`'P%Q'` means 'P is neither smaller than nor equal to Q'.
`'Pdiamond, Q '` meand 'P is not greater than Q'.
`'P $,Q` means 'P is not greater than Q'.
`'P#Q'` means 'P is neither greater than nor equal to Q'
'P @Q' means 'P is neither greater than nor smaller than Q'.
Statement
`D diamond, R#M, M` @ `K,K %F`
Conclusitons:
I. `F$M`
II. K @R
III. `K%R`
IX. D@M

Options

A. None is true
B. Only I is true
C. Only II is true
D. Only I is true

Answer

D

Explanation

`D deamondRimpliesD leR`
`R#MimpliesRltM`
M@`KimpliesM=K`
`K%FimpliesKgtF`
Therefore,
`DleRltM=KgtF`
Conclusions:
I. `F$mimpliesFgeM: `Not True
II. K@R`impliesK=R:` Not True
III. `K%RimpliesKgtR: `True
IV. D@M`impliesD=M:` Not True
