Question

Consider LET + LEE = ALL where every letter represents a unique digit from 0 to 9, find out

(A+L+L) if E=5.

a) L

b) LE

c) E

d) A

e) TL​

Answer 1

Answer:

L=1 E=5 T=6

So,

1 5 6

1 5 5 (+)

-------

3 1 1

-------

A=3 So, 3+1+1=5 ==> E

Answer 2

Option c) E

LET + LEE = ALL where every letter represents a unique digit from 0 to 9

(A+L+L) if E=5.

Solution.

L=1 E=5 T=6

So,

   1 5 6

(+)1 5 5

-------

3 1 1

-------

A=3

3+1+1=5 => E

• The study of various mathematical models of communication channels utilising a range of mathematical techniques is the focus of the applied mathematics field known as the theory of alphabetical coding. The best-studied codes are block or uniform codes, in which the length of the coded combinations is fixed.
• Any word, letter, or sentence can be encoded or decoded using a predetermined pattern or code based on a set of rules. This process is known as coding and decoding.
• Information is encoded and decoded using a variety of rules or patterns so that only the intended recipient can understand it.
