Let A = 1, B = 2, ..., Y = 25, Z = 26.

Find the sum, mod 26, of the values of the letters of each word, and then convert the sum back into its letter value.

For example

ACRE: A = 1, C = 3, R = 18, E = 5. 1 + 3 + 18 + 5 = 27 = 1 (mod 26). 1 -> A

BRAG: B = 2, R = 18, A = 1, G = 7. 2 + 18 + 1 + 7 = 28 = 2 (mod 26). 2 -> B

And for the solution:

XRAY: X = 24, R = 18, A = 1, Y = 25. 24 + 18 + 1 + 25 = 68 = 16 (mod 26). 16 -> P
