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: M > N ≥ O = P; Q > U > T ≥ S = R ≥ P Conclusions: I. M > R II. R ≤ U III. Q > PSolution
R ≥ P = O ≤ N < M                                      No relationship can be established between M and R. Hence conclusion I is not true.    U > T ≥ S = R                        U > R. Hence conclusion II is not true. Q > U > T ≥ S = R ≥ P                                Q > P. Hence conclusion III is true.
