RRB JE General Intelligence and Reasoning flashcards — 51 questions with answers
In Blood Relations, what does the phrase "only daughter of my mother" refer to?
It refers to the speaker herself (if female) or, when said about someone, identifies that female as the speaker's mother's single daughter.
What is the standard method to solve a Blood Relations problem stated in a single complex sentence?
Break the sentence into parts from the end, use symbols (+ for male, - for female), and draw a generation-wise family tree linking each relation step by step.
In Coding-Decoding, what is "letter-position coding"?
A method where each letter is replaced by its position number in the alphabet (A=1, B=2, ... Z=26) or vice versa.
What is the reverse alphabetical position (EJOTY-like) value of the letters A, E, J, O, T, Y, Z?
A=1, E=5, J=10, O=15, T=20, Y=25, Z=26 — useful anchor positions for quick letter-number coding.
In Coding-Decoding, what is the "opposite letter" of a given letter and how is it found?
The opposite letter sums to 27 with the original (A↔Z, B↔Y, C↔X...). Opposite letter = 27 minus the letter's position.
What are the three main types of Coding-Decoding in reasoning?
Letter coding (shifting letters), number/symbol coding (letters to numbers/symbols), and substitution coding (words replaced by other words).
In Direction Sense Test, what are the four cardinal and four ordinal directions?
Cardinal: North, South, East, West. Ordinal (intercardinal): North-East, North-West, South-East, South-West.
In a Direction Sense Test, if you face North and turn right, then right again, which direction do you face?
South. (North → right = East → right = South.)
What formula gives the shortest (straight-line) distance between start and end points in a Direction Sense problem with perpendicular legs?
The Pythagorean theorem: distance = square root of (horizontal displacement squared + vertical displacement squared).
In Direction Sense, what happens to left/right turns when a person walks while facing South instead of North?
Directions reverse relative to North: when facing South, a right turn goes toward West and a left turn toward East.
What is a Syllogism in logical reasoning?
A form of deductive reasoning where a conclusion is drawn from two given premises (statements) that must be assumed true even if they contradict known facts.
What are the four standard categorical statement types (A, E, I, O) used in Syllogism?
A = All (universal affirmative), E = No (universal negative), I = Some (particular affirmative), O = Some...are not (particular negative).
In Syllogism, what is the basic rule about deriving a conclusion from two particular (Some) premises?
Two particular premises yield no valid definite conclusion; at least one premise must be universal to draw a conclusion.
In Syllogism, what is the rule when both premises are negative?
Two negative premises give no valid conclusion.
In Syllogism, what is a "complementary pair" (either-or conclusion)?
When two conclusions individually do not follow but together exhaust all possibilities (e.g., "Some A are B" and "No A are B"), they form an either/or valid pair.
In Syllogism, if a premise says "Some A are B," what immediate (converse) conclusion is always valid?
"Some B are A" — the converse of a particular affirmative (I-type) statement is valid.
In Syllogism, what is the valid conversion of "No A are B"?
"No B are A" — universal negative (E-type) statements convert fully.
In Syllogism, can "All A are B" be converted to "All B are A"?
No. "All A are B" only converts to "Some B are A"; the full reverse is invalid.
What tool is most commonly used to verify Syllogism conclusions visually?
Venn diagrams — overlapping circles representing the sets to test whether a conclusion necessarily holds.
In Venn Diagrams, how are two sets that share some but not all members represented?
As two partially overlapping circles, where the overlap region shows common members (corresponds to "Some A are B").

In Venn Diagrams, how is "All A are B" represented?
Circle A drawn entirely inside circle B.
In Venn Diagrams, how is "No A are B" represented?
Two completely separate (disjoint, non-overlapping) circles.
In a three-set Venn Diagram problem, how many distinct non-overlapping regions can exist?
Seven regions: three for each set alone, three for each pairwise overlap, and one common to all three.
What is the formula for the union of two sets in Venn Diagram problems?
n(A ∪ B) = n(A) + n(B) − n(A ∩ B).
What is the formula for the union of three sets?
n(A∪B∪C) = n(A)+n(B)+n(C) − n(A∩B) − n(B∩C) − n(C∩A) + n(A∩B∩C).
What is Data Sufficiency in reasoning?
A question type where you must decide whether the given statements provide enough information to answer a question — without actually computing the final answer.
