In a certain code language, TROUBLE is written as ETLRBOU. How will PROBLEM be written in that language?

AMPEROLB

BMPELROB

CMPERLOB ✓ Correct

DMEPLROB

Correct answer: (C) MPERLOB

Explanation

PROBLEM becomes MPERLOB.

The coded letters take the original positions 7,1,6,2,5,3,4.

TROUBLE (1T 2R 3O 4U 5B 6L 7E) rearranges to E T L R B O U = ETLRBOU.

PROBLEM = 1P 2R 3O 4B 5L 6E 7M.

Picking positions 7,1,6,2,5,3,4: M P E R L O B.

So PROBLEM = MPERLOB.
