At what latitude does the easterly jet stream blow over

Statements: Q $ Z % C # T @ H 

Conclusions: 

I. Z # H 

II. Q © T 

III. H % Z

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

Conclusions:

(i) I > F

(ii) B ≤ H

Statements:

S ≥ T ≤ D > P; F ≥ T > J ≥ Y

Conclusions:

I) Y < S

II) F > P

Statement: X > Y > Z; A > C > X; A < D

Conclusion: I. Z < A            II. C > Y

Statement: C ≥ D > E < F ≥ G; D ≥ H = J

Conclusion:

I. C > H

II. C = J

Statements:

R ≤ S = T; P < Q = R; S < U ≤ V; W ≥ V

Conclusions:

I).  P < U

II).  W > R

Statement: F ≥ G > I > E ≤ P, E = S ≥ P 

Conclusion: I. F ≥ PII. G > P

Statements:

A < L ≤ P > D; F > W = P > S ≥ T

Conclusion:

I. S > L

II. F ≥ A
