answer is wrong (Question: 119463.0 )

wrong answer only 2 follows

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

why???????..........do you have any fourth symbol of inequality two correlate two elements???.....No, we have only three signs viz. >, = and <...one of them had to be between two elements.....so if we do not have any relation between two elements and all those three signs appear in the conclusions then it must make contradiction....Thats why either I or III and III are true....
