need clarification (Question: 89221.1 )

in case of either or the subject and predicate should be the same. how the answer would be either or ?

Question:
DIRECTIONS: In these questions, relationship between different elements is shown in the statements. The statements are followed by two conclusions.


‘P @ Q’ means ‘P is either greater than or equal to Q’;

‘P © Q’ means ‘P is either smaller than or equal to Q’; 

‘P % Q’ means ‘P is greater than Q’;

‘P * Q’ means ‘P is smaller than Q’; 

‘P $ Q’ means ‘P is neither greater than nor smaller than Q’. 

Statements :

H%J, B©J,B@F


Conclusions: 

I. F$J

II. J%F

Options:
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.
Solution:

Ans:(c) Clearly

(i) P @ Q ⇒ P ≥ Q

(ii) P © Q ⇒ P ≤ Q

(iii) P % Q ⇒ P > Q

(iv) P * Q ⇒ P < Q

(v)P $ Q ⇒ P = Q. 


Statements:

H > J, B ≤ J, B ≥ F 

H > J ≥ B ≥ F


Conclusions:

I. F = J                (may be true)

II. J >F                (may be true)

Either Conclusion I or II is true.

Either or condition:


1)Subject and predicate of the two conclusions should be same (may not be in the same order)


2)Individually both conclusions should be false


3)Both conclusions should cover maximum solutions according to the given statement.



Clearly
(i) P @ Q ⇒ P ≥ Q
(ii) P © Q ⇒ P ≤ Q
(iii) P % Q ⇒ P > Q
(iv) P * Q ⇒ P < Q
(v)P $ Q ⇒ P = Q.

Statements:
H > J, B ≤ J, B ≥ F
H > J ≥ B ≥ F

Conclusions:
I. F = J (may be true)
II. J >F (may be true)

Either Conclusion I or II is true.
