Ans:D

  1. In the question symbols *, @, %, $ and # are used with the following meaning :

‘P $ Q’ means ‘P is not greater 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’
‘P % Q’ means ‘P is not smaller than Q’.
‘P @ Q’ means ‘P is neither smaller than nor equal to Q’.
Now assuming the statements to be true, find which of the
two conclusions I and II is/are definitely true.
Statements:
W @ M, J # M, M * Y
Conclusions:
