Question
An inlet pipe can fill an empty tank in 45 minutes whereas
an outlet pipe can empty the fully filled tank in 60 minutes. Find the time taken by both the pipes together to fill half of the empty tank.Solution
Let the total capacity of tank be 180 litres (LCM of 45 and 60)
Efficiency of inlet pipe = (180/45) = 4 litres/minute
Efficiency of outlet pipe = (180/60) = -3 litres/minute
Required time = (0.5 × 180) ÷ (4 - 3) = 90 minutes
