`A#B` means A is neither greater than nor equal to B
`A©B` means A is neither equal to nor smaller than B
`A%B` means A is neither smaller than nor greater than B
`A$B` means A is not smaller than B.
A@B means A is not greater than B
Now, in each of the following questions, assuming the given statements to be true, find which of the two conclusions I and II given below them is/are true. Give answer.
Statements: `Z#F,` R@F, `D©R`
Conclusions: I. `Z#R` II. `D©Z`

Options

A. if only Conclusion I is true.
B. if only Conclusion II is ture.
C. if either Conclusion I or II is true.
D. if neither Conclusion I nor II is true.

Answer

D

Explanation

`A#BrarrAltB`
`A©BrArrAgtB`
`A%BrArrA=B`
`A$BrArrAgeB`
A@B`rArrAleB`
`Z#F,` R@F, `D©R`
`ZltF, RleF, DgtR`
I. `ZltR(x)`
II. `DgtZ(x)`
Combining the given expressions,
`DgtRleFgtZ`
so, neither I nor II is true.
