Question
Statements: J © K * R, U % R $ ZÂ
Conclusions: I. Z $ J II. U % K III. U © J In the following questions, the symbols @, ©, %, * and $ are used with the following meaning as illustrated below:   ‘E © F’ means ‘E is not greater than F’.  ‘E $ F’ means ‘E is not smaller than F’. ‘E @ F’ means ‘E is neither smaller than nor greater than F. ‘E * F’ means ‘E is neither equal to nor greater than F’. ‘E % F’ means ‘E is neither smaller than nor equal to F’. Now in each of the following questions, assuming the given statements to be true, find which of the three conclusions I, II and III given below them is/are definitely true and give your answer accordinglyÂSolution
Combined Inequality: J ≤ K < R, U > R ≥ Z Decoded conclusion: I. Z ≥ J                         II. U > K              III. U ≤ J J ≤ K < R ≥ Z                                      No relationship can be established between Z and J. Hence conclusion I is not true. J ≤ K < R < U                                     U > K.   Hence conclusion II is true. J ≤ K < R < U                                     U > J. Hence conclusion III is not true
