Let's go

3rd

3 nd 4 will fill at d Same tym

4th will finish first

Tank 3 I think.

3rd one must full b4 leaking...

My answer is tank 3.

Tank 1 can't get filled up because it keeps losing water to tank 2.

Tank 2 can't get filled up because it keeps losing water to tank 3.

Tank 3 can only start filling up tank 4 once it gets sufficient volume/pressure to push water up that height to tank 4. So it's going to get filled up before tank 4 does.

Hope ayam not an olodo o. Oya clap for LadyF.

It's LadyF again

My problem with this kind of post is that the OP might not even know the real answer.. And he will keep people guessing until he got the answer or got really confused and the thread die because of too much debate by the association of ITKs.. Shalom

The third tank. If the third tank isn't full, the fourth tank can't fill up

yes it the 3rd one but this how u all fails examinations how will answer such question without backing it up with explanations
anyways.....
Solution:
the 3rd will first gets filled up because 1 and 2 doesn't need force to distribute water to next tanks but some amount of force is needed for number 3 to distribute to number 4 because of the way the pipe that connects both of them is, hence number 3 needs to first get filled up then weight of the quantity of water inside number 3 will be the force to make water passes to the upward pipe down to number 4 .... once number 3 reaches half filled up distribution will definitely begins to number 4 but the more the distribution the force needed from 3 to supply number 4 but at the end 3 definitely needs to be filled up before 4 then 2 and lastly 1 which brings us to =3,4,2,1

The more liquid in 3, the more force and momentum it gathers to forcefully push water into 4, Now how would that force come about? Container 3 will be filled up to gather in mass to bring about that force.
