Reasoning Ability flashcards for RBI Grade B Officer

22 of 50 cards from the Reasoning Ability deck — real questions with worked answers.

1. In syllogism logic, what does the statement "All A are B" allow you to conclude about the relationship between A and B?

   Every member of A is included in B, so "Some B are A" and "Some A are B" follow, but the reverse "All B are A" is NOT guaranteed.

2. What is the valid conclusion from "No A are B" regarding converse statements?

   "No A are B" implies "No B are A" (the negative universal converts fully). Also "Some A are not B" and "Some B are not A" hold.

3. From two particular premises (e.g., "Some A are B" and "Some B are C"), what definite conclusion can be drawn in syllogisms?

   No definite conclusion can be drawn from two particular premises; at least one premise must be universal for a valid conclusion.

4. What is the "possibility" rule in syllogisms when a definite conclusion is false?

   If a conclusion does not definitely follow, check if it is possible (can be true in at least one valid diagram). "Possibility" conclusions are accepted when the case can be drawn without contradicting the premises.

5. In syllogisms, when does "Some A are not B" become a valid conclusion?

   It follows when at least one premise is negative and the structure supports it, e.g., from "All A are B" you can NOT get it, but from "No B are C" + "Some A are C" you can derive "Some A are not B."

6. What is the key principle of the complementary pair (either-or) in syllogisms?

   When two given conclusions individually do not follow but together exhaust all possibilities (same subject and predicate, one positive one negative, e.g., "Some A are B" / "Some A are not B"), the "Either-Or" case is valid.

7. In Statement and Assumptions questions, what is an "assumption"?

   An assumption is something taken for granted or implied (not stated) that must be true for the statement to make sense or be acted upon.

8. In Statement and Conclusions reasoning, what test must a conclusion pass to be valid?

   A conclusion must follow logically and necessarily from the information given in the statement alone, without external knowledge or assumptions.

9. In a "Statement and Courses of Action" question, when is a course of action considered to follow?

   When it logically addresses the problem in the statement and is a practical, reasonable step that would help solve or improve the situation.

10. In "Statement and Arguments," what distinguishes a strong argument from a weak one?

    A strong argument is directly related to the question, important, and based on reason/facts; a weak argument is trivial, ambiguous, or based on a minor/individual case.

11. What is an "Analogy" in reasoning, and what is the solving approach?

    An analogy expresses a similar relationship between two pairs (A:B :: C:D). Identify the exact relationship in the first pair (function, type, opposite, etc.) and apply the same to find the missing term.

12. In Classification (Odd-One-Out), what is the task?

    Identify the one element that does NOT share the common property/relationship that the other elements have; the odd one breaks the pattern.

13. Give the common analogy relationship types tested in reasoning.

    Synonym, antonym, cause-effect, worker-tool, part-whole, function, category/class, degree of intensity, symbol/sign, and quantity relationships.

14. In number analogy, if 5:30 then 8:? following the pattern n:(n*(n+1)), what is the answer?

    72, because 5*6=30 and 8*9=72.

15. In a linear arrangement "facing North," how do left and right of a person relate to your viewing direction?

    When people face North, a person's left is to YOUR right and a person's right is to YOUR left (mirror), so left of the person = west, right = east.

16. In a single-row linear arrangement where all face South, how is left/right oriented?

    Facing South, the person's left is to your left and right is to your right; left = east, right = west.

17. In a circular arrangement where all members face the CENTER, how do left and right work?

    Facing the center, a person's left hand points clockwise and right hand points anticlockwise (i.e., immediate left = next clockwise neighbor).

18. In a circular arrangement where all members face OUTSIDE (away from center), how do left and right work?

    Facing outward, a person's left points anticlockwise and right points clockwise — the reverse of the facing-center case.

19. In circular seating, if some face center and some face outside, what determines two people facing each other?

    Two adjacent people face each other only if one faces the center and the other faces outward toward them; same-direction neighbors face the same way.

20. What is the standard approach to solve a floor-based puzzle?

    Number floors bottom (1, lowest) to top (highest), translate clues like "above/below," "immediately above," and gaps into positions, and fix definite clues first before testing possibilities.

21. In scheduling/day-month puzzles, what is the first step after reading clues?

    Set up the fixed sequence (days of week or months in order), place absolute clues first, then relative clues (before/after, gap of N), and iterate possibilities.

22. In a box/stack puzzle, what does "two boxes between P and Q" mean for their positions?

    There is a gap of exactly two boxes; if P is at position 1, Q is at position 4 (or vice versa) — positions differ by 3.
