Step-by-step Solution:

We are given that, ‘EXAMINATION’ = 56149512965 We can see that number places according to alphabetical order of E = 5, X = 24, A = 1, M = 13, I = 9, N = 14, T = 20, O = 15. We can see the pattern as
We can see the pattern as if the number > 9, then sum of the digit is assigned to that letter. If the number place < 9, the number place is assigned to that letter.
