Question
Pipe A fills a tank in 24 hours. Pipe A and B together
fill it in 8 hours. Pipe B and C together also fill it in 8 hours. Find the time taken by A, B and C together.Solution
ATQ, A = 1/24 B = 1/8 − 1/24 B = (3 − 1)/24 = 2/24 = 1/12 B + C = 1/8 C = 1/8 − 1/12 C = (3 − 2)/24 = 1/24 A + B + C = 1/24 + 1/12 + 1/24 = (1 + 2 + 1)/24 = 4/24 Required time = 24/4 hours = 6 hours
Statement: A ≥ B ≥ C = D > E, F > G = H ≤ CÂ
Conclusion: I. C ≥ F          II. F > D
Statements: Y > U = I; U > H; Z ≤ C ≤ E = Y
Conclusions:
I. U < C
II. E > I
III. I > H
