Question

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

  1. ∧ means X = Y
  2. ρ means X ≤ Y
  3. ∑ means X ≮ (not less than) Y
  4. Θ means X < Y
  5. ¥ means X > Y

Statements: B ρ C; C ∧ D; D ρ E;

Conclusions:

  1. B ¥ D
  2. E Θ B
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 B ≤ C = D ≤ E. Conclusion I translates to B > D. Conclusion II translates to E < B. 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 ≥.
