Mathematical operation and symbol notation
Direction: In the following information question, the symbols @, ©, S, % and are used with the following meaning as illustrated below:
'P © Q' means 'P is either greater than or equal to Q'.
'P % Q' means 'P is either smallest than or equal to Q'.
'P @ Q' means 'P is neither smallest than nor greater to than Q'.
'P S Q' means 'P is smallest than Q'.
'P δ Q' means 'P is greater than Q'.
Now each of the following questions assuming the given statement to be true, find which of the three conclusions I and II given below them is are definitely true.
 Statements:
B @ N, N © T, T S K
Conclusions:
I. T @ B II. T S B

B = N ...(i) N ≥ T ...(ii) T > K ...(iii)
From (i) and (ii) B = N ≥ T or T ≤ B,
Hence I either (T = B) or II (T < B) followsCorrect Option: C
B = N ...(i) N ≥ T ...(ii) T > K ...(iii)
From (i) and (ii) B = N ≥ T or T ≤ B,
Hence I either (T = B) or II (T < B) follows
 Statements:
H © T, T % M, M δ F
Conclusions:
I. F S T II. H δ M

H ≥ T ...(i) T ≤ M ...(ii) M > F ...(iii)
From (i) and (ii) H and M can't be compared. Hence II does not follow
From (ii) and (iii) F and T can't be compared. Hence I does not followCorrect Option: D
H ≥ T ...(i) T ≤ M ...(ii) M > F ...(iii)
From (i) and (ii) H and M can't be compared. Hence II does not follow
From (ii) and (iii) F and T can't be compared. Hence I does not follow

After replacing all the symbol from question.
44 x 9 ÷ 12  6 x 4 + 16 = ?
Apply BODMAS rule,
⇒ 44 x 9 x 1/12  24 + 16 = ?Correct Option: C

From option (c),
24 = 34 ÷ 2  5 + 12
⇒ 24 = 17  5 + 12
⇒ 24 = 29  5
→ 24 = 24Correct Option: C

After replacing the sign according to the question
32 D 4 B 7 C 2 A 6
= 32 ÷ 4 + 7 x 2  6 = 8 + 7 x 2  6Correct Option: D
32 D 4 B 7 C 2 A 6
= 32 ÷ 4 + 7 x 2  6 = 8 + 7 x 2  6
= 8 + 14  6 = 22  6 = 16
