Video Transcription

Number six. Container A holds 10 liters of water. All five plugs at the bottom of container A are taken out at the same time and water flows out.  What volume of water flows into container B? Pause if you want to try and solve it.  Okay, so the key thing to realize is that  each of these tubes here are the same. So the same amount of water is going to go out of them, right? So if there's 10 liters of water in  container A, then two are going to go out of each of these tubes, right? Because there's five of them and  they're all equal. So two is going to go through each of these tubes.  So if all of these tubes feed into this container over here, this container is going to have six liters of water, right?  And then that water is going to drain out through these two tubes over here. And since there's two of them and there's six liters of water going through them,  each one is going to get three. So, oops, a little glitch there.  This one is going to also get three, right? And then that means that we have three liters coming to container B through this tube,  two coming in through this one. So three plus two is five. So that means container B is going to get five liters, which is option C. So the answer to number six is C.

Video Summary

The video explains a problem involving water distribution between containers via multiple tubes. Container A, holding 10 liters of water, empties through five equal tubes, each releasing 2 liters. These tubes feed another container, which then releases 6 liters of water through two more tubes. Each of these secondary tubes transfers 3 liters of water. Consequently, container B receives a total of 5 liters—3 liters via one tube and 2 liters via the other—resulting in option C being the correct answer.
