A tank is filled by two pipes in 19 min and 25 min respectively, and drained by a third pipe in 31 min. How long to fill the tank if all operate together?
Answer:
16.56
Step-by-step solution: 1. Filling rates: 1/19 + 1/25. 2. Draining rate: 1/31. 3. Net rate = 1/19 + 1/25 - 1/31 = 0.0604 tank/min. 4. Time = 1 / net rate = 16.56 minutes.

A tank is filled by two pipes in 15 min and 21 min respectively, and drained by a third pipe in 31 min. How long to fill the tank if all operate together?
Answer:
12.19
Step-by-step solution: 1. Filling rates: 1/15 + 1/21. 2. Draining rate: 1/31. 3. Net rate = 1/15 + 1/21 - 1/31 = 0.0820 tank/min. 4. Time = 1 / net rate = 12.19 minutes.
