In a certain language different symbols represent different operators as follows.
- ∑ means X = Y
- η means X ≯ (not more than) Y
- @ means X ≮ (not less than) Y
- λ means X < Y
- Δ means X > Y
Statements: J @ K; K ∑ L; L @ M;
- J ∑ L
- J Δ K
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 J ≥ K = L ≥ M. Conclusion I translates to J = L. Conclusion II translates to J > K. 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 ≥.
