In a certain code language, 'FIND' is written as 'CLFB' and 'HOW' is written as 'VME'. How will 'WILL' be written in that language?

Let's analyze how words are transformed by looking at alphabetical positional values from right to left (reversing the letter sequence):
For **FIND $\to$ CLFB**:

* Reverse the word letters first: $\text{D, N, I, F}$
* Subtract increasing values sequentially ($-1,-2,-3,-4$):
* $\text{D}(4)-1=\text{C}(3)$
* $\text{N}(14)-2=\text{L}(12)$
* $\text{I}(9)-3=\text{F}(6)$
* $\text{F}(6)-4=\text{B}(2)$
This yields the code CLFB.

For **HOW $\to$ VME**:

* Reverse the word letters: $\text{W, O, H}$
* Subtract increasing values sequentially ($-1,-2,-3$):
* $\text{W}(23)-1=\text{V}(22)$
* $\text{O}(15)-2=\text{M}(13)$
* $\text{H}(8)-3=\text{E}(5)$
This yields the code VME.

Applying the exact same coding rule to WILL:

* Reverse the letters: $\text{L, L, I, W}$
* Subtract step-wise values ($-1,-2,-3,-4$):
* $\text{L}(12)-1=\text{K}(11)$
* $\text{L}(12)-2=\text{J}(10)$
* $\text{I}(9)-3=\text{F}(6)$
* $\text{W}(23)-4=\text{S}(19)$

Hence, 'WILL' is written as KJFS.
