`'P%Q'` means 'P is neither smaller than nor equal to Q'.
`'Pdiamond, Q '` means 'P is not greater than Q'.
`'P $,Q` means 'P is not smaller 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#M,M $R, R ` @`J,W%J`
Conclusions:
I. `W%R`
II. `M$J`
III. `R%D`
IV. `W%M`

Options

A. Only II and III are true
B. Only I and IV are true
C. Only I and II are true
D. Only III and IV are true

Answer

C

Explanation

`D#MimpliesDltM`
`M$RimpliesMgeR`
R@`JimpliesMgeR`
`W%JimpliesWgtJ`
Therefore,
`D ltM ge R=JltW`
Conclusions:
I. `W%RimpliesWgtR:` True
II. `M$JimpliesMgeJ: `True
III. `R%DimpliesRgtM:` Not True
IV. `W%MimpliesW gtM: Not True
Only conclusion I and II follow.
