Statements:
Z @ Y, Y # K, K % M, M @ T
Conclusions:
I. Z @ M
II. Y @ T
III. Z # K

A.) I only
B.) II and III only
C.) Either I or II only
D.) None is true

Statements: Z @ Y -> Z > Y
Y # K -> Y < K
K % M -> K = M
M @ T -> M > T
Therefore, Z > Y < K = M > T
Conclusions:
I. Z @ Y -> Z > Y (Not true )
II. Y @ T -> Y > T ( Not true)
III.Z # K -> Z < K (Not true)

• Instructions : (5 - 7) -
In the following questions, the Symbols @,

4.

Statements:
C & D, D \$ E, E © F
Conclusions:
I .F @ C
II. E @ C

A.) If only conclusion I is true
B.) If only conclusion II is true
C.) If either conclusion I or conclusion II is true
D.) If both conclusions I and II are true.

‘A \$ B’ -> A !> B, therefore A = B.
‘A @ B’ -> A B.
‘A & B’ -> A !> B and A ‘A © B’ -> A !> B and A ‘A % B’ -> A C & D -> C < D
D \$ E -> D = E
E © F -> E = F
Therefore C < D = E = F
Conclusions:
1. F @ C -> F > C ( True )
2. E @ C -> E > C ( True )

• Instructions (1-2) :-
