`'X DeltaY'` means 'X' is neither greater than nor equal to Y.
`'X sum Y` means 'X is not smaller than Y.
'X@Y ' means 'X is not greater than Y'.
'X © Y' means 'X is neither greater than nor smaller than Y'
`'X #Y'` means 'X is neither smaller than nor equal to Y.
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 definitely true?
Statements :
R,@ `J, F sum J, C sum F`
Conclusions
I. R (c) C
II. `C#R`

Options

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

Answer

C

Explanation

Statements:
R@J `impliesR le J`
`F sum J impliesF geJ`
`Csum Fimplies C geF`
Therefore,
`R le J le F le C`
Conclusions:
I. R©C`impliesR=C`: True
II. `C#RimpliesC gt R:` True
So either conclusion I or II is true.
