In a certain code, WANT is written as 4715 and COPE is written as 2863. How is NOTE written in that code?

The letter-to-digit direct coding scheme is as follows:
From **WANT $\to$ 4715**:

* W = 4
* A = 7
* N = 1
* T = 5

From **COPE $\to$ 2863**:

* C = 2
* O = 8
* P = 6
* E = 3

Using these individual direct codes for NOTE:

* N = 1
* O = 8
* T = 5
* E = 3

Therefore, NOTE is coded as 1853.
