Question
Statements: M ≤ N = O ≤ P; P = Q ≤ U; R > N =
U Conclusions: I. R > O II. U ≥ M In the question, assuming the given statements to be true, find which of the conclusion (s) among given two conclusions is/are definitely true and then give your answer accordingly.Solution
O ≤ P = Q ≤ U = N < R                    R > O. Hence conclusion I is true. M ≤ N = O ≤ P = Q ≤ U                    U ≥ M. Hence conclusion II is true.
