A @ B means A is greater than B.
A + B means A is either greater than or equal to B.
A Ɨ B means A is smaller than B.
A `ox` B means A is smaller than or equal to B.
A $ B means A is equal to B.
Statements: R + N, S `ox` B, A @ `alpha,` B $ A
Conclusions: I. S $ N II. A @ N

Options

A. If only I is true
B. if only conclusion II is true
C. if either conclusion I or II is true
D. if either I nor II is true

Answer

D

Explanation

Statements: `R ge N, S le beta, A gt alpha, B = A`
Conclusions: I. S = N II. `A gt N`
I is wrong as there are no equalities involving S or N in the given statements. II can.t be established as there are no relevant statements that can be linked to get a conclusion between A and N.
