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.

  1. Statements
    M @ D, D δ K, K © R
    Conclusions
    I. R $ M
    II. K δ M
    III. K $ M
    1. Only I is true
    2. Only II is true
    3. Only III is true
    4. Either II or III and I are true
    5. 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.
