Direction: In the following questions, the symbol @ , $, *, # and δ 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 δ Q’ means ‘P is neither greater than nor smaller than Q’.
‘P * Q’ means ‘P is not greater than Q’.
