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
B © N, N @ R, F ∗ R
Conclusions
I. B © R
II. F ∗ N
III. R $ B
-
- 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: D
Statements
B © N ⇒ B > N,
N @ R ⇒ N ≥ R, F H R ⇒ F ≤ R
So, B > N ≥ R ≥ F
Conclusions
I. B © R ⇒ B > R ( true)
II. F H N ⇒ F ≤ N (true)
III. R $ B ⇒ R < B (true)
So, all I, II and III are true from the given statements.
