Pipe 'A' fills half tank in 25 minutes. Pipe 'B' is 3
times as efficient. What percentage of the tank is filled by both in 10 minutes?Solution
Full tank time = 25 × 2 = 50 minutes A’s efficiency = x units/min Tank capacity = 50x units B’s efficiency = 3x units/min Work in 10 minutes = (x + 3x) × 10 = 40x units Percentage = (40x / 50x) × 100 = 80%
