Question:medium
A tank has an inlet pipe and an outlet pipe. If the outlet pipe is closed then the inlet pipe fills the empty tank in 8 hours. If the outlet pipe is open then the inlet pipe fills the empty tank in 10 hours. If only the outlet pipe is open then in how many hours the full tank becomes half-full?

Show Hint
In pipe and tank problems, always express rates as work per unit time. The net rate is the sum of filling rates (positiv(e) minus emptying rates (negativ(e).
