Question
In a certain language different symbols represent different operators as follows.
- ∧ means X = Y
- ∏ means X ≤ Y
- ∅ means X ≮ (not less than) Y
- Ξ means X < Y
- % means X > Y
Statements: M Ξ N; N ∧ O; O ∧ P;
Conclusions:
- M Ξ P
- N ∧ P
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: a
Ans: a
The statements can be translated to M < N = O = P. Conclusion I translates to M < P. Conclusion II translates to N = P. So we can see that both I and II are true.
Please remember that in such questions ≯ (not more than) is same as ≤, and ≮ (not less than) is same as ≥.
