### Question

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;

**Conclusions: **

- K Δ N
- M @ K

**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 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 ≥.
