Question
An inlet can fill an empty tank in 6 hours whereas an outlet pipe can empty it in 12 hours. If (N - 1) such outlet pipes having same efficiency and (N + 1) such inlet pipes having same efficiency are opened together, then the tank gets filled in 3 hours. How many inlet pipes are used?
Required number of inlet pipes used = N+1 = 1+1 = 2More Pipes and cisterns Questions
