Question
Statements:Â Q $ Z % C # T @ HÂ
Conclusions: I. Z # H II. Q © T III. H % Z In the following questions, the symbols @, #, %, $ and © are used with the following meaning as illustrated below- ‘A # B’ means ‘A is neither greater than nor equal to B’  ‘A © B’ means ‘A is neither equal to nor smaller than B’  ‘A % B’ means ‘A is neither smaller than nor greater than B’  ‘A $ B’ means ‘A is not smaller than B’  ‘A @ B’ means ‘A is not greater than B’ÂSolution
Decoded Statement: Q ≥ Z = C < T ≤ H Decoded conclusion:  I. Z < H                     II. Q > T                                III. H = Z Q ≥ Z = C < T ≤ H                              H > Z. Hence conclusion I is true but conclusion III is not true. Q ≥ Z = C < T ≤ H                               No relationship can be established between Q and T. Hence conclusion II is not true.
