P© Q' means P' is not smaller than Q'.
`'P%Q'` means 'P is neither smaller than nor equal to Q'.
`'P**Q'` measn 'P is not greter than nor equal to Q'.
`'PdeltaQ'` means P is not greater than Q'.
'P @Q' means 'P is neither greater than nor smaller than Q'.
Now in each of hte following questions assuming the given statements to be true, find which of the four conclusion I, II, II and IV. given below them is/are definitely trueand given your answer accordingly.
Statements: `R**K,K%D,D`@`V,VdeltaM`
Conlucions:
`I. R**D`
II. `V**R`
III. D@M
IV. `M%D`

Options

A. None is true
B. Only III is true
C. Only IV is true
D. Only either III or IV is true

Answer

D

Explanation

`R**K impliesRltK`
`K%DimpliesKgtD`
D@`VimpliesD=V`
`V delta M impliesV le M`
Therefore, `R ltK gt D=V leM`
Conclusions
I. `R**DimpliesR lt D`:Not True
II. `V**RimpliesVlt R` : Not True
III. D@M `impliesD=M`: Not true
IV. `M%DimpliesMgt D`:Not True
D is either smaller than or ewual to M. Therefore, either III or IV follows.
