Question:

DIRECTIONS: In the following questions, the symbols #, $, @, % and © are used with the following meaning as illustrated below:


‘P # Q’ means ‘P is not smaller than Q’.

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

‘P @ Q’ means P is neither greater than nor equal to Q’.

‘P % Q’ means ‘P is not greater than Q’

‘P © Q’ means ‘P is neither smaller than nor equal to Q’.


Now 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? 

Statements:

F # G, N $ G, N © T


Conclusions:

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: (b) (i) P # Q means P < Q.

Therefore P > Q or P = Q  Thus P ≥ Q

(ii) P $ Q means P< Q and P > Q. Therefore P = Q

(iii) P @ Q means P > Q and P ≠ Q. Therefore P < G

(iv) P % Q means P > Q. Therefore P < Q or P = Q. Thus P ≤ Q

(v) P © Q means P < Q and P ≠ Q. Therefore P > Q. Thus,

P ≠ Q ⇒ ≥

P $ Q ⇒ =

P @ Q ⇒ <

P % Q ⇒ ≤ 

P © Q ⇒ >

Statements

                F # G ⇒ F ≥ G

N $ G ⇒ N = G

N © T ⇒ N > T

Therefore F ≥ G = N > T

Conclusions

I. T © F  ⇒ T > G             (False)

II. N % F  ⇒ N ≤ F           (True)
