In the questions given below, certain symbols are used with the following meanings:'A@B' means 'A is greater than B'.'A*B' means 'A is either greater than or equal to B'.'A#B' means 'A is equal to B'.'A$B' means 'A is either smaller than or equal to B'.'A+B' means 'A is smaller than B'.Statements: P $ Q, N # M, M @ R, R * PConclusions: !. P + N II Q $ M
Options:
A . if only conclusion I is true.
B . if only conclusion II is true.
C . if either conclusion I or II is true.
D . if neither conclusion I nor II is true.
E . if both the conclusions I and II are true.
Answer: Option A
P ≤ Q -- (i); N = M -- (ii); M > R -- (iii); R ≥ P -- (iv)From (ii), (iii) and (iv), we get N = M > R ≥ P=> N > P or P < N. Hence, I is true.From (ii), (iv) and (i), we get, M > R ≥ P ≤ Q => No conclusion about the relationship between M and Q can be established.
