Type 1 : Letter Coding

In these questions, the real letters in a word are replaced by certain other letters according to a specific rule to form the code. The candidate is required to detect the common rule and answer the questions accordingly.

Examples

  1. If in a certain language MYSTIFY is coded as NZTUJGZ, how is NEMESIS coded inthat language?

(a)   MDLHRDR

(b)   OFNFTJT

(c)   ODNHTDR

(d)   PGOKUGU.

Solution

Each letter in MYSTIFY is moved one step forward to obtain the corresponding letter of the code.

M Y S T I F Y

+ 1 ↓

N Z T U J G Z

So, in NEMESIS, N will be coded as O, E as F, M as N and so on. Thus, code becomes OFNFTJT. Hence, answer is (b).

  1. If TAP is coded as SZO, then how is FREEZE coded?

(a)   EQDFYG

(b)   ESDFYF

(c)   GQFDYF

(d)   EQDDYD.

Solution

Each letter in the word TAP is moved one step backward to obtain the corresponding letter of the code.

S Z O

-1 ↑

T A P

Thus, in freeze, F will be coded as E, R as Q, E as D and Z as Y. So the code becomes

EQDDYD.

Hence, the answer is (d).

  1. In a certain code SIKKIM is written as THLJJL. How is TRAINING written in that code?

(a)   SQBHOHOH

(b)   UQBHOHOF

(c)   UQBJOHHO

(d)   UQBJOHOH.

Solution

The letters in the word SIKKIM are moved alternately one step forward and one step backward to obtain the letters of the code.

-1

H -1 J -1 L

↑↑↑

S I K K I M

+ 1↓ -1↓ -1↓

T L J

In TRAINING, T will be coded as U, R as Q, A as B, I as H and so on. Thus, the code becomes UQBHOHOF.

Hence, answer is (b)

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

(a)   APTTREM

(b)   PTAETNR

(c)   OTAETNR

(d)   OTAETRN.

Solution

To obtain the code, the first letter of the word MENTION is removed one step backward and the remaining letters are reversed in order, taking two at a time,

M E N T I O N

-1↓

L

Thus, PATTERN becomes OTAETNR.

Hence, answer is (c).

  1. In a certain code FORGE is written as FPTJI. How is CULPRIT written in that code?

(a)   CSJNPGR

(b)   CVMQSTU

(c)   CVNSVNZ

(d)   CXOSULN.

Solution

The first letter in FORGE remains as it is and the second, third, fourth and fifth letters are respectively moved one, two, three and four steps forward to obtain the corresponding letters of the code.
