In a certain code, HARYANA is written as 8197151, how is DELHI written in that code?

To solve this problem, we first need to understand how the code for HARYANA was created.

Step 1: Assign each letter of the alphabet a number. For example, A=1, B=2, C=3, ..., Z=26.

Step 2: Write down the corresponding numbers for HARYANA. H=8, A=1, R=18, Y=25, A=1, N=14, A=1. So, HARYANA is written as 819725141 in this code.

However, in the question, HARYANA is written as 8197151. This suggests that the code removes duplicate numbers. So, the second and third '1' from 819725141 are removed to get 8197151.

Step 3: Apply the same logic to DELHI. D=4, E=5, L=12, H=8, I=9. So, DELHI is written as 451289 in this code.

Step 4: Remove duplicates. In this case, there are no duplicates, so the code for DELHI remains 451289.
