In letter coding type of questions, the real alphabets in a word are replaced be certain other alphabets according to a specific rule to form its code. The candidate is required to detect the common rule and answer the questions accordingly.

In a certain code, MENTION is written as LNEITNO.
How is PATTERN written in that code ?

Option:
A. APTTREM
B. PTAETNR
C. OTAETNR
D. OTAETRN
E. None of these
Answer: C . OTAETNR

Justification:

Clearly, to obtain the code, the first letter of the word MENTION is moved one step backward and the remaining letters are reversed in order, taking two at a time.
(M → L), (E ↔ N), (T ↔ I), (O ↔ N)
So, in  PATTERN, P will be coded as O and the sequence of the remaining letters in the code would be TAETNR.
Thus, the code becomes OTAETNR.
Hence, the answer is (c).
