If '123' is coded as '456', what is the code for '789'?

If '123' is coded as '456', what is the code for '789'?

Step 1: Look at the first code '123' and its corresponding code '456'.
Step 2: Compare each digit in '123' with the digit in '456'.
Step 3: Notice that '1' becomes '4', '2' becomes '5', and '3' becomes '6'.
Step 4: See that each digit in '123' is increased by 3 to get '456'.
Step 5: Now apply the same rule to '789'.
Step 6: Increase '7' by 3 to get '10', but since we only want a single digit, we take '0' (if we consider only the last digit).
Step 7: Increase '8' by 3 to get '11', take '1'.
Step 8: Increase '9' by 3 to get '12', take '2'.
Step 9: Combine the results to get the final code for '789'.
