Answers with solutions


P % Q means P is not smaller than Q —————–  [ P≥ Q ]
P © Q means P is neither smaller than nor equal to Q —  [ P > Q]
P x Q means P is neither greater than nor equal to Q ——— [ P < Q ]
P ∂ Q means P is not greater than Q ———- [  P ≤  Q  ]
P @ Q means P is neither greater than nor smaller than Q——- [ P=Q ]

 1. (D) Statement – R ∂ K ; K x M ; M @ J
                    R ≤ K < M = J
Conclusions -:
I.     J ©  K ——-    [  J > K ]
II.   M © R —-    [  M > R ]
III.  R  X J  ——    [  R < J  ]
Clearly All the conclusions are true

 2 -(C) Statements –  Z @ M ; M © K ; K X F
                                 Z = M  > K  < F
Conclusions – :
I.     F © Z ———-  [ F > Z ] cannot be said.
II.   K X Z ———   [ K < Z ] Surely it is
III.  F © M ——–    [ F > M ] cannot be said
So Only II is correct.

3- (E)Statements – V % H ; H @ F ; F ∂ E
                               V ≥ H = F ≤ E
Conclusions :-
I.     F @ V —-    [ F=V ] not sure may nor may not be
II.   F X V ———   [ F < V ] Not sure may or may not be
III.  E % H ——- [ E ≥ H ] Surely.
But here F= H & H ≤ V so indirectly F≤V so either F= V or F < V but not both at a time, but atleast one has to hold. So either I or II should be there and III is always right. So answer is either I or II  & III are correct.

 4 -(A) Statements – W ©  T ; T ∂ N ; N % D
       Means – W > T
                  N ≥ T
                  N ≥ D  
Conclusions :-
I.     D X T  —–  [ D < T ] cannot be said. No idea of relation between them
II.   W © N — [ W > N ] cannot be said
III.  D @ T — [ D = T ]  cannot be said.
So here None is true.

A $ B means A not a lessthan B Therefore, A = B
A # B means A not a greater than B Therefore, A = B
A @ B means A not a lessthan B and A ? B Therefore, A = B
A © B means A not a lessthan B and A !> B Therefore, A = B
A % B means A not a greater than B and A ? B Therefore, A < B

5.(B)  H % J  = H < J
    J © N  = J = N
   N @ R  = N > R
   Therefore, H < J = N > R

Conclusions:
I. R % J  = R < J ( True )
II. H @ J  =H > J ( Not true)
III. N @ J   =N > H (True)

 6.(E)
M % J  = M  > J
J $ T  = J = T
T © N  =T = N
Therefore, M > J = T = N

Conclusions:
I. N # J  = N = J ( true )
II. T % M  = T < M ( true)
III. M @ N  =M > N ( true)

7.(C)
D © K -> D = K
K # F -> K = F
F @ P -> F > P
Therefore, D = K = F > P

Conclusions:
I. P @ D -> P > D ( Not true )
II. K # P -> K = P ( Not true )
III.F $ D -> F = D ( True )

8. (D)
K # N -> K = N
N $ T -> N = T
T % J -> T > J
Therefore, K = N = T > J
Conclusions:
I. J @ N -> J > N ( Not true )
II. K @ T -> K > T ( Not true )
III.T @ K -> T > K ( Not true )

9. (C)
Statements D * Q -> D = Q
D @ L -> Q > L
L $ B -> L = B
B # G -> B < G
Therefore, D = Q > L = B < G
Conclusions:
I. D @ B -> D > B ( True )
II. B * D -> B = D ( Not true)
III.G @ L -> G < L (Not true)

10.(E)
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)

11.(A)
Statements: P # M -> p < M
M % R -> M = R
R * T -> R = T
T # L -> T < L
Therefore, P < M = R = T < L
Conclusions:
I. P # R -> P < R ( true )
II. P * R -> P = R ( Not true)
III.  M % L -> M = L (Not true)

12.(B)
Statements: F @ H -> F > H
M % H -> M = H
M $ R -> M = R
G * M -> G = M
Therefore, G > H = M = G = R
Conclusions:
I. F $ R -> F = R (Not true )
II. F @ R -> F > R ( true)
III.H $ G -> H = G ( true)
