If RAMON is written as 12345 and DINESH as 675849, then HAMAM will be written as

EXPLANATION

Correct Option (2)

The problem employs a direct letter-to-digit substitution coding scheme. The given information establishes the following mappings:

From RAMON = 12345:
- R = 1
- A = 2
- M = 3
- O = 4
- N = 5
From DINESH = 675849:
- D = 6
- I = 7
- N = 5 (consistent with the mapping from RAMON)
- E = 8
- S = 4
- H = 9

To determine the code for HAMAM, we extract the respective digit for each letter based on the established scheme:

H corresponds to 9.
A corresponds to 2.
M corresponds to 3.

Applying these substitutions to the word HAMAM sequentially:

H → 9
A → 2
M → 3
A → 2
M → 3

Therefore, HAMAM is coded as 92323.

Incorrect Options:

Options 1 (92233), 3 (93322), and 4 (93232) do not correspond to the unique letter-to-digit mapping derived from the provided coding examples. These options result from an incorrect application of the established substitution rules for the letters H, A, and M.
