Question
If in a certain code, 'POT' is written as ATOP and 'TRAP' is written as APART, then how is 'ARENA' written in that code?
Options
a
AARENA
b
AANREA
c
AANEAR
dAnswer
AANERA
Explanation
Analyze the structural letter movements between the source words and their codes:
`P O T` (3 letters) \rightarrow becomes `A T O P`. The letter string is reversed (`P-O-T` \rightarrow `T-O-P`) and a prefix letter `A` is added.
`T R A P` (4 letters) \rightarrow becomes `A P A R T`. The letter string is reversed (`T-R-A-P` \rightarrow `P-A-R-T`) and a prefix letter `A` is added .
The cipher operation reverses the entire string and prefixes it with the character 'A'. Apply this exact rule to `ARENA`:
1Reverse the string: `A R E N A` \rightarrow `A N E R A`.
2Add the prefix 'A': `A` + `ANERA` = `AANERA`.
Break layout shifting codes down into basic structural moves—like complete string reversals or fixed letter additions—before generating the target sequence.
Answer: (d).
