Mathematical operation and symbol notation
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 smallest than nor equal to Q'.
'P S Q' means 'P is neither greater than nor equal to Q'.
'P © Q' means 'P is neither smallest than greater nor greater than Q'.
In each of the following questions assuming the given statements to be true, find which of the two conclusions I and II given below them is are definitely true.
 Statements:
R % N, N # F, F @ B
Conclusions:
I. F © R II. B S N

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.
 Statements:
H © W, W % R, R @ F
Conclusions:
I. R © H II. R @ H

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 Option: C
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.
 Statements:
M S T, T @ K, K © D

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 followCorrect Option: A
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
 Statements:
H @ W, W S M, M # K
Conclusions:
I. K S W II. H @ M

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 followCorrect Option: D
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.

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.Correct Option: D
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.
