Correct Answer:
Explanation:
F < E < J ? H > Z H ? Y and Z < H
Correct Answer: E > C
Explanation:
E > C
Correct Answer: Only I is true
Explanation:
M < T ...(i) T ? J ...(ii) J > K ...(iii)
From (ii) and (iii) T ? J > K or K < T.
Hence I follows.
From (i) and (ii) M and J can't be compared. Hence II does not follows.Nor can III follows.
Correct Answer:
Explanation:
H < T ...(i) T ? B ...(ii) B > R ...(iii)
From (i) and (ii) we get H < T ? B or B > H.
Hence III does not follow.
Correct Answer: Only I and III are true
Explanation:
R ? D ...(i) D = N ...(ii) N > F ...(iii)
From (ii) and (iii) D = N > F or F < D ...(iv)
Hence I follow
From (i) and (iv) F and R can't be compared Hence II does not follow.
Correct Answer: S > Q ? R < P
Explanation:
From this expression we cannot deduce any relation between P and S
Correct Answer: ? , =, >
Explanation:
K ? L = M > N
Correct Answer: Only II is true
Explanation:
V < K ...(i) K ? B ...(ii) B > M ...(iii)
From (i) and (ii) V and B can't be compared. Hence I does not follow.
From (ii) and (iii) K ? B > M or K > M or M < K
Hence II follows.
From (i) and (iv) V and M can't be compared. Hence III does not follow.
Correct Answer:
Explanation:
D ? N ...(i) R = F ...(ii) F > T ...(ii)
From (i) and (ii) D ? R = F or D ? F or F ? D.
Hence either I (F = D ) or II (F > D) follows
From (ii) and (iii) R = F > T or R > T or T < R.
Hence III follows.
Correct Answer: None is true
Explanation:
N ? D ...(i) D ? N ...(ii) K > A ...(iii)
Obviously none of these in equations can be combined.
