Conclusions:
I. K © M II. N © D III. M © N
Options- A. Only I is true
- B. Only II is true
- C. Only III is true
- D. Only I and II are true
- Correct Answer
- Only II is true
ExplanationM ? D ...(i) D< K ...(ii) K ? N ...(iii)
From (i) and (ii) K and M can't be compared.
Hence I does not follow.
From (ii) and (iii) D < K ? N or N > D.
Hence II follows. From (i) and II, M and N can't be compared. Hence III does not follow. - 1. Statements:

Correct Answer: Only I and III are true
Explanation:
F ? B ...(i) B = H ...(ii) H ? K ... (iii)
From (i) B F. Hence I follows.
From (ii) and (iii) B = H ? K or B ? K or K ? B can't be compared. Hence II does not follow.
Correct Answer: Only II is true
Explanation:
F ? N ...(i) N < D ...(ii) D ? R ...(iii)
From (i) and (ii) F and can't be compared.
Hence I does not follow.
From (ii) and (iii) N < D ? R or R > N ...(iv)
Hence II follows. From (i) and (iv) R and F can't be compared. Hence III does not follow.
Correct Answer: Only III is true
Explanation:
B = H ...(i) H > E ...(ii) E ? K ...(iii)
From (i) and (ii) B = H > E or E < B
Hence III follows.
From (ii) and (iii) H and K can't be compared.
Hence I does not follow. Nor can II follow.
Correct Answer: None is true
Explanation:
W ? F ...(i) F > M ...(ii) M < D ...(iii)
From (i) and (ii) W and M can't be compared. Hence II does not follow.
From (ii) and (iii) F and D can't be compared. Hence neither I or III follows.
Correct Answer: Only either I or II and III are true
Explanation:
M ? W ...(i) W = N ...(ii) N > B ...(iii)
Combining these we get M ? W = N > B.
Hence M ? N or N ? M,
Which means either I (N = M) or II (N < M) follows.
Also M > B and II (M ? D) Hence III deficitely true.
Correct Answer: if only conclusion II is true
Explanation:
R ? N ...(i) N ? F ...(ii) F > B ...(iii)
From (i) and (ii) F and R can't be compared. Hence I does not follow.
Combing (ii) and (iii) we get N ? F > B or N > B or B < N. Hence II follows.
Correct Answer: if either conclusion I or conclusion II is true
Explanation:
H = W ...(i) W ? R ...(ii) R > F ...(iii)
From (i) and (ii) H = W ? R or R ? H, Hence either I (R = H) or II (R > H) follows.
Correct Answer: if only conclusion I is true
Explanation:
M < T ... (i) T > K ...(ii) K = D ...(iii)
From (ii) and (iii) T > K = D or D < T.
Hence I follow
From (i) and (ii) K and M can't be compared
Hence II does not follow
Correct Answer: if neither conclusion I nor conclusion II is true
Explanation:
H > W ...(i) W > M ..(ii) M ? K ....(iii)
From (ii) and (iii) K and W can't be compared
Hence I does not follow.
From (i) and (ii) H and M can't be compared
Hence II does not follow
Correct Answer: if neither conclusion I nor conclusion II is true
Explanation:
F ? K ...(i) K > B ....(ii) B ? M ...(iii)
From (i) and (ii) F can't be compared with B and consequently with M. Hence neither II nor I follows.
