Present ages of P and Q are in the ratio 4:7 respectively. If Q’s age, 15 years hence from now will be 6 times of P’s age, 6 years ago from now, then find the present age of Q.

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 : T % W % B $ I @ L 

Conclusions : 

I. B * T 

II. L © B 

III. L * T

Statements: P # B, Q $ B, B @ J, J % F

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

Conclusions:

I. P > U

II. R < V

III. T < S

Statement- 1 - A ˂ B ˃ C ≥ F

2 - E ˃ B ≤ D ≠ G

Conclusions:

E > F

G ≥ B

D ˃ A

Statements: J > M < C ≤ S < Q = K > N

Conclusion 

I. J ≥ S

II. N > M

Statements: U > H ≥ W; S > T ≥ B; S < H; C ≤ D = U

Conclusions:

I. D > B

II. T < U

III. W ≤ D

Statements: D % E, E & A, A @ B, B # C

Conclusions: I. C & A                       II. D # B

Statement: J `>=` I > P `<=` Q 

    Conclusion: I. P < J                       II. Q `>=` J

Statement: P > Q ≥ R = S ≤ T < U

Conclusions: I. T > Q II. U < P
