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’ Now in each of the following questions assuming the given statement to be true, find which of the three conclusions I, II and III given below them is/are definitely true and give your answer accordingly.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.
