Question
Pipe 'A' takes 18 minutes to fill half the tank. Pipe
'B' is 3 times as efficient. What percentage of the tank will both fill in 9 minutes?Solution
Full tank time = 18 × 2 = 36 minutes Efficiency of pipe 'A' = x units/min Tank capacity = 36x units Pipe 'B' efficiency = 3x units/min Work in 9 minutes = (x + 3x) × 9 = 36x units Percentage = (36x / 36x) × 100 = 100%
