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 Option: C
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.

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 Option: A
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.

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 Option: B
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.

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 Option: C
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.
Direction: In the following information question, the symbol S, %, @, © and are used with the following meaning as illustrated below:
'P % Q' means 'P is smallest than Q'.
'P % Q' means 'P is not greater Q'.
'P * Q' means 'P is neither greater than nor equal to Q'.
'P © Q' means 'P is neither smallest than nor equal to Q'.
'P @ Q' means 'P is neither greater than nor smallest than Q'.

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 Option: D
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.
