6 large pipes, on their own, can drain the reservoir in 12 hours.

3 large pipes and 9 small pipes, at the same time, can drain the reservoir in 8 hours.

How long will 5 small pipes, on their own, take to drain the reservoir?

Hint

How many large pipes are required to drain the reservoir in 24 hours?

Answer

21 hours and 36 minutes.

Reasoning

Looking at the first clue:

in 12 hours, 6 large pipes can drain 1 reservoir

in 24 hours, 6 large pipes can drain 2 reservoirs

(*) in 24 hours, 3 large pipes can drain 1 reservoir

Looking at the second clue:

in 8 hours, 3 large + 9 small pipes can drain 1 reservoir

in 24 hours, 3 large + 9 small pipes can drain 3 reservoirs

But, by (*), we know that in those 24 hours, 3 large pipes can drain 1 of those reservoirs.

Therefore, the other 2 reservoirs can be drained by the small pipes on their own:

in 24 hours, 9 small pipes can drain 2 reservoirs

in 24 hours, 1 small pipe can drain 2/9 reservoirs

multiply the hours by 9:

in 216 hours, 1 small pipe can drain 2 reservoirs

in 216 hours, 5 small pipes can drain 10 reservoirs

divide the hours by 10:

in 21.6 hours, 5 small pipes can drain 1 reservoir

21.6 hours = 21 hours and 36 minutes.
