Let the total capacity of tank be 550 units Efficiency of pipe ‘A’ = 550/22 = 25 units/hour Efficiency of pipe ‘B’ = 550/25 = 22 units/hour Tank filled in 2 hours = (25 – 22) = 3 units Therefore, tank filled in (2 × 27.5 = 55 hours) = 3 × 27.5 = 82.5 units Required percentage of tank filled = (82.5/550) × 100 = 15%
