Directions (Qs. 16-20): In the follojwing questions, the symbols @, #, $,* and & are used as illustrated below:
‘P # Q’ means ‘P is not smaller than Q’.
‘P $ Q’ means ‘ P is neither smaller than nor greater than Q’.
‘P @ Q’ means ‘P is neither greater than nor equal to Q’.

Now, im each of the following questions assuming the given statements to be true, find which of the two conclusions I and II given below them is/are definitely true? Give answer
Statements: B $ K, K @ D, D # M
Conclusions: I. B $ M
II. B @ M
Answer & ExplanationOption: [D]
B = k.......(i); K < D ......(ii); D > M ..... (iii)
From (i) and (ii), we get
D > K = B .............. (iv)
From (iii) and (iv), no specific relation can be obtained between B and M. Therefore, B = M (conclusion I) and B < M (conclusion II) are not necessarily true.
