This is the fortieth puzzle in Professor Layton and the Last Specter. To access this puzzle, you must talk to Badger. In order to solve this puzzle, you must figure out which extra pump is needed to fill the reservoir in exactly one day.


[edit] Hints

Hint One
    How much of the reservoir can each pump fill in one day?

    Is there any convenient way to add these amounts together?

Hint Two
    This puzzle can be solved by adding fractions together. If you dislike working with fractions, you can solve the problem by imagining the full reservoir has a certain amount of water in it.

Hint Three
    Pump A can fill the reservoir in three days. Therefore, it fills a third of the reservoir in one day. Pump B takes six days, so it will fill a sixth in one day. Pumps C and D also follow the same logic. You should be able to work out what remaining fraction is required by adding them together.

Super Hint
    Adding a third, a sixth, a tenth, and 1/15 gives exactly two thirds. Therefore, the reservoir requires a further third to be full. Which of the pumps is capable of providing that amount of water in one day?
