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 either smaller than or equal to B.
A `ox` B means A is smaller than B.
A $ B means A is equal to B.
Statements: W @ S, K `ox` Z, U + W, S $ K
Conclusions: I. U @ K II. Z @ S

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: `W gt S, K le Z, U ge W, S = K,`
Conclusions: I. `U gt K` II. `Z gt S`
Combinning `U ge W` and `W gt S` we get `U ge W gt S` which gives `U gt S`. Now, S = K gives `U gt K`. So, I follows. From, `K le Z` and S = K, we get `S le Z` which is different from `Z gt S`.
