Thanks for visiting! Let’s get down to cracking the code. But first, the problem statement:

The first code is 63AC and it is transformed to FC19. The trick is that the numbers 6 and 3 get transformed to the 6th and 3rd letters of the alphabet series. And therefore, we have FC in place of 63.

Next, for AC, the trick is to note that the position of A in the alphabet series is 1 and that of C is 3. 19 is obtained from AC by squaring 1 and 3 respectively.

Now this can be verified using the second code transformation – 91EG is transformed to IA2549. Clearly, the 9th letter is I and the 1st letter is A. Also, E’s position in the series is 5 and G’s position is 7. Therefore, we have the squares of 5 and 7, i.e. 25 and 49.

Using this logic, the code 85DM is transformed into HE16169
