- Statements:
D * R, R % F, F S T
Conclusions:
I. F % D II. F S D III. T © R
Options- A. Only I is true
- B. Only II is true
- C. Only III is true
- D. Only either I or II is true
- Correct Answer

ExplanationD ? 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. - 1. Statements:

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:
K ? L = M > N
Correct Answer: S > Q ? R < P
Explanation:
From this expression we cannot deduce any relation between P and S
Correct Answer:
Explanation:
H ? I = J = K ? L < M
Correct Answer:
Explanation:
F < E < J ? H > Z H ? Y and Z < H
Correct Answer: None is true
Explanation:
N ? D ...(i) D ? N ...(ii) K > A ...(iii)
Obviously none of these in equations can be combined.
Correct Answer: Only III is true
Explanation:
N ? T ...(i) T > N ...(ii) N < R ...(iii)
From (i) and (ii) N ? T. Hence II (N ? K) does not follow. From (iii) and (iv) no relationship can be established a between K and R. Hence I does not follow.
Correct Answer: All I, II and III are true
Explanation:
W = K ....(i) K < F ...(ii) D > F ...(iii)
Combining these we get W = K < F < D
Hence D > K and I follows
Again D > W and II follows. Also, F > W
Hence III (F ? W) does not follow.
Correct Answer: Only I and II are true
Explanation:
B ? K ...(i) K < F ...(ii) F = W ...(iii)
Combining these we get B ? K < F = R
Hence R > K and I follows
Again R > B and II follows.
Also, F > B III follow.
Correct Answer: Only II is true
Explanation:
R ? K ...(i) K > M ...(ii) M ? J ...(iii)
From (i) and (ii) J and K can't be compared. Hence I does not follow.
From (i) and (ii) R ? K > M or K > M or M < R.
Hence II is true but III (M = R) is not.
