Q. In a certain language SIMPLE is written as ISPMEL and CHAPTER is written as HCPARET. Then LFWORE stands for which word?

Explanation:

Identify the pattern: reverse letters within fixed-size blocks from left to right—use 2-letter blocks; if the word ends with 3 letters (odd length), reverse that 3-letter block.
– SIMPLE (6): SI|MP|LE -> IS|PM|EL = ISPMEL
– CHAPTER (7): CH|AP|TER -> HC|PA|RET = HCPARET
To decode LFWORE (even length), swap each pair: LF|WO|RE -> FL|OW|ER = FLOWER.
Therefore, the word is FLOWER.
