In a certain language different symbols represent different operators as follows.
- « means X = Y
- @ means X ≤ Y
- Δ means X ≮ (not less than) Y
- % means X < Y
- λ means X > Y
Statements: Q Δ R; R % S; S Δ T;
- Q % T
- T % Q
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 Q ≥ R < S ≥ T. Conclusion I translates to Q < T. Conclusion II translates to T < Q. So we can see that either I or II can be true.
Please remember that in such questions ≯ (not more than) is same as ≤, and ≮ (not less than) is same as ≥.
