In the following questions, the Symbols @, ©, $ , % and & are used with the following meanings as illustrated below.

‘A $ B’ means ‘A is not greater than B’.

'A @ B' means 'A is neither smaller then nor equal to B'.

'A & B' means 'A is neither greater than nor equal to B'.

'A © B' means 'A is neither greater than nor smaller than B'.

'A % B' means 'A is not smaller than B’.

In each of the following question assuming the given statements to be true, find out which of the two conclusions I and I I given below these are definitily true.

- 5.
**Statements:**

C & D, D $ E, E © F

**Conclusions:**

I .F @ C

II. E @ C

A.) If only conclusion I is true

B.) If only conclusion II is true

C.) If either conclusion I or conclusion II is true

D.) If both conclusions I and II are true.

Answer: Option 'D'

‘A $ B’ -> A !> B, therefore A = B.

‘A @ B’ -> A B.

‘A & B’ -> A !> B and A ‘A © B’ -> A !> B and A ‘A % B’ -> A C & D -> C < D

D $ E -> D = E

E © F -> E = F

Therefore C < D = E = F

Conclusions:

1. F @ C -> F > C ( True )

2. E @ C -> E > C ( True )

- 6.
**Statements:**

D % H, H $ P, P @ Q

**Conclusions:**

I .D @ P

II. Q & H

A.) If only conclusion I is true

B.) If only conclusion II is true

C.) If either conclusion I or conclusion II is true

D.) If neither conclusion I nor conclusion II is true

Answer: Option 'D'

D & H -> D = H

H $ P -> H = P

P @ Q -> P > Q

Therefore D = H = P > Q

Conclusions:

1. D @ P -> D > P ( Not True )

- 7.
**Statements:**

A © B, B % C, C & D

**Conclusions:**

I. C & A

II. C © A

A.) If only conclusion I is true

B.) If only conclusion II is true

C.) If either conclusion I or conclusion II is true

D.) If neither conclusion I nor conclusion II is true

Answer: Option 'C'

A © B -> A = B

B % C -> B = C

C & D -> C < D

Therefore A = B = C < D

**Conclusions: **

1. C & A -> C < A ( Not True )

2. C © A -> C = A ( Not True )

C is either smaller than or equal to A. Therefore, either conclusion I or conclusion II is follows

**Instructions : -(8 - 10)**

In the following questions, the Symbols @, ©, $ , % and # are used with the following meanings as illustrated below.

H % J, J © N, N @ R

**Conclusions:**

I. R % J

II. H @ J

III. N @ H

A.) Only II is true

B.) Only I and III are true

C.) Only I is true

D.) Only III is true

Answer: Option 'B'

I)A $ B means A not a lessthan B Therefore, A = B

II) A # B means A not a greater than B Therefore, A = B

III) A @ B means A not a lessthan B and A ? B Therefore, A = B

IV) A © B means A not a lessthan B and A !> B Therefore, A = B

V ) A % B means A not a greater than B and A ? B Therefore, A < B

H % J -> H < J

J © N -> J = N

N @ R -> N > R

Therefore, H < J = N > R

Conclusions:

I. R % J -> R < J ( True )

II. H @ J -> H > J ( Not true)

III. N @ J -> N > H (True)

- 9.
**Statements:**

M @ J, J $ T, T © N

**Conclusions:**

I. N # J

II. T % M

III. M @ N

A.) Only I and II are true

B.) Only II and III are true

C.) Only I and III are true

D.) All are true

Answer: Option 'D'

M % J -> M > J

J $ T -> J = T

T © N -> T = N

Therefore, M > J = T = N

Conclusions:

I. N # J -> N = J ( true )

II. T % M -> T < M ( true)

III. M @ N -> M > N ( true)

- 10.
**Statements:**

D © K, K # F, F @ P

**Conclusions:**

I. P @ D

II. K # P

III. F $ D

A.) Only II is true

B.) Only I and II are true

C.) Only III is true

D.) Only II and III are true

Answer: Option 'C'

D © K -> D = K

K # F -> K = F

F @ P -> F > P

Therefore, D = K = F > P

Conclusions:

I. P @ D -> P > D ( Not true )

II. K # P -> K = P ( Not true )

III.F $ D -> F = D ( True )
