Question

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

  1. Θ means X = Y
  2. Γ means X ≤ Y
  3. ∇ means X ≮ (not less than) Y
  4. « means X < Y
  5. √ means X > Y

Statements: R Θ S; S « T; T √ U;

Conclusions:

  1. R Θ U
  2. T √ R
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: b

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

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