`xx` means not less than
`=` means greater than
Study the meaning of these symbols and pick up the correct answer from the answer choices for each of the questions below:
`x = y = z` does not imply

Options

A. `y phi x = z`
B. `z phi y phi x`
C. `z phi x = y`
D. `y phi x phi z`

Answer

D

Explanation

According to the meaning of the given symbols , `x = y = z implies x gt y gt z ` i.e., `x gt z`
Using the proper symbols in option ( d) , we get
`y phi x phi z implies y lt x lt z cancelimplies x gt y gt z [ therefore x cancellt z ` i.e., `x gt z`]
Therefore `x = y = z cancelimplies y phi x phi z`.
