COMSATS Admission Test Analytical Reasoning flashcards — 51 questions with answers
What is statement-based reasoning in analytical reasoning?
A reasoning type where you are given one or more statements (premises) assumed to be true and must determine which conclusions, assumptions, or inferences logically follow from them — regardless of real-world truth.
In statement-and-assumption questions, what is an 'assumption'?
An unstated idea that is taken for granted — something the speaker/writer must believe to be true for the statement to make sense. A valid assumption is implicit, not explicitly stated.
How do you distinguish an 'inference' from a 'conclusion' in statement-based reasoning?
A conclusion is a summary/decision directly drawn from the stated facts; an inference is information not stated but logically derivable from the given facts. Inferences go one step beyond what is written; conclusions restate what the facts establish.
What is a 'course of action' question in statement-based reasoning?
A question giving a problem statement plus suggested actions; you decide which action logically and practically follows to solve or improve the situation. A valid course of action must address the problem and be feasible.
What is a syllogism?
A form of deductive reasoning with two premises and a conclusion, where the conclusion must necessarily follow from the premises if they are true (e.g., All A are B; All B are C; therefore All A are C).
In syllogisms, what does the term 'All A are B' mean for the relationship between A and B?
Every member of set A is contained within set B (A is a subset of B), but not every B need be A. It is a universal affirmative (Type A) statement.
What are the four standard categorical (syllogism) proposition types and their codes?
A = Universal Affirmative (All S are P); E = Universal Negative (No S is P); I = Particular Affirmative (Some S are P); O = Particular Negative (Some S are not P).
In syllogism Venn-diagram solving, when is a conclusion considered 'definitely true'?
When the conclusion holds in every possible Venn diagram that can be drawn for the given premises. If even one valid diagram contradicts it, the conclusion does not definitely follow.
In syllogisms, what does 'Some A are B' imply about 'Some B are A'?
'Some A are B' always implies 'Some B are A' — the 'Some' (particular affirmative) relationship is reversible/convertible.
In syllogisms, can two negative premises (e.g., No A is B; No B is C) yield a definite conclusion?
No. From two universal negative premises, no definite conclusion can be drawn between the end terms.
What is the 'either-or' (complementary pair) rule in syllogisms?
When two conclusions individually do not follow but together they exhaust all possibilities (same subject and predicate, one positive and one negative, with 'Some' involved), then 'either I or II follows' is the answer.
Define a cause-and-effect relationship in analytical reasoning.
A relationship where one event (the cause) directly produces or leads to another event (the effect). The cause precedes the effect in time and is responsible for bringing it about.
In cause-and-effect questions, what are the typical answer categories for two given statements?
(1) Statement I is cause, II is effect; (2) Statement II is cause, I is effect; (3) Both are independent causes; (4) Both are effects of a common cause; (5) Both are effects of independent causes.
In cause-and-effect reasoning, how do you identify which statement is the cause?
The cause is the event that occurs first in time and triggers the other. The effect is the resulting consequence. The earlier, triggering event is the cause.
What is meant by 'both events are effects of a common cause' in cause-and-effect questions?
Neither given event causes the other; instead, some third, unstated factor produces both events independently (e.g., both 'flooded roads' and 'crop damage' caused by heavy rain).
What is a key trap to avoid in cause-and-effect reasoning?
Correlation is not causation — two events occurring together or in sequence do not necessarily mean one caused the other. They may share a common cause or be coincidental.
What is a seating arrangement problem in analytical reasoning?
A puzzle where people/objects must be placed in positions (a row, circle, table, etc.) according to given conditions, and you deduce the exact ordering or who sits where.
In a circular seating arrangement, how do directions 'left' and 'right' work when people face the center?
When everyone faces the center, a person's left and right are opposite to the observer's: going clockwise corresponds to each person's right-to-left direction. (To a person facing center, their right hand points clockwise.)
In circular seating with people facing the center, which way is clockwise relative to each person?
Clockwise movement corresponds to moving toward each person's left side (since they face inward), so their right is the anticlockwise direction.
In a linear (row) seating arrangement where all face north, how do left and right map to the observer?
When all face north, each person's left is the observer's left and each person's right is the observer's right (same as the reader's view).

In linear seating where people face south, how do their left and right relate to the observer's view?
When facing south, each person's left becomes the observer's right and their right becomes the observer's left (directions are reversed).
In seating arrangements, what does it mean if two people are 'facing each other' across a rectangular table?
They sit on opposite sides of the table directly across from one another, so one's left side aligns with the other's right side.
What is the first step to solve a seating arrangement puzzle efficiently?
Identify and place the most definite/fixed clue first (an absolute position), then add relative clues around it, keeping flexible clues for last.
What is an ordering and ranking problem in analytical reasoning?
A puzzle where items or people are arranged in a sequence based on comparative attributes (height, age, marks, etc.) and you determine relative or absolute positions/ranks.
In ranking problems, if a person is 7th from the top and 11th from the bottom in a row, how many people are there in total?
