Question
Statements: X > U < Y = W ≤ Z = S ≤ N ≥ T > I
Conclusions: I. U ≥ Z II. Y ≤ N In each of the following questions, the relationship between different elements is shown in the statements followed by two conclusions. Find a true conclusion.Solution
X > U < Y = W ≤ Z = S ≤ N ≥ T > I                                 Z > U. Hence conclusion I is not true. X > U < Y = W ≤ Z = S ≤ N ≥ T > I                                Y ≤ N. Hence conclusion II is true.
