`'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#M, M $R, R` @ `J, W%J`
Conclusions :
I. `W%R`
II. `M$J`
III. `A%R`
IV. K#R

Options

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

Answer

A

Explanation

`R$BimpliesRgeB`
B@`AimpliesB=A`
`A%KimpliesA gtK`
`K#MimpliesKltM`
Therefore,
`RgeB=AgtKltM`
Concluslons:
I. `M%AimpliesM gt A:` Not True
II. `K$BimpliesKgeB:` Not true
III. `A%RimpliesAgt R:` Not True
IV. `K#RimpliesKltR:` True
Only conclusion IV follows.
