RRB Group D General Intelligence and Reasoning Flashcards

24 sample cards from the General Intelligence and Reasoning deck

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

1. What is the 'Direction Sense' reasoning topic?

   Problems requiring you to track movement and turns (left/right, clockwise) across the four cardinal and four ordinal directions to find final position, distance, or direction.

2. Name the four cardinal and four ordinal (intercardinal) directions.

   Cardinal: North, East, South, West. Ordinal: North-East, South-East, South-West, North-West.

3. If you face North and turn 90° to your right, which direction do you face? And then another 90° right?

   First turn faces East; the second 90° right turn faces South.

4. In Direction Sense, which formula gives the straight-line (shortest) distance after moving along two perpendicular legs of lengths a and b?

   Pythagoras' theorem: shortest distance = √(a² + b²).

5. A man walks 3 km North then 4 km East. How far is he from the start (straight line)?

   5 km. By Pythagoras: √(3² + 4²) = √25 = 5.

6. At sunrise (morning), if your shadow falls to your left, which direction are you facing?

   North. The sun rises in the East, so shadows point West; if West (shadow) is to your left, you face North.

7. What does 'Ranking and Ordering' reasoning involve?

   Arranging people/objects in a sequence (by rank, height, age, etc.) from clues, and answering position questions from the top, bottom, left, or right.

8. In a row of n people, if a person is r-th from one end, what is their position from the other end?

   Position from other end = (n − r) + 1, i.e. n − r + 1.

9. In a row of 40 students, A is 12th from the left. What is A's position from the right?

   29th. Position from right = 40 − 12 + 1 = 29.

10. If in a class a student ranks 7th from the top and 18th from the bottom, how many students are in the class?

    24 students. Total = 7 + 18 − 1 = 24 (subtract 1 because the student is counted twice).

11. What is the 'Seating Arrangement' reasoning topic?

    Problems where you place people in a seating layout (linear row, circular table, or facing each other) according to constraints, then answer who sits where or who is adjacent.

12. In a circular seating arrangement with people facing the centre, are left/right directions same or opposite to a person facing outward?

    They are opposite. For someone facing the centre, their left is the observer's right; for someone facing outward, directions reverse. Always orient based on each person's facing.

13. What is a 'Syllogism' in logical reasoning?

    A form of deductive reasoning with two premises and a conclusion, where you must judge whether the conclusion necessarily follows from the given statements (often using Venn diagrams).

14. In syllogisms, what does the statement 'All A are B' allow and not allow you to conclude about B and A?

    It allows 'Some B are A' (conversion), but NOT 'All B are A'. Some B may not be A.

15. In syllogisms, what can you conclude from 'No A are B'?

    You can conclude 'No B are A' as well (the universal negative converts). A and B have no overlap.

16. Syllogism: All cats are animals. All animals are living things. What conclusion follows?

    All cats are living things (and Some living things are cats). The relation chains through the middle term 'animals'.

17. In syllogism rules, what does 'Some A are B' tell you about the converse?

    'Some A are B' implies 'Some B are A'. Particular affirmative statements convert validly.

18. What is the 'Statement and Argument' reasoning topic?

    You are given a statement (usually a proposal) and arguments for/against it; you must judge which arguments are 'strong' (relevant, logical, substantial) versus 'weak' (trivial, irrelevant, ambiguous).

19. What makes an argument 'strong' versus 'weak' in Statement and Argument questions?

    Strong arguments are directly related to the statement, logically sound, and address real/important aspects. Weak arguments are superficial, irrelevant, based on assumptions, or merely restate the statement.

20. What is the 'Statement and Conclusion' reasoning topic?

    You are given a statement (assumed true) and one or more conclusions; you must decide which conclusion(s) logically and definitely follow from the statement alone.

21. Key rule for Statement and Conclusion: can a valid conclusion rely on outside knowledge or assumptions?

    No. A conclusion must follow strictly and necessarily from the information in the statement itself, without adding external assumptions.

22. How does 'Statement and Conclusion' differ from 'Statement and Argument'?

    In Statement and Conclusion you judge what logically follows (a deduction); in Statement and Argument you evaluate the strength/relevance of supporting or opposing reasons for a proposal.

23. What does the 'Decision Making' reasoning topic test?

    Applying a given set of rules/conditions/eligibility criteria to specific cases or candidates to decide the correct action or outcome (e.g. who qualifies, what should be done).

24. What is the recommended approach to a Decision Making question with multiple eligibility conditions?

    Read all conditions and exceptions carefully, then check each candidate/case against every condition one by one; classify based on which conditions are met, partially met, or fail (referred to higher authority).
