1. no 6 will be filled first

2. My coffee cup.
I mean, I’ve been looking at that picture for ages, and the drop hasn’t moved at all, so it’s not going to fill anything.

3. 8??? THERE IS NO WATER FEED TO IT.

4. It is definitely 8. You see the way to cup 3 is blocked as is the way to cup 6. Since the levels of the the spouts on each cup won’t fill the cup before the water flows out of the cup and the hole in cup 7 is at the bottom it will be cup 8

5. # 8, assuming (like Griff Nelson) that the flow of water from the faucet is slower than the water flow out of the drain lines to tanks #2 and #7, and the hole in the bottom of tank #7

6. I think 5

7. 4th tank

8. According to my calculations… ,none of them will be FILLED first. Now think about it.

9. Number 6

10. Looks like #8 to me

• None of them will filled

11. The 8th cup. I thought at first it was the 4th but realized that was incorrect after further details came to light. I didn’t see the blocks.

12. It depends on the water flow. If it’s flowing so heavily that the pipe to 2 cannot drain off enough, then 1 will fill the fastest. On the other hand, if the flow is slow enough, the water will flow into 2, then to 7, and finally into 8, which would fill first. 3, 4, 5 & 6 are all blocked off, and no water can flow into them. The only way 6 could fill would be for 2 to overflow, which would make 2 full first, but, as earlier stated, if it’s flowing that heavily, 1 would fill first. So, 1 if heavy flow, 8 if a slow enough flow.
Period.

13. 8 IS THE ONLY ONE THAT WILL FILL UP. ALL OF THE OTHERS ARE BLOCKED OR HAVE A LEAK.

14. No 8 will only fill fully as 1 bottom hole is blocked so 3 4 5 cannot be filled 2 bottom hole is blocked so 6 cannot be filled and 7 has a hole in the bottom to fill 8

15. Tank 8 will be the first and only tank to fill.

16. Number 1 will fill up first, number seven has a hole on bottom!

• Cup5 fills up first

17. because it will definitely fill up faster than 7 and nothing will get through to 4 and 6 because of that wall in the middle of the pipe blocking all the water

• btw my answer is 8

18. 8th tank will be filled first

• None of the tank will be filled up
Look carefully at the figure
