Question
In the question, assuming the given statements to be
true, find which of the conclusion (s) among given three conclusions is /are definitely true and then give your answer accordingly. Statements: R > S ≥ V ≥ X < T; Y = O > X > U ≥ W Conclusions: I. W < S II. O > T III. R > YSolution
S ≥ V ≥ X > U ≥ W                S > W. Hence conclusion I follows. O > X < T                        No relationship can be established between O and T. Hence conclusion II does not follow. R > S ≥ V ≥ X < O = Y             No relationship can be established between R and Y. Hence conclusion III does not follow.
