Question 1

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

  1. ∀ means X = Y
  2. ∧ means X ≤ Y
  3. ∑ means X ≥ Y
  4. © means X < Y
  5. £ means X > Y

Statements: C ∀ D; D £ E; E © F; F © G;

Conclusions:

  1. E £ G
  2. G © C
  3. G £ D

Which of the above conclusions is/are true?

 A

Neither of the three.

 B

I only.

 C

II only.

 D

III only.

Soln.
Ans: a

The statements can be translated to C = D > E < F < G.

The conclusions translate to:

  1. E > G(False)
  2. G < C(False)
  3. G > D(False)

Question 2

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

  1. § means X = Y
  2. ® means X ≤ Y
  3. λ means X ≥ Y
  4. η means X < Y
  5. % means X > Y

Statements: I § J; J % K; K % L; L § M;

Conclusions:

  1. M η I
  2. J % M
  3. L η I

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 I = J > K > L = M.

The conclusions translate to:

  1. M < I(True)
  2. J > M(True)
  3. L < I(True)

Question 3

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

  1. Γ means X = Y
  2. % means X ≯ (not more than) Y
  3. √ means X ≥ Y
  4. ∂ means X < Y
  5. $ means X > Y

Statements: L √ M; M ∂ N; N ∂ O;

Conclusions:

  1. O $ M
  2. M √ O
 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 L ≥ M < N < O. Conclusion I translates to O > M. Conclusion II translates to M ≥ O. 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 4

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

  1. ∂ means X = Y
  2. ρ means X ≤ Y
  3. ∅ means X ≥ Y
  4. Ξ means X < Y
  5. Γ means X > Y

Statements: N ∂ O; O ∂ P; P ∂ Q; Q Γ R;

Conclusions:

  1. N Γ P
  2. R Ξ O
  3. Q Ξ N

Which of the above conclusions is/are true?

 A

both II and III.

 B

I only.

 C

II only.

 D

III only.

Soln.
Ans: c

The statements can be translated to N = O = P = Q > R.

The conclusions translate to:

  1. N > P(False)
  2. R < O(True)
  3. Q < N(False)

Question 5

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

  1. ⊗ means X = Y
  2. ∃ means X ≤ Y
  3. @ means X ≥ Y
  4. % means X < Y
  5. ∏ means X > Y

Statements: A % B; B % C; C ⊗ D; D ⊗ E;

Conclusions:

  1. E % C
  2. C ∏ A
  3. D ∏ A

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 A < B < C = D = E.

The conclusions translate to:

  1. E < C(True)
  2. C > A(True)
  3. D > A(True)
