Directions (6 – 10): In these questions, relationship between different elements is shown in the statements. The statements are followed by conclusions. Give answer.

  1. Statements: D > H ≥ N; S > I ≤ H
    Conclusions:
    I. N ≤ S
    II. I < D
    A) if only Conclusion I is true
    B) if only Conclusion II is true
    C) if either Conclusion I or II is true
    D) if neither Conclusion I nor II is true
    E) if both Conclusions I and II are true
    Answer
    B) if only Conclusion II is true
    Explanation:

    S > I ≤ H ≥ N gives no relationship between N and S.
    I ≤ H < D, so I < D
  2. Statements: P ≤ O < I; P > Y > W
    Conclusions:
    I. Y ≤ I
    II. O > W
    A) if only Conclusion I is true
    B) if only Conclusion II is true
    C) if either Conclusion I or II is true
    D) if neither Conclusion I nor II is true
    E) if both Conclusions I and II are true
    Answer
    B) if only Conclusion II is true
    Explanation:

    Y < P ≤ O < I, so Y < I not Y ≤ I
    W < Y < P ≤ O, so W < O
  3. Statements : A ≥ B > C ≥ F; Z < C ≤ D < E
    Conclusions:
    I. A > Z
    II. F < E
    A) if only Conclusion I is true
    B) if only Conclusion II is true
    C) if either Conclusion I or II is true
    D) if neither Conclusion I nor II is true
    E) if both Conclusions I and II are true
    Answer
    E) if both Conclusions I and II are true
    Explanation:

    A ≥ B > C > Z, so A > Z
    E > D ≥ C ≥ F, so E > F
  4. Statements : A ≥ B ≥ C, C < D > F
    Conclusions:
    I. F > B
    II. A > D
    A) if only Conclusion I is true
    B) if only Conclusion II is true
    C) if either Conclusion I or II is true
    D) if neither Conclusion I nor II is true
    E) if both Conclusions I and II are true
    Answer
    D) if neither Conclusion I nor II is true
    Explanation:

    A ≥ B ≥ C < D > F gives no relationship between B and F and also between A and D.
  5. Statements : X > Y ≥ Z, Q = Y, P > X
    Conclusions:
    I. Z < P II. P > Q
    A) if only Conclusion I is true
    B) if only Conclusion II is true
    C) if either Conclusion I or II is true
    D) if neither Conclusion I nor II is true
    E) if both Conclusions I and II are true
    Answer
    E) if both Conclusions I and II are true
    Explanation:

    P > X > Y ≥ Z gives P > Z
    P > X > Y = Q, so P > Q
