#20 Caesar cipher
Solution

You can get from 3 to 47 using the Caesar
cipher – the method that Julius Caesar used
to encrypt messages, by shifting letters a
fixed number of places up the alphabet.

If you shift the word THREE by four places,
you get XLVII, which is 47 in Roman
numerals.

Coincidentally, if you convert the letters of
the alphabet into numbers, A=1, B=2, and
so on, then C=3, and C+A+E+S+A+R = 47.
