conclusion (Question: 111394.1 )

option should be I nd Either III or IV

Question:

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


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

‘P δ 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 the given statements to be true, find which of the four Conclusions I, II, III and IV given below them is/are definitely true and give your answer.

Statements:

H δ J, J # N, N @ R, R δ W


Conclusions:

I. W % N

II. W % H

III. R # J

IV. R δ J
Options:
A) Only I is true
B) Only II is true
C) Only III is true
D) Only IV is true
E) Either III or IV is true
Solution:

Ans : (e)

P % Q ⟹P < Q

P δ Q ⟹P > Q

P @ Q ⟹P ≤ Q

P * Q ⟹P ≥ Q

P # Q ⟹P = Q

Statements :

H δ J ⟹H > J

J # N ⟹J = N

N @ R ⟹N ≤ R

R δ W ⟹ R > W

So, H > J = N ≤ R > W

Conclusions:

I. W % N ⟹W < N…… (false)

II. W % H ⟹W < H ……. (false)

III. R # J ⟹R = J……… (may be true)

IV. R δ J ⟹R > J ……… (may be true)

Only either III or IV is true.

Hi Sneha, first conclusion can not be true because we do not have any between them..

Option(e) is correct..

P % Q ⟹P < Q
P δ Q ⟹P > Q
P @ Q ⟹P ≤ Q
P * Q ⟹P ≥ Q
P # Q ⟹P = Q
Statements :
H δ J ⟹H > J
J # N ⟹J = N
N @ R ⟹N ≤ R
R δ W ⟹ R > W
So, H > J = N ≤ R > W
Conclusions:
I. W % N ⟹W < N…… (false)
II. W % H ⟹W < H ……. (false)
III. R # J ⟹R = J……… (may be true)
IV. R δ J ⟹R > J ……… (may be true)
Only either III or IV is true.
