Question
An inlet pipe can fill an empty tank in 16 minutes whereas
an outlet pipe can empty the fully filled tank in 32 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 32 litres (LCM of 16 and 32)
Efficiency of inlet pipe = (32/16) = 2 litres/minute
Efficiency of outlet pipe = (32/32) = -1 litre/minute
Required time = (0.5 × 32) ÷ (2 - 1) = 16 minutes