Total = (position from top) + (position from bottom) − 1 = 7 + 11 − 1 = 17 people.
What is the formula to find a person's rank from the bottom given their rank from the top and the total number?
Rank from bottom = (Total number of people) − (Rank from top) + 1.
In a row of n people, if a person is at position r from the left, what is their position from the right?
Position from right = n − r + 1.
In ordering problems, how do you interpret 'A is taller than B but shorter than C'?
It gives the order C > A > B in height (C tallest, then A, then B). Chain comparisons into a single ordered sequence.
In ranking puzzles, how many people are between two given positions counted from the same end?
Number between = (larger position − smaller position) − 1, when both positions are counted from the same side.
What is a grouping and selection (team formation) problem?
A puzzle where you must form groups/teams from a set of items or people subject to inclusion/exclusion conditions (e.g., 'if A is selected, B cannot be'), and determine valid combinations.
In grouping problems, what does a condition 'A and B cannot be in the same group' require?
Any valid group containing A must exclude B, and any group containing B must exclude A — they are mutually exclusive within a single group.
In selection problems, how do you handle a conditional clue 'If X is selected then Y must be selected'?
Whenever X is in, Y must also be in. By contrapositive, if Y is NOT selected, then X cannot be selected either.
What technique helps systematically solve grouping/selection puzzles?
List all constraints, apply elimination by testing each option against every condition, and use a table or contrapositive logic to rule out invalid combinations.
What are conditional constraints in analytical reasoning puzzles?
Rules of the form 'if-then' that restrict arrangements/selections — they activate only when a condition is met, governing which placements or choices are permitted.
What is the contrapositive of 'If P then Q', and why is it useful in constraint puzzles?
The contrapositive is 'If not Q then not P', which is logically equivalent to the original. It lets you reason backward from a negated conclusion to eliminate possibilities.
In conditional constraint logic, does 'If P then Q' mean 'If Q then P'?
No. 'If Q then P' is the converse and is NOT logically equivalent. Q can be true for reasons other than P, so the converse may be false.
What is a 'biconditional' constraint and how is it written?
A constraint where two statements imply each other: 'P if and only if Q' (P ⇔ Q). P is true exactly when Q is true; both must share the same truth value.
What is letter coding in analytical reasoning?
A coding type where letters of a word are replaced by other letters according to a pattern (e.g., shifting each letter forward/backward by a fixed number) to form a code.
In letter coding, if CAT is coded as DBU, what is the rule?
Each letter is shifted forward by 1 position in the alphabet (C→D, A→B, T→U). The rule is +1 letter shift.
In letter coding, what are the alphabet position numbers of A, M, and Z?
A = 1, M = 13, Z = 26. Knowing these anchors helps compute forward/backward letter shifts quickly.
What is the 'opposite letter' (EJOTY-type complement) rule in letter coding?
Each letter pairs with its mirror from the other end where positions sum to 27: A↔Z, B↔Y, C↔X, etc. (position + opposite position = 27).
What is number coding in analytical reasoning?
A coding type where words/letters are assigned numerical codes (or numbers are coded as other numbers/letters) according to a rule you must discover and apply.
In number coding, if each letter is coded by its alphabetical position, what is the code for the word 'BAD'?
B=2, A=1, D=4, so BAD is coded as 2-1-4.
What is a common technique to crack number coding where a whole word maps to a number?
Look for relationships such as sum of letter positions, product, number of letters times a factor, or a positional value pattern, then test it against the given examples.
What is symbol substitution in analytical reasoning?
A method where mathematical operators or relationships are replaced by symbols/letters (e.g., '+' means '×'), and you re-substitute the real operations to evaluate or compare expressions.
In symbol substitution, if '+' means '÷', '−' means '+', '×' means '−', and '÷' means '×', evaluate 16 + 4 − 2.
Substitute: 16 ÷ 4 + 2 = 4 + 2 = 6.
What order of operations must be followed after substituting symbols in symbol-substitution problems?
Apply BODMAS/PEMDAS — Brackets, Orders (powers), Division/Multiplication (left to right), then Addition/Subtraction — using the substituted real operators.
What is a number series problem in analytical reasoning?
A sequence of numbers following a hidden pattern (arithmetic, geometric, squares, alternating, etc.) where you find the next term, the missing term, or the wrong term.
How do you identify an arithmetic vs a geometric number series?
Arithmetic: consecutive terms differ by a constant (common difference, +/−). Geometric: consecutive terms have a constant ratio (×/÷). Check differences first, then ratios.
What pattern fits the series 1, 4, 9, 16, 25, …?
Perfect squares: n² (1², 2², 3², 4², 5²). The next term is 36 (6²).
What is a letter series problem, and how is it solved?
A sequence of letters following a pattern based on alphabetical positions (fixed/alternating skips, mirror letters, or grouped shifts). Convert letters to position numbers, find the numeric pattern, then convert back to find the next letter.
