Question
Statements: B & A, A # O, O $ Z, Z @ S
Conclusions: I. Z $ A II. Z & A In the following question, the symbols $, @, & , % and # are used with the following meanings as illustrated below: βR $ Sβ means βR is neither greater than nor smaller to SβΒ βR @ Sβ means βR is neither greater than nor equal to S βR & Sβ means βR is neither smaller than nor equal to S βR % Sβ means βR is not smaller than Sβ βR # Sβ means βR is not greater than S Now, in each of the following questions assuming the given statement to be true, find which of the two conclusions I and II given below them is/are true. Answer.Solution
Decoded statement: B > A, A β€ O, O = Z, Z < S Decoded conclusion: I. Z = A II. Z > A Combined Inequalities: B > A β€ O = Z < S B > A β€ O = Z < S β€ Z. Hence either conclusion I or II is true.
