This is the seventy-first puzzle you will encounter in Professor Layton and the Diabolical Box. To access this puzzle, you must talk to Ilyana. In order to solve this puzzle, you must determine the age of the girl.


[edit] Hints

Hint One
    Start by figuring out how old the girl was back when the boy was as old as the girl is now.

    What relationship does the girl's past age have with the boy's current age?

Hint Two
    Maybe you already picked up on this, but if you double the girl's age from back when the boy was the girl's current age, you should get the boy's current age of 20.

Hint Three
    Using the facts in Hint Two, you can ascertain that the girl was 10 back when the boy was the girl's current age. Since then, X years have passed, the boy has become 20, and the girl has become her current age. If you can find a number of years that, when added to 10 and subtracted from 20, yield the same age, you're very close to finding the girl's current age.

    Now what could X be?

[edit] When Failed

Too bad!

Decide upon a number from which to begin your reasoning, and take it from there.

[edit] When Completed


A careful read of the puzzle reveals that when the boy was the girl's current age, her age was half of the boy's current age. The boy's current age is 20, and half of that is 10, so the girl must have been 10 back then.

Once you know this and factor in the other hints, it's obvious that the girl must be 15 now.

[edit] Solution


The girl's current age is 15.

[edit] Progress
