Question 1

In a certain language different symbols represent different operators as follows.

  1. © means X = Y
  2. « means X ≤ Y
  3. ∇ means X ≮ (not less than) Y
  4. ® means X < Y
  5. √ means X > Y

Statements: K √ L; L √ M; M √ N;

Conclusions:

  1. K ® M
  2. L √ N
 A

both I and II are true.

 B

only conclusion II is true.

 C

only conclusion I is true.

 D

either I or II can be true.

Soln.
Ans: b

The statements can be translated to K > L > M > N. Conclusion I translates to K < M. Conclusion II translates to L > N. So we can see that only conclusion II is true.

Please remember that in such questions ≯ (not more than) is same as ≤, and ≮ (not less than) is same as ≥.


Question 2

In a certain language different symbols represent different operators as follows.

  1. ∀ means X = Y
  2. Ω means X ≯ (not more than) Y
  3. ⊕ means X ≮ (not less than) Y
  4. ® means X < Y
  5. Θ means X > Y

Statements: F ∀ G; G Θ H; H ∀ I;

Conclusions:

  1. F Θ H
  2. I ® G
 A

both I and II are true.

 B

only conclusion II is true.

 C

only conclusion I is true.

 D

either I or II can be true.

Soln.
Ans: a

The statements can be translated to F = G > H = I. Conclusion I translates to F > H. Conclusion II translates to I < G. So we can see that both I and II are true.

Please remember that in such questions ≯ (not more than) is same as ≤, and ≮ (not less than) is same as ≥.


Question 3

In a certain language different symbols represent different operators as follows.

  1. ω means X = Y
  2. ∩ means X ≤ Y
  3. ∑ means X ≥ Y
  4. λ means X < Y
  5. Δ means X > Y

Statements: T λ U; U λ V; V ω W; W ω X;

Conclusions:

  1. U λ X
  2. V ω X
  3. T λ V

Which of the above conclusions is/are true?

 A

All.

 B

both I and II.

 C

II only.

 D

both II and III.

Soln.
Ans: a

The statements can be translated to T < U < V = W = X.

The conclusions translate to:

  1. U < X(True)
  2. V = X(True)
  3. T < V(True)

Question 4

In a certain language different symbols represent different operators as follows.

  1. √ means X = Y
  2. ¢ means X ≯ (not more than) Y
  3. £ means X ≥ Y
  4. ∧ means X < Y
  5. ∀ means X > Y

Statements: N √ O; O √ P; P ∧ Q;

Conclusions:

  1. N ∧ Q
  2. O ∀ Q
 A

both I and II are true.

 B

only conclusion II is true.

 C

only conclusion I is true.

 D

either I or II can be true.

Soln.
Ans: c

The statements can be translated to N = O = P < Q. Conclusion I translates to N < Q. Conclusion II translates to O > Q. So we can see that only conclusion I is true.

Please remember that in such questions ≯ (not more than) is same as ≤, and ≮ (not less than) is same as ≥.


Question 5

In a certain language different symbols represent different operators as follows.

  1. λ means X = Y
  2. µ means X ≯ (not more than) Y
  3. ® means X ≥ Y
  4. Γ means X < Y
  5. © means X > Y

Statements: L ® M; M Γ N; N µ O;

Conclusions:

  1. M © O
  2. L © O
 A

both I and II are true.

 B

only conclusion II is true.

 C

only conclusion I is true.

 D

neither I nor II is true.

Soln.
Ans: d

The statements can be translated to L ≥ M < N ≤ O. Conclusion I translates to M > O. Conclusion II translates to L > O. So we can see that neither I nor II is true.

Please remember that in such questions ≯ (not more than) is same as ≤, and ≮ (not less than) is same as ≥.
