Correct Answer - Option 1 : 7629
Given: RAIL = 5181629 and SET = 7228 .
Consider, Z = 1, Y = 2, X = 3, ..... A = 26.
Here write equivalent positional value of each letter then reverse all code.
RAIL = R → 9, A → 26, I → 18, L → 15.
RAIL = 9261815
After reversing code of RAIL = 5181629
SET = S → 8,
E → 22, T → 7.
SET = 8227.
After reversing code of SET = 7228
So, RAT = R → 9, A → 26, T → 7.
RAT = 9267
After reversing code of RAT = 7629
Hence,
code for RAT is 7629.
