Indian Institute of Foreign Trade 2011 Solved Paper

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 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.
In GOVERNMENT, G = 7, O = 1+5 = 6, V = 2+2 = 4, E = 5, R = 1+8 = 9, N = 1+4 = 5, M = 1+3 = 4, E = 5, N = 1+4 = 5, T = 2+0 = 2
Therefore, the code for 'GOVERNMENT' = 7645954552. Hence, option A is the correct answer.
