Question
In which of the following expression will the
expression ′A ≤ D ′ does not hold true? In these questions, relationship between different elements is shown in the statements. These statements are followed by five conclusions. Read the statements and then decide which of the following conclusion follow from the given statements.Solution
A ≤ B = C ≤ D ≤ E               A ≤ D is true. Hence option 1 is incorrect. B > F = D ≥ G ≥ A              A ≤ D is true. Hence option 2 is incorrect. C < D = E ≥ F = A               A ≤ D is true. Hence option 3 is incorrect. D < B ≥ E = O ≥ A              A ≤ D is false. Hence option 4 is correct. A ≤ E = B ≤ D < F               A ≤ D is true. Hence option 5 is incorrect.
