there is no relation between D & N

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


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

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

‘P @ Q’ means  ‘P is not greater than Q’.

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

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


Now in each of the following questions assuming me given statements to be true, find which of the three conclusions I, II and III given below them is/are definitely true and give your answer accordingly.

Statements:

D*K, K%N, N@F


Conclusions:

I. D*N 

II. F*K

III.D@N

Options:
A) Only II is true
B) Only either I or III and II are true
C) Only either I or III is true
D) Only I and II are true
E) None of these
Solution:
Ans : (b)

Given that,

P % Q ⟹ P < Q

P * Q  ⟹ P > Q 

P @ Q ⟹ P ≤ Q 

P # Q  ⟹ P ≥ Q 

P © Q ⟹ P = Q  


Statement:

D  * K  ⇒ D > K 

K % N ⇒  K < N 

N @ F ⇒ N ≤ F

Hence,

D > K < N ≤ F

yes we know that there is no relation between D and N given in the statement....But you must know the thing that only three signs occur in inequalities viz. >/=/<...so anyone of them must will occur to correlate D and N....so, Conclusion I and III indicating all the three signs. so either I or III is correct....
