A easy Myst where the final location is at N 48° 24.164′ E 10° 51.889′.

📖 The Story

It was in the year 2000 when an inconspicuous container was hidden somewhere in this world –
and thus began an entire movement: geocaching.

25 years have passed since then.
Containers were hidden, containers were found.
Some cachers came, others disappeared.
Some coordinates now lead only to nowhere – overgrown, forgotten, lost.

But 25 years later, in 2025, the community celebrated a special anniversary:
A quarter century of adventure, technology, nature – and numbers.

🧩 The Task

Your Mission:

Find the mysterious number GC to locate the final hiding place.

It is:

• two-digit

• begins with a 2 and ends with a 5

• is greater than 24 and less than 26

• odd divisible by 1, 5, and 25

• and a quarter of 100

📍 Calculate the final

Once you've found the number GC, plug it into the formula:

N 48° 24.164 + (GC − 25)
E 10° 51.889 − (GC − 25)

Substituting this gives (let's use 25 as an example):

N 48° 24.164 + (25 − 25) = N 48° 24.164′
E 10° 51.889 − (25 − 25) = E 10° 51.889′
