`'P%Q'` means 'P is not smaller than Q'. `'P**Q'` mensa 'P is neither greater than nor equal to Q'. `'P deltaQ'` means 'P is neither smaller than nor equal to Q'. `'P$Q'` menas 'P is neither greater than nor smaller than Q'. 'P© Q' means 'P is not greater than Q'. Now, in each of the following questions assuming the given statements to be true. find which of the two conclusions I and II given below them is/are definitely true. Given answer Statements: `B**K, K$N, N%R` Conclusins: `I. R$K II R**K`

Options

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

Answer

C

Explanation

`B**KimpliesBlt K`
`k$NimpliesK=N`
`N%RimpliesNge R`
Therefore, `B ltK=Nge R`
Conclusions:
I. `R$KimpliesR=K` (False)
II. `R**KimpliesR ltK`(True)
