An encryption machine uses a formula to encrypt words, by taking each letter and changing it to the letter that is just before it in the alphabet. If the letter is ‘a’, it changes it to ‘z’. If you put the word STAR into the machine, what would the output be?
A) TARS
B) RSZQ
C) TUBS
D) RSTA

Respuesta :

The output of the word STAR is RSZQ

How to determine the output?

The encryption rule is given as:

Change a letter to the previous letter

This means that:

S -> R

T -> S

A -> Z

R -> Q

So, we have:

STAR -> RSZQ

Hence, the output of the word STAR is RSZQ
