The speed ratio of Y and Z is 5 : 4. If Y increases his

Statements: M % C & G @ T $ D; W % M # P 

Statements: Q > U = V ≤ X;  R ≥ S ≥ X

Conclusions:

I. U = S

II. V < S

Statements: O > Q < R > P = U ≥ S > T ≥ N

Conclusion

I: S < R

II: U > N

Statements: S * K, T $ K, K @ B

Conclusions:

a) S $ B

b) S @ B

Statements: I > J = K ≥ M; D ≥ F ≤ E = I

Conclusions:

I. M < E

II. D ≥ M

What is the place of question mark (?) in the given expression does the expression L < I and W > L is definitely true?

W = P ≥ M ? L ; P ≤ I

Statement: N < O; Q ≤ P = O; S > P; R ≥ O

Conclusion:

I. S > R

II. R ≥ S

Statements:

V < E ≤ I = O; E ≥ J ≥ S ≥ W; Z ≤ M ≤ W

Conclusions:

I) O > Z

II) O = Z
