A `ox` B means A is smaller than or equal to B.
Statements: N $ Y, M © P, O @ N, M `ox` Y
Conclusions: I. O @ M II. Y © P

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

A

Explanation

Statements: `N = Y, M lt P, O gt N, M le Y`
Conclusions: I. `O gt M` II. `Y lt P`
From `O gt N` and N = Y we have `O gt Y`. This combines with `M le Y` to give `O gt Y ge M` to giv `O gt M`. For II, a relevant pair is `M lt P` and `M le Y` but they can.t be combined because M is the lesser term in both the cases here and this violates golden rule 2
