Mathematical operation and symbol notation


Direction: In these question, relationship between different element is shown in the statements. These statements are followed by two conclusions.

  1. Statements:
    L ≤ M < N > O ≥ P
    Conclusions:
    I. O < M II. P ≤ N
    1. If only conclusion I follows
    2. If only conclusion II follows
    3. If either conclusion I or II follows
    4. If neither conclusion I nor II follows
    5. If both conclusion I and II follow.

    If neither conclusion I nor II follows

    Correct Option: D

    If neither conclusion I nor II follows


Direction: In these following question, the symbols @, S, #, * and % are used with the different meaning as follow:
'A @ B' means 'A is smallest than B'.
'A S B' means 'A is greater than B'.
'A # B' means 'A is either smallest than or equal to B.
'A * B' means 'A is either greater than or equal to B.
'A % B' means 'A is either smallest than nor greater equal to B'.
In each of the following questions assuming the given statements to be true, find which of the two conclusions I and II given below them is/are definitely true.

  1. Statements:
    K * D, D S L, L @ J
    Conclusions:
    I. K S L II. K # J
    1. if only conclusion I is true
    2. if only conclusion II is true
    3. if either conclusion I or conclusion II is true
    4. if neither conclusion I nor conclusion II is true
    5. if both conclusion I and II are true

    K ≥ D ...(i) D > L ...(ii) L < J ...(iii)
    From (i) and (ii) K ≥ D > L or K > L ....(iv)
    Hence I follows
    However, From (iii) and (iv) J and H can't be compared . Hence II does not follow.

    Correct Option: A

    K ≥ D ...(i) D > L ...(ii) L < J ...(iii)
    From (i) and (ii) K ≥ D > L or K > L ....(iv)
    Hence I follows
    However, From (iii) and (iv) J and H can't be compared . Hence II does not follow.



  1. Statements:
    T # J, J * I, I @ W
    Conclusions:
    I. J @ W II. T % I
    1. if only conclusion I is true
    2. if only conclusion II is true
    3. if either conclusion I or conclusion II is true
    4. if neither conclusion I nor conclusion II is true
    5. if both conclusion I and II are true

    T ≤ J ...(i) J ≥ I ...(ii) I < W ...(iii)
    From (ii) and (iii) J and W can't be compared. Hence I does not follow
    From (i) and (ii) T and I can't be compared. Hence II does not follow

    Correct Option: D

    T ≤ J ...(i) J ≥ I ...(ii) I < W ...(iii)
    From (ii) and (iii) J and W can't be compared. Hence I does not follow
    From (i) and (ii) T and I can't be compared. Hence II does not follow


  1. Statements:
    E @ U, U %R, R S F
    Conclusions:
    I. E S F II. E * F
    1. if only conclusion I is true
    2. if only conclusion II is true
    3. if either conclusion I or conclusion II is true
    4. if neither conclusion I nor conclusion II is true
    5. if both conclusion I and II are true

    E < U ...(i) U = R ...(ii) R > F ...(iii)
    From (i) and (ii) E < R ...(iv)
    Now, From (iii) and (iv) E and F can't be compared
    Hence neither I nor II follows.

    Correct Option: D

    E < U ...(i) U = R ...(ii) R > F ...(iii)
    From (i) and (ii) E < R ...(iv)
    Now, From (iii) and (iv) E and F can't be compared
    Hence neither I nor II follows.



  1. Statements:
    P @ W, W * D, D S J
    Conclusions:
    I. J @ P II. J @ W
    1. if only conclusion I is true
    2. if only conclusion II is true
    3. if either conclusion I or conclusion II is true
    4. if neither conclusion I nor conclusion II is true
    5. if both conclusion I and II are true

    P < W ...(i) W ≥ D ...(ii) D > J ...(iii)
    From (ii) and (iii) W ≥ D > J or J < W ...(iv)
    Hence II follows. However, from (i) and (iv) we can conclude that J and P can't be compared. Hence I does not follow.

    Correct Option: B

    P < W ...(i) W ≥ D ...(ii) D > J ...(iii)
    From (ii) and (iii) W ≥ D > J or J < W ...(iv)
    Hence II follows. However, from (i) and (iv) we can conclude that J and P can't be compared. Hence I does not follow.
