Statements : R < O ≤ P < Q; M < L ≤ N > O; S < Q ≤ K

Conclusions:

I. M < K

II. N > R

III. O < S

Statements: E $ N, N * G, H % E

Conclusions: a) G # H     b) H $ N

Statements : B ≤ C < E; D ≤ F ≤ G; E = D; A > B

Conclusions :

(i) E ≥ G (ii) A < E (iii) B ≤ G (iv) C < F

Statement: C > S > F > B > L; I > B > T

Conclusion: I. I > L II. T < C

Statement: C < X ≤ B > E < L < I

Conclusion: I. X > L           II. B > C
