Coding And Decoding - General Inteligence & Reasoning MCQ Questions and Answers

The middle letter remained unaltered in the code. Let us label the five letters before the middle letter as well as those after it, from 1 to 5. Then, the code contains the letters of each group in the order 5, 4, 1, 3, 2.
Thus, we have :
ESTABLISHED => BAETSLDEIHS
12345/12345 => 54132/54132

The letters of the word are written in the reverse order and in the group of letters so obtained, the first, third and fifth letters are each moved three steps forward while the second and fourth letters are each moved one step backward to get the code.

Each letter in the word is moved three steps forward to obtain the corresponding letter of the code.

The letters at the odd-numbered positions in the word are each moved two steps forward while those at the even-numbered positions are each moved three steps forward to obtain the corresponding letters of the code.

The first, third and fifth letters in the word are moved two, three and four steps forward respectively while the second, fourth and sixth letters are moved two, three and four steps backward respectively to obtain the corresponding letters of the code.

The last letter of the word remains unaltered in the code. The first six letters of the word are divided into two groups of three letters each and then, in each group, the last two letters are written in a reverse order.

Divide the word into six sets of two letters each and label these sets from 1 to 6. Then, the code contains these sets in the order 4, 3, 5, 2, 6, 1 with the letters of sets 3, 2, 1 written in a reverse order.
Thus, we have :
VI SH WA NA TH AN => NA AW TH HS AN IV.

The letters in the first half and second half of the word are written in the reverse order and then each letter of the group so obtained is moved one step forward to get the code. Thus, we have :
SILVER => SIL/VER => LIS/REV => MJT/SFW

The last four letters of the word are written in the reverse order, followed by the first three letters in the same order. In the group of letters so obtained, each letter except the middle letter is moved one step backward while the middle letter is moved one step forward to get the code.
Thus, we have :
SUPREME => SUP/REME => EMER/SUP => DLD/SRTO.

If in the word, a letter is the nth letter from the beginning of the English alphabet, then in the code the corresponding letter is the nth letter from the end.
