If HONGKONG is coded as 42309230 and DELHI is coded as 85641, how can LONDON be coded?

HONGKONG → 42309230
DELHI → 85641

LONDON → ?

Logic: Focus only on common letters.

From DELHI → 85641:

D → 8

E → 5

L → 6

H → 4

I → 1

So from here:

From HONGKONG → 42309230:

Look at repeating letters:

O appears 2 times → digits 2, 9, 2 (pattern gives 2/3 type)

N appears 2 times → consistent digit 3 type pattern

Approx. mapping (option):

Now LONDON:

L O N D O N
→ 6 2 3 8 2 3
