Given: Basic is written as DDULE.

Logic: Alternate addition of 2 and 3 to the positional values

Hence, NHCGGU is the correct answer . Adobe Scan 23-Feb-2025

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.
Accordingly,M will become O
O will become M
B will become E
I will become F
L will become P
E will become A

The first letter of the word is replaced by a set of two letters - one following it and the other preceding it - in the code. The remaining letters of the word are each moved one step backward to obtain the remaining letters of the code, in order.

Hence,

MORE = NLNQD

Explanation Option (d) is correct. The middle letter remains unaltered in the code. Let us label the five letter before the middle letter as well as those after it, from 1 to 5. Then the code contain the letters of each group in the order 5, 4, 1, 3, 2. E S T A B L I S H E D→ B A E T S L D E I H S1 2 3 4 5 1 2 3 4 5

The correct option is b EOJDJEFM

- There are 8 letters in the word.
- The coded word can be obtained by taking the immediately following letters of word, expect the first and the last letters of the given word but in the reverse order. That means, in the coded form the first and the last letters have been interchanged while the remaining letters are coded by taking their immediate next letters in the reverse order.

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
COVALENT- COVA / LENT- AVOC / TNEL
→
BWPD / UOFM
and
FORM- FO / RM- OF / MR
→
PG / NS

In the same way,
SILVER– SIL / VER– LIS / REV
→
MJT / SFW
Hence, the correct answer is MJTSFW.

Given, the word COMPATIBLE is coded as BQNPDDKAHS.
First, we need to find the pattern among the coded letters with the original word. COMPATIBLE contains ten letters and its corresponding coded word BQNPDDKAHS also contains the same number of letters. So, each letter has its own code.
Logic: The word COMPATIBLE is to be divided into two equal parts and both parts are to be reversed separately. Then, each letter which are in the first part is shifted ahead to one place, and each letter in the second part is shifted one place back to its original place.
COMPATIBLE => COMPA/TIBLE => APMOC/ELBIT => BQNPD/DKAHS => BQNPDDKAHS

Similarly, for the word STABILISED,
STABILISED => STABI/LISED => IBATS/DESIL => JCBUT/CDRHK => JCBUTCDRHK
Hence, the coded word for STABILISED is JCBUTCDRHK.
Hence, "JCBUTCDRHK" is the correct answer.

The correct option is d Adobe Scan 23-Feb-2025 (1)BHSSFKHM
The letters in first half and second half of the word are written in the reverse order and then in the group of letters so obtained the 1st, 3rd ,5th and 7th letters are each move one step forward while the 2nd, 4th, 6th and 8th letters are each moved one step backward to get the code.

The correct option is c 8251896
Since, in CALICUT, C is coded as 8, A is coded as 2, L as 5, I as 1, U as 9, T as 6. So, code for CALICUT IS 8251896.
Option c is correct.

Letters at the odd places have been coded one step forward(i.e.C will be coded as D), while letters at the even places have been coded one step backwards as per their positions(i.e. A will be coded as Z), in the alphabets from A-Z.
Therefore, CALCUTTA will be coded as DZMBVSUZ.

The first letter B is coded as Z means that it moves backward with 1 letter similarly R is coded as P, O is coded as M,W is coded as U, and N is coded as L. So VIOLET is coded as TGMJCR.
