NABARD Grade A Reasoning Ability Flashcards

24 sample cards from the Reasoning Ability deck

Sampled from the end of the deck, so these are different cards from the ones shown on the syllabus page.

1. In ordering and ranking, if a person is 'Xth from the top' and 'Yth from the bottom' in a row of N people, what is the relation between X, Y and N?

   N = X + Y - 1 (total = rank from top + rank from bottom minus 1, since the person is counted twice).

2. In a row of N people, if a person is Xth from the left, what is their position from the right?

   Position from the right = N - X + 1.

3. In ranking, how many people are there between two persons ranked Pth and Qth from the same end (P less than Q)?

   Number of people between them = Q - P - 1.

4. In a distribution/comparison ranking (e.g., A is taller than B, B than C), how do you build the order?

   Convert each comparison into an inequality chain (A > B > C) and arrange all elements into a single ascending or descending sequence.

5. In Input-Output reasoning, what does a 'machine' do at each step?

   An input-output machine rearranges words/numbers following a fixed logical pattern (e.g., shifting, sorting, alternating) at each successive step until a final arrangement is reached.

6. In Input-Output problems, what are the common patterns/operations used in each step?

   Common operations: arranging words alphabetically, numbers in ascending/descending order, moving smallest/largest to one end alternately, or shifting one element per step from either end.

7. In Input-Output, how do you determine the number of steps needed to complete the arrangement?

   Steps usually equal the number of elements that must be moved into their final positions; the last step is when no further rearrangement is possible.

8. In Data Sufficiency, what does it mean when 'Statement I alone is sufficient but Statement II alone is not'?

   It means the question can be answered definitively using only Statement I, while Statement II alone does not give enough information to answer.

9. In Data Sufficiency, what is the standard meaning of the option 'Both statements together are sufficient, but neither alone is sufficient'?

   Neither statement individually answers the question, but combining the information from both statements gives a definite, unique answer.

10. What is the key principle when solving Data Sufficiency questions (do you need to find the actual answer)?

    You only need to determine whether the data is SUFFICIENT to find a unique answer, not to compute the actual final value.

11. In Data Sufficiency, what does the option 'Data in both statements is not sufficient' indicate?

    Even using both statements together, the information is inadequate to arrive at a definite, unique answer, so additional data is required.

12. In logical deduction (Venn diagrams), how do you represent 'All A are B'?

    Draw circle A entirely inside circle B, showing every element of A is also in B (A is a subset of B).

13. In Venn diagrams, how do you represent 'No A is B' and 'Some A are B'?

    'No A is B': two separate non-overlapping circles. 'Some A are B': two partially overlapping circles with a common shaded region.

14. In logical deduction, what is the difference between deductive and inductive reasoning?

    Deductive reasoning moves from general premises to a specific, certain conclusion; inductive reasoning moves from specific observations to a general, probable conclusion.

15. What is the standard logic of a number series like 2, 6, 12, 20, 30 (find the pattern)?

    The differences are 4, 6, 8, 10 (increasing by 2), so each term is n(n+1): 1x2, 2x3, 3x4, 4x5, 5x6 = 2, 6, 12, 20, 30.

16. What is the rule of a Fibonacci-type series (e.g., 1, 1, 2, 3, 5, 8)?

    Each term is the sum of the two preceding terms (1+1=2, 1+2=3, 2+3=5, 3+5=8).

17. In analogy, what is the relationship type in 'Doctor : Hospital :: Teacher : ?'?

    It is a person-to-workplace analogy; the answer is School (a teacher works in a school as a doctor works in a hospital).

18. In a number analogy like '6 : 36 :: 8 : ?', what is the relationship and the answer?

    The relationship is square (6^2 = 36), so 8^2 = 64.

19. What is the common pattern in an alternating/double number series (e.g., 1, 5, 2, 10, 3, 15)?

    Two interleaved series exist: odd positions 1, 2, 3 (increasing by 1) and even positions 5, 10, 15 (increasing by 5); next term is 4.

20. In Order and Sequence problems, how do you arrange events given relative time/position clues?

    Convert each clue into a 'before/after' relationship, then chain them into a single timeline or sequence from earliest to latest (or first to last).

21. In alphabet sequence questions, what is the position of the middle letter of the English alphabet?

    The English alphabet has 26 letters, so there is no single middle letter; the two central letters are the 13th (M) and 14th (N).

22. What is the formula to find the nth letter from the end of the alphabet?

    The nth letter from the end corresponds to the (27 - n)th letter from the beginning (e.g., 5th from end = 22nd letter = V).

23. In odd-one-out (classification) questions, what is the solving approach?

    Identify the common property shared by most elements (category, number property, shape, function); the element that does not share that property is the odd one out.

24. What is the key general strategy for the Miscellaneous Reasoning section (mixed verbal/non-verbal items)?

    Quickly identify the question type (series, analogy, classification, coding, etc.), apply the relevant rule, eliminate wrong options, and verify the answer against all given conditions before finalizing.
