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'.

M ≥ 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.Correct Option: B
M ≥ D ...(i) D< K ...(ii) K ≤ N ...(iii)
From (i) and (ii) K and M can't be compared.

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 Option: B
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.
