Direction: In the following questions, the symbols $,@,#,^ and * are used with the following meaning as illustrated below.
'P $ Q' means 'P is not smaller than Q'.
'P @ Q' means 'P is neither smaller than nor equal to 'Q
'P # Q' means 'P is neither greater than nor equal to Q'.
'P ^ Q' means 'P is neither greater than nor smaller than Q'.
'P * Q' means 'P is not greater than Q'.
Now in each of the following questions assuming the given statements to be true, find which of the four conclusions I, II, III and IV given below them is/are definitely true and give your answer accordingly.
Statements: M $ K, K @ N, N * R, R # W
Conclusions:
I. W @ K
II. M $ R
III. K @ W
IV. M @ N
From the question M ≥ K > N ≤ R < W
The conclusions given are W > K , M ≥ R , K < W , M > N
We know that both W and K are greater than N, but the relationship between the two of them is not known. Hence, the first conclusion is wrong.
Similarly, M and R are greater than N, but the relationship between the two of them is not known.
Similarly, K and W are greater than N, but the relationship between the two of them is not known.
M is greater than or equal to K which is in turn greater than N, hence M > N and the fourth conclusion is correct.
So, of the four options, none of them is correct.
