In a certain language different symbols represent different operators as follows.
- $ means X = Y
- ∏ means X ≤ Y
- ∇ means X ≮ (not less than) Y
- Δ means X < Y
- @ means X > Y
Statements: K @ L; L @ M; M ∏ N;
- K Δ N
- M @ K
both I and II are true.
only conclusion II is true.
only conclusion I is true.
neither I nor II is true.
The statements can be translated to K > L > M ≤ N. Conclusion I translates to K < N. Conclusion II translates to M > K. 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 ≥.
