This mystery is coded in binary code. For those of you who are not familiar with this code, here's a quick introduction which will be enough to help you out. Binary code is made out of zero and one digits. This is eventually how all computing and all letters/numbers/symbols comes down to, 0's and 1's.
The following table will show you the values you need to know in binary, it is quite simple since we just need the values 0-9 for coordinates.
0 = 0000
1 = 0001
2 = 0010
3 = 0011
4 = 0100
5 = 0101
6 = 0110
7 = 0111
8 = 1000
9 = 1001
Now for the puzzle:
Each country represents either 1 or 0
A = China, India, Vietnam, Thailand
B = USA, Canada, Mexico, Costa Rica
C = Germany, Italy, Spain, Holland
D = Ethiopia, Kenya, Zambia, Nigeria
E = Cuba, Iceland, Fiji, Philippines
F = Brazil, Argentina, Peru, Chile
Cache location is at:
N 32 4.ABC , E 34 49.DEF
Too difficult? Ok how about this -Â
Israel = 0, Cyprus = 1
France = 0, England = 1
South Korea = 0, Japan = 1
Much easier now, right?
So what is left to do? decode the 0's and 1's into the digits, and find where the cache is
