Question
If “M % N # O © P @ S © T $ W” is true then which
of the following is definitely not true? (i) M # P (ii) O © T (iii) N # P (iv) S % W In the following questions, the symbols @, #, %, $ and © are used with the following meaning as illustrated below: ‘A @ B’ means ‘A is neither smaller than nor equal to B’. ‘A # B’ means ‘A is neither greater than nor equal to B’. ‘A % B’ means ‘A is not greater than B’. ‘A $ B’ means ‘A is not smaller than B’. ‘A © B’ means ‘A is neither smaller than nor greater than B’.Solution
M ≤ N < O = P > S = T ≥ W (i) M # P → M < P (M ≤ N < O = P ) it is true. (ii) O © T → O = T (O = P > S = T) it is not true. (iii) N # P → N < P (N < O = P) it is true. (iv) S % W → S ≤ W (S = T ≥ W) it is not true.