In standard Data Sufficiency (two statements), what are the typical answer options?
(a) Statement I alone is sufficient, (b) Statement II alone is sufficient, (c) Both together are needed, (d) Either alone is sufficient, (e) Neither/both together are insufficient.
What is the key principle when solving Data Sufficiency questions?
Evaluate each statement independently first, then together; determine sufficiency only — do not waste time finding the actual numeric answer.
What is Classification ("Odd one out") in reasoning?
A task to identify the one item in a group that does not share the common property (category, pattern, or rule) held by all the others.
What common bases are used to classify items in Classification problems?
Shared category, similar properties, mathematical relationships (squares, primes, multiples), letter patterns, or functional similarity.
In number Classification, which is the odd one: 9, 16, 25, 30?
30 — the others (9, 16, 25) are perfect squares; 30 is not.
What is a Series in reasoning, and what are its two main types?
A sequence following a hidden rule. Two types: number series (arithmetic/geometric/squares etc.) and alphabet/letter series (positional patterns).
In a number Series, what pattern do 2, 6, 12, 20, 30 follow?
Differences increase by 2 each time (4, 6, 8, 10); equivalently n(n+1): 1×2, 2×3, 3×4, 4×5, 5×6.
How do you identify the rule in an alphabet Series?
Convert letters to their position numbers and check the gaps/pattern between consecutive positions (e.g., +2, +3, skip alternate letters).
What is a mixed/alphanumeric Series?
A sequence combining letters, numbers, and sometimes symbols where you track separate patterns for each element type.
What are Puzzles in reasoning, and what is the standard solving approach?
Logical arrangement problems (e.g., scheduling, floors, boxes) solved by tabulating given clues, applying definite clues first, then eliminating possibilities to fix positions.
What is the difference between linear and circular Seating Arrangement?
Linear: people sit in a row facing one direction (left/right fixed). Circular: people sit around a table where facing center reverses left/right compared to facing outward.
In a circular Seating Arrangement where everyone faces the center, where is a person's right neighbor?
When facing the center, a person's right side is the seat in the clockwise direction (toward their right hand), and left is counter-clockwise — opposite to facing outward.
In Seating Arrangement, what does "immediate neighbour" versus "between" mean?
"Immediate neighbour" means seated directly next to (adjacent); "between" means seated somewhere amid two named people, not necessarily adjacent.
In a circular arrangement of n people facing the center, how is the person exactly opposite found?
For an even n, the opposite person sits n/2 seats away in either direction.
What is a Mirror Image in reasoning?
The image formed when an object is placed before a vertical mirror — left and right are interchanged (laterally inverted) while top and bottom stay the same.
Which capital letters look the same in a (vertical) Mirror Image?
A, H, I, M, O, T, U, V, W, X, Y — symmetric about the vertical axis, so they remain unchanged.
What is a Water Image in reasoning?
The image formed when an object is reflected in water — top and bottom are interchanged (vertically inverted) while left and right stay the same.
Which capital letters look the same in a Water Image?
C, D, E, H, I, K, O, X, B — letters symmetric about the horizontal axis remain unchanged when reflected vertically.
In a Mirror Image, how does the order of a sequence of digits or letters change?
The sequence is reversed left-to-right (the last character appears first) in addition to each character being laterally inverted.
What is the key difference between Mirror Image and Water Image?
Mirror image inverts left-right (lateral inversion, vertical axis); water image inverts top-bottom (vertical inversion, horizontal axis).
What does a Paper Folding (and punching) problem test?
Spatial visualization — predicting the pattern of holes/cuts on a paper after it is folded, punched, and then unfolded.
What is the unfolding rule for holes in a Paper Folding problem?
Each fold doubles the holes by mirror symmetry about the fold line; unfold in reverse order, reflecting punched holes across each crease to locate all holes.
If a square paper is folded once and one hole is punched, how many holes appear when unfolded?
Two holes — the punched hole plus its mirror reflection across the single fold line.
In Paper Folding (dot/transparent sheet folding), what does folding along a line produce?
The pattern is reflected across the fold line so the resulting figure is symmetric about that crease, mapping each mark to a mirrored position.
What general skill category do Mirror Images, Water Images, and Paper Folding all belong to?
Non-verbal / spatial visual reasoning, which tests the ability to mentally manipulate and transform figures in space.
