Reasoning and Analytical Ability flashcards for RBI Grade B

19 of 51 cards from the Reasoning and Analytical Ability deck — real questions with worked answers.

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

   Every member of A is contained in B (A is a subset of B), but not all B are necessarily A. The valid converse is the particular "Some B are A."

2. What is the rule for drawing a definite conclusion from two particular statements (both starting with "Some") in syllogism?

   No definite conclusion can be drawn from two particular premises. At least one premise must be universal (All/No) to derive a valid conclusion.

3. In syllogism, what is a "complementary pair" (either-or conclusion)?

   When two conclusions individually fail but together exhaust all possibilities (one is "Some A are B" and the other "No A are B" / "Some A are not B" on the same terms), the answer is "either I or II follows."

4. From "No A are B," what immediate conversions are valid in syllogism?

   "No B are A" (full conversion holds for No-statements) and "Some A are not B" / "Some B are not A."

5. In syllogism, can a universal negative conclusion ("No") follow from two affirmative premises?

   No. A negative conclusion requires at least one negative premise. Two affirmative premises can never yield a negative conclusion.

6. In letter-shift coding, if in a code each letter is replaced by the letter 2 places ahead, how is "CAT" coded?

   "ECV" — C→E, A→C, T→V (each shifted forward by 2 positions in the alphabet).

7. What is the standard alphabet position value of the letters A, J, S, and Z?

   A = 1, J = 10, S = 19, Z = 26. (EJOTY mnemonic: E=5, J=10, O=15, T=20, Y=25.)

8. In substitution-type coding-decoding, what is the basic technique to crack the code?

   Compare the given coded words letter-by-letter to find which code-symbol consistently maps to which letter across multiple statements, then decode the target word.

9. What is the reverse-alphabet (opposite letter) value, and how do you find a letter's opposite?

   Opposite of a letter = (27 minus its position). E.g., A(1)↔Z(26), B(2)↔Y(25), M(13)↔N(14). Position + opposite position = 27.

10. In a blood relations problem, what does "the only daughter of my mother's brother" identify the person as?

    The cousin (specifically the female cousin) — mother's brother is the maternal uncle, so his daughter is the speaker's cousin.

11. In direction sense, starting facing North and turning clockwise, what are the four cardinal directions in order?

    North → East → South → West (clockwise). Anticlockwise: North → West → South → East.

12. In direction sense, how do you find the shortest (straight-line) distance between start and end points after perpendicular movements?

    Use the Pythagorean theorem: shortest distance = sqrt((net horizontal displacement)^2 + (net vertical displacement)^2).

13. In blood relations, what relation is "my father's only son" to me (when said by a male)?

    Myself. The father's only son is the speaker himself (if the speaker is male).

14. In direction sense, if you face South and take a left turn, which direction do you now face?

    East. (Facing South, left turn = East; right turn = West.)

15. In blood relations coding (e.g., A + B means A is father of B), what does each operator typically need to be defined as before solving?

    Each symbol (+, -, x, ÷) is assigned a specific relationship and gender; you must first list these definitions, then build the family chain step by step.

16. In inequalities, what conclusion follows from the chain A > B > C?

    A > C (and A > B, B > C). The relationship is transitive for the same direction of strict inequality.

17. In coded inequalities, if A ≥ B and B > C, can you conclude A > C?

    Yes. "At least" combined with "greater than" yields strictly greater than: A ≥ B > C implies A > C.

18. In inequalities, when does the "either-or" case arise between two conclusions?

    When the relation between two variables is undefined by the chain (e.g., from A ≥ B and A > C you cannot order B and C), and the two conclusions B ≥ C and B < C / B > C together cover all possibilities on the same pair.

19. In inequalities, what does A ≤ B ≤ C combined with C = D let you conclude about A and D?

    A ≤ D (A ≤ B ≤ C = D), so A is less than or equal to D.
