Logical Riddle: Which Tank Will be Full First III (6 Tank Both Versions)
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?
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.
