`'P $ Q'` meand 'P' is not smaller then Q'.
'P@Q' means 'P is neither smaller than nor equal to Q'.
`'P#Q'` means 'P is netier greater than nor equal to Q'.
`'P delta Q'` measn 'P is neither greater than nor equal to Q'.
`'P**Q'` means 'P is not greater than Q'.
Now in each of hte following questions assuming the given statements to be true, find which of the four conclusions I, II,III and IV given bwlow them is/are definitely trueand give your answer accordingly.
Stetements:
`NdeltaB,B$W,W#H,H***M`
I.M@W
II.H@N
III.`W deltaN`
IV. `W#N`

Options

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

Answer

D

Explanation

`NdeltaBimpliesN=B`
`B$WimpliesB geW`
`W#HimpliesWltH`
`H***MimpliesHleM`
Conclusions
I. M@W`impliesMgtW`: True
II. H@N `implies H gt N ` : Not true
III. `W deltaNimpliesW=N`: Not true
IV. `W#NimpliesWlt N`: Not true
W is either smaller than or equal to N, Therefore either III or IV and I are true.
