Equation Comparison

A question giving two quadratic equations in x and y, requiring the candidate to find both roots of each and determine the relationship between x and y.

Related: Number Series, Approximation
Number Series

A sequence with a missing or wrong term, where the candidate identifies the underlying rule, such as differences, squares, cubes, or a mixed pattern, to supply the answer.

Related: Quadratic Equation Comparison, Approximation
Approximation

A simplification question where exact calculation is unnecessary and values are rounded to convenient numbers so the closest option can be chosen quickly.

Related: Number Series, Data Interpretation
Cloze Test

A passage with blanks, each to be filled by the option that fits the grammar and meaning of the surrounding sentence and the overall theme of the text.

Related: Reading Comprehension, Para Jumble
