Numerical equivalent of D is 4, E is 5, G is 7 and P is 16 which is formed by adding 4 + 5 + 7 = 16
Numerical equivalent of H is 8, A is 1, D is 4 and M is 13 which is formed by adding 8 + 1 + 4 = 13
Numerical equivalent of S is 19, B is 2, K is 11 and F is 6 which is formed by adding 19 + 2 + 11 = 32 = 32 - 26 = 6
(whenever sum goes to more that 26 than again add digit and take that sum)
But, Numerical equivalent of T is 20, F is 6, K is 11 and L is 12 which is not formed by adding 20 + 6 + 11 = 37 = 37 - 26 = 11
So, TFKL is the odd one out.
