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
M @ D, D δ K, K © R
Conclusions
I. R $ M
II. K δ M
III. K $ M
-
- Only I is true
- Only II is true
- Only III is true
- Either II or III and I are true
- Either II or III is true
Correct Option: D
Statements
M @ D ⇒ M ≥ K,
D δ K ⇒ D = K, K © R ⇒ K > R
So, M ≥ K = D > R
Conclusions
I. R $ M ⇒ R < M (true)
II. K δ M ⇒ K = M ( may be)
III. K $ M ⇒ K < M ( may be)
So, from the given statements either II or III and I are true.
