I received 1 more of the “Which-tank-will-fill-first” riddles in 2 versions.
I am including both the versions in this riddle along with answers.
Looking at the picture below, which tank will fill first?
If you get the correct answer, share it with your friends on WhatsApp, Facebook and other social networking sites.
Tank 2 will fill first in version 1
Tank 5 will fill first in version 2.
In version 1 you will be tempted the think that 3 will be the first one but 3 will only start filling once the water starts to come into 4, which will happen only after 2 is full.
In version 2 since the connection between 5 & 2 are blocked, water will not flow beyond tank 5 so the fifth tank will fill first.
