Hello and welcome to exampundit. Here is a set of Reasoning Quiz on Coded Inequalities.

**Directions (Qs.1-5): In the following questions, the symbols @, #, $, * and % are used as illustrated below:**

‘P @ Q’ means ‘P is not smaller than Q’.

‘P # Q’ means ‘P is neither greater than nor equal to Q’.

‘P $ Q’ means ‘P is neither smaller than nor greater than Q’.

‘P * Q’ means ‘P is not greater than Q’.

‘P % Q’ means ‘P is neither smaller than nor equal to Q’.

Now, 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? Give answer

(a) if only Conclusion I is true.

(b) if only Conclusion II is true.

(c) if either Conclusion I or II is true.

(d) if neither Conclusion I nor II is true.

(e) if both Conclusions I and II are true.

**Statements:**

M $ K, D * K, R # K

**Conclusions:**

- D $ M
- M % D

Show Answer

**Option**: C

**Explanation**:

M = K .…. (i);

D ≤ K ….. (ii);

R < K ..… (iii)

From (i) and (ii), we get

M = K ≥ D **–>** M ≥ D

Hence, either M > D (conclusion II) or M = D (conclusion I) is true

**Statements:**

F * M, M % R, E @ F

**Conclusions:**

- M % E
- R @ E

Show Answer

**Option**: D

**Explanation**:

F ≤ M… (i); M > R… (ii); E ≥ F… (iii)

From (i) and (iii), no specific relation can be obtained between M and E. Similarly, no specific relation can be obtained between R and E.

**Statements:**

H $ K, T # H, W * T

**Conclusions:**

- K % W
- T # K

Show Answer

**Option**: E

**Explanation**:

H = K… (i); T < H…(ii),

W ≤ T …(iii)

From (i), (ii) and (iii), we get

K = H > T ≥ W **–>** K > W (conclusion I) and T < K (conclusion II).

**Statements:**

N % A, A # L, F $ N

**Conclusions:**

- L % F
- F % A

Show Answer

**Option**: B

**Explanation**:

N > A… (i), A < L… (ii), F = N…(iii)

From (i) and (iii), we get

F = N > A**–>** F > A (conclusion II). But no specific relation can be obtained between L and F. Hence, conclusion I is not necessarily true.

**Statements:**

B * D, D $ M, F % M

**Conclusions:**

- B # M
- F % B

Show Answer

**Option**: B

**Explanation**:

B ≤ D…(i); D = M…(ii); F > M …(iii)

From (i), (ii) and (iii), we get

F > M = D ≥ B **–>** B < M and F > B (conclusion II).

Since, B < M, therefore, conclusion I is not necessarily true.

**Directions (Qs. 6-11): In the following questions the symbols +, ×, ?, @ and $ are used with the following meanings:**

P + Q means P is neither smaller nor greater than Q.

P × Q means P is neither equal to nor smaller than Q.

P ? Q means P is neither greater than nor equal to Q.

P @ Q means P is either greater than or equal to Q.

P $ Q means P is not equal to Q.

Now, 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. Give answer

(a) if only conclusion I is true;

(b) if only conclusion II is true;

(c) if either I or II is true:

(d) if neither I nor II is true; and

(e) if both I and II are true.

**Statements:**

P $ Q, Q × R, P + R

**Conclusions:**

- Q × P
- P ? Q

Show Answer

**Option**: E

**Explanation**:

P ≠ Q …(i), Q > R … (ii), P = R …(iii)

From (ii) and (iii), we get Q > R = P –> Q > P. Hence, both I and II are true.

**Statements:**

A + B, B $ C, C ? A

**Conclusions:**

- C $ A
- B + C

Show Answer

**Option**: A

**Explanation**:

A = B … (i), B ≠ C … (ii), C < A … (iii)

From (iii), conclusion I is true. II contradicts statement (ii), hence, it is not true.

**Statements:**

Y @ Z, Z × Q, Q $ P

**Conclusions:**

- Y ? Q
- Y ? P

Show Answer

**Option**: D

**Explanation**:

Y ≥ Z …(i), Z > Q … (ii), Q ≠ P …(iii)

From (i) and (ii), we get Y > Z > Q **–>** Y > Q … (A)

Hence, I is not true. From (iii), two possible relationships between P and Q are;

Case I: When P > Q

Now, using (A), we get Y > Q < P **–>** no conclusion.

Case II: When Q > P using (A), we get Y > Q > P **–>** Y > P. Hence, II is not true.

**Statements:**

E × F, F @ L, L+ N

**Conclusions:**

- N + F
- E × L

Show Answer

**Option**: B

**Explanation**:

E > F …. (i), F ≥ L … (ii), L = N …(iii)

From (ii) and (iii), we get F ≥ L= N **–>** F ≥ N or N′ F.

Hence, I may be true but not necessarily so.

From (i) and (ii), we get E > F ≥ L **–>** E > L

Hence, II is true.

**Statements:**

H @ J. J ? K, K × M

**Conclusions:**

- H @ M
- M × J

Show Answer

**Option**: D

**Explanation**:

H ≥ J … (i), J < K … (ii), K > M … (iii)

From (ii) and (iii), we get J < K > M fi no relationship between J and M can be established. Hence, II can’t be established. Again, combining all we can’t conclude the relationship between H and M. Hence, I is not true.

**Statements:**

M @ T, T + V, V ? E

**Conclusions:**

- V + M
- V ? M

Show Answer

**Option**: C

**Explanation**:

M ≥ T … (i), T = V …. (ii), V < E …(iii)

From (i) and (ii), we get

M ≥ T = V –**->** M ≥ V **–>** either V = M or V < M is true.
