### Question

In a certain language different symbols represent different operators as follows.

- ∂ means X = Y
- ∏ means X ≤ Y
- Ξ means X ≥ Y
- √ means X < Y
- ∇ means X > Y

**Statements: **T ∇ U; U ∂ V; V √ W;

**Conclusions: **

- T ∇ V
- U Ξ W

**A**

both I and II are true.

**B**

only conclusion II is true.

**C**

only conclusion I is true.

**D**

either I or II can be true.

**Soln.**

**Ans: c**

The statements can be translated to T > U = V < W. Conclusion I translates to T > V. Conclusion II translates to U ≥ W. So we can see that only conclusion I is true.

Please remember that in such questions ≯ (not more than) is same as ≤, and ≮ (not less than) is same as ≥.
