In a code language, 'TEMPER' is written as 'ETPMRE'. How will 'CHROME' be written as in that language?

Let's study how the letters are rearranged in 'TEMPER' to form 'ETPMRE':
Divide the word into pairs of two letters:
Scribd

TE → ET (reversed)

MP → PM (reversed)

ER → RE (reversed)

Combining them gives ETPMRE.

Now apply this adjacent pair-reversal logic to 'CHROME':

CH → HC

RO → OR

ME → EM

Combining the results gives HCOREM.
