What should come in place of the question mark (?) in

In which of the following expressions will the expression ‘M ≥ N ' and ‘Q < O’ be definitely true?

Which of the following expressions will be true if the expression ‘D ≥ E < F = G’ is definitely true?

Statements:

P > O ≥ D > M ≤ Y < L; M > G > Q

Conclusions:

I)  O > Q

II) L < G

Statement:

J < K ≤ M > O; M > P < Z; Z = R

Conclusion:

I. P < K

II. R > K

What should come in the place of question mark, in the given expressions to make ‘T > Y’ always true?

R > T = U ≥ V ? W ≥ X =Y

Statements: P < Q = R ≥ S = T; R < U; R = W

Conclusion: I. W ≥ T II. U < P

Statements: T > U ≥ V; W ≥ X < V; X > Y > Z

Conclusions:

I. T > Z

II. V ≥ Y

III. U ≥ X

Statements: M ≥ G > K = Y; A ≥ Z ≥ E > M = I

Conclusions:

I. A ≥ I

II. K < E

III. I > G
