Question
In the question, relationship between some elements is
shown in the statements (s). These statements are followed by two conclusions. Read the statements and given answer. Statements: F > H ≥ J; D ≤ A < K; F = A ≤ L Conclusions: I. D < F II. K > H III. J < ASolution
D ≤ A = F                                           D ≤ F. Hence conclusion I is not true. K > A = F > H                   K > H. Hence conclusion II is true K > A = F > H ≥ J                              A > J. Hence conclusion III is true.
