Which Tank Will Fill Up First – Blockages at D & H
A
B
C
ANSWER:
The answer is F. Here’s how:
As soon as the level of water in bucket A reaches the pipe feeding B, it will start flowing and filling up B, and then logically C will start filling up. Now C has two pipes that will drain the water out of it. As shown in the above pic, the pipe feeding D is blocked, and none of the buckets it feeds will fill up (i.e., D, E & G).
So water will logically start filling up J. Now J again has two pipes draining water out of it. Now, here most people think, the bottommost pipe will drain bucket J, but the pipe draining out of it feeds at the top of the bucket. According to simple fluid dynamics, I wouldn’t start filling up unless and until J fills up to the same level as the pipe feeding into I. But before J fills up to the top, the pipe feeding L will drain water out of it, which will make sure J doesn’t fill up to the brim. From there on, the answer is simple. H is blocked and the bucket F will fill up first.
So again F filled up first. So that settles it that the answer is F both logically and scientifically. If you answered F, you are correct.
