    J > M ...(i) M < K ...(ii) K ≥ D ...(iii)
    From (i) and (ii) J and K can't be compared and consequently J and D can't be compared. Hence neither III nor I follows. From (ii) and (iii) D and M can't be compared
    Hence II does not follow.

    Correct Option: A

    J > M ...(i) M < K ...(ii) K ≥ D ...(iii)
    From (i) and (ii) J and K can't be compared and consequently J and D can't be compared. Hence neither III nor I follows. From (ii) and (iii) D and M can't be compared
    Hence II does not follow.


  1. Statements:
    R @ K, K S F, F * N
    Conclusions:
    I. N © R, II. F @ R, III. F © R
    1. Only I is true
    2. Only either II or III is true
    3. Only I and either II or III are true
    4. Only III is true
    5. None of these

    R = K ...(i) K ≤ F ... (ii) F < K ...(iii)
    Combining these we get R = K ≤ F < N.
    Hence K > R and I follow.
    Also F ≥ R. Hence either II (F = R) or III (F = R) and follows.

    Correct Option: C

    R = K ...(i) K ≤ F ... (ii) F < K ...(iii)
    Combining these we get R = K ≤ F < N.
    Hence K > R and I follow.
    Also F ≥ R. Hence either II (F = R) or III (F = R) and follows.



  1. Statements:
    R S D, D @ N, N © F
    Conclusions:
    I. F * D II. F * R III. N % R
    1. Only I and II are true
    2. Only I and III are true
    3. Only II and III are true
    4. All are true
    5. None of these

    R ≤ D ...(i) D = N ...(ii) N > F ...(iii)
    From (ii) and (iii) D = N > F or F < D ...(iv)
    Hence I follow
    From (i) and (iv) F and R can't be compared Hence II does not follow.

    Correct Option: B

    R ≤ D ...(i) D = N ...(ii) N > F ...(iii)
    From (ii) and (iii) D = N > F or F < D ...(iv)
    Hence I follow
    From (i) and (iv) F and R can't be compared Hence II does not follow.


  1. Statements:
    H * T, T S B, B © R
    Conclusions:
    I. R © H II. B © H III. T % R
    1. Only i is true
    2. Only I and II are true
    3. Only I and III are true
    4. Only II and III are true
    5. None of these

    H < T ...(i) T ≤ B ...(ii) B > R ...(iii)
    From (i) and (ii) we get H < T ≤ B or B > H.
    Hence III does not follow.

    Correct Option: E

    H < T ...(i) T ≤ B ...(ii) B > R ...(iii)
    From (i) and (ii) we get H < T ≤ B or B > H.
    Hence III does not follow.

    M < T ...(i) T ≥ J ...(ii) J > K ...(iii)
    From (ii) and (iii) T ≥ J > K or K < T.
    Hence I follows.
    From (i) and (ii) M and J can't be compared. Hence II does not follows.Nor can III follows.

    Correct Option: D

    M < T ...(i) T ≥ J ...(ii) J > K ...(iii)
    From (ii) and (iii) T ≥ J > K or K < T.
    Hence I follows.
    From (i) and (ii) M and J can't be compared. Hence II does not follows.Nor can III follows.
