Statements: R ≥ S = T; R < U < V; W > X > V

Conclusion:

I. U > T

In which of these expression ‘O ≤ F’ is definitely true?

Statements : Q = R; S ≥ T; P ≤ Q; R > V; R > S; T ≥ U

Conclusions :

(i) R > U (ii) V ≥ U (iii) P = R (iv) P < R

Statements: V = W ≤ X > R ≥ O; C < O; F = X

Conclusion: I. F > R II. X > C

Statements: I > D > J < E; C > J > K; G < K > A

Conclusions:

I. I > A

II. G < E

III. D ≥ K

Statements: A $ B @ D & E @ G % H, F & A, G $ J

Conclusions: I.F & E II. J # B

Statements: Y ≥ Q ≥ P = T; T ≤ H < O; O > I

Conclusions:

I. P ≥ O

II. I > P

III. T < Y
