We have the following letters and their frequencies

Solving (1): 1.

From the alphabets listed above:

,              

So, the 3:2 can be H : any of the alphabets. For this solution, we use:

Solving (2)

This is the inverse of (1) solved above.

So 2 : 3 is:

Solving (3)

From the alphabets listed above:

Any selected alphabet will represent 2 : 2

So, we have:

or O : any of C, A and E

Solving (4):.

The total of all alphabet in the given word is: 13.

So,

Solving (5):

The total of all alphabet in the given word is: 13.

So,
