In a certain language different symbols represent different operators as follows.
- © means X = Y
- ∑ means X ≯ (not more than) Y
- Γ means X ≮ (not less than) Y
- ∧ means X < Y
- ∀ means X > Y
Statements: O Γ P; P ∧ Q; Q © R;
- P ∧ R
- Q © R
both I and II are true.
only conclusion II is true.
only conclusion I is true.
either I or II can be true.
The statements can be translated to O ≥ P < Q = R. Conclusion I translates to P < R. Conclusion II translates to Q = R. 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 ≥.
