Seven athletes A, B, C, D, E, F and G participate in a race. E is ahead of A but behind F. D is ahead of only two athlete. G is running last. C is running behind only two athlete. F is not the first.

Which athlete is running in the fourth position from behind?

Which of the following symbols should replace (1) and (2), respectively in the given expression in order to make the expression X < H definitely true?

Statement: A < Z > I < B > S = O ≤ N

Conclusions:

I. S= N

II. B > O

Statement: B > C = J; B > S > E; B < N

Conclusion: I. E < C           II. J ≤ E

Statements: K ≥ N = I ≥ H ≤ U; B = S ≤ I

Conclusion: I. B < K II. B = K

Statements: A ≥ B > C < D, E ≥ F ≥ G, D = H ≥ E

Conclusion:

I. B > F

II. D ≥ G

III. C < G

Statements: P @ Q, Q # R, R % S

Conclusions: a) P # R       b) P @ S

Statements: O< V ≤ N = P < S, R = Z ≥ Y = X > O

Conclusions:

I. R > N

II. X > P

III. R > O

Statements: E > G < H > F = I ≥ J > K ≥ D

Conclusion

I: J < H

II: I > D

Which of the following does not make J @ K and R # K definitely not true?

Statement: V > R; C > U > Q; C < R

Conclusion:

I.V > Q

II. V > U
