Direction: In the following questions, the symbols δ, $, ∗ , @ and © are used with the meaning as indicated below.
'P $ Q' means 'P is neither equal to nor greater than Q'.
'P © Q' means 'P is neither equal to nor smaller than Q'
'P δ Q' means 'P is neither greater than nor smaller to Q'.
'P @ Q' means 'P is not smaller than Q'.
'P ∗ Q' means 'P is not greater than Q'.
in each question, three statements showing relationship, have been given , which are followed by three Conclusions I, II and III. Assuming that the given statements to be true, find out which conclusion(s) is/are definitely true.
-
Statements
D $ M, M ∗ B, B δ J
Conclusions
I. J © D
II. B @ D
III. J @ M
-
- I and II are true
- I and III are true
- II and III are true
- I, II and III are true
- None of the above
Correct Option: B
Statements
D $ M ⇒ D < M,
M H B ⇒ M ≤ B, B δ J ⇒ B = J
So, D < M ≤ B = J
Conclusions
I. J © D ⇒ J > D (true)
II. B @ D ⇒ B ≥ D (false)
III. J @ M ⇒ J ≥ M (true)
So, Conclusion I and III are true from the given statements.
