Question
Statements: R = F > Q = Y > B; J < Z ≤ Y
Conclusions: I. Q > Z II. B ˃ J In the following questions assuming the given statements to be true, find which of the conclusion among given conclusions is/are definitely true and then give your answers accordingly.Solution
Given statements: R = F > Q = Y > B; J < Z ≤ Y On combining the given statements: R = F > Q = Y ≥ Z > J Conclusions: I. Q > Z → False (as Q = Y ≥ Z) II. B > J → False (as B < Y ≥ Z < J) → thus relation between B and J cannot be determined. Hence, neither conclusion I nor II is true.
