How many classes are there in the given picture?

Statements:

A ≥ Z > B ≥ Y; C > B ≥ W

Conclusion:

I. A > W

II. C > Y

Statements: Q $ Z % C # T @ H 

Conclusions: 

I. Z # H 

II. Q © T 

III. H % Z

Statement: X>W=Y>N≤P; W≥Z ;Z ≥P

I. X>Z

II. W≥P

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

Conclusion:

I. C > H

II. C = J

In a certain code CHARM is written as 715$# and AVOID is written as 56@%8. How is CHORD written in that code?

Statements: Q > M > Y < N = H ≥ S < V < R ≤ K

Conclusion

I: K > Y

II: N > S

Statements: H < P = I ≥ M > G < V ≤  U  ≥ A

Conclusion

I: M ≤ P

II: U > M

Statement:X=Y ≥ Z > Q; Y < V ; W < Q

Conclusions:

I. V > W

II. Q > V

Statement: X=Y≤Z>T; T>Q ; X ≥R

I. Z≥R

II. R>Q

Statements: J ≥ K ≥ A = M, K ≥ O > W ≥ X

Conclusion:

I. J ≥ X

II. J > X
