(Q.No: 9-10) In the following questions the symbols 2, $, *, # 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’.
