AMPEROLB
BMPELROB
CMPERLOB ✓ Correct
DMEPLROB
Correct answer: (C) MPERLOB — The code for PROBLEM is MPERLOB, so the answer is MPERLOB.
Explanation
★The code for PROBLEM is MPERLOB, so the answer is MPERLOB.
★The code is formed by re-ordering the letters of the word by position.
★The new order takes the letters in the positions seventh, first, sixth, second, fifth, third, fourth.
★For TROUBLE this gives E, T, L, R, B, O, U, that is ETLRBOU.
★For PROBLEM the seventh letter is M, then P, then E, then R.
★Then come L, O and B, giving M, P, E, R, L, O, B.
★So the code is MPERLOB.
