Practice MCQ Questions and Answer on Coding and Decoding
41.
If TOUR is written in a certain code as 1234, CLEAR as 56784 and SPARE as 90847, what will be the 5th digit for SCULPTURE in the same code ?
(A) 3
(B) 4
(C) 6
(D) 0
Solution:
By, comparing letters and digit, we get T = 1 O = 2 U = 3 R = 4 C = 5 L = 6 E = 7 A = 8 S = 9 and P = 0 As the 5th letter is SCULPTURE is P and '0' is used for P, therefore, 5th digit is the required code which is '0'.
42.
If BOX is coded as CDPQYZ, what will be the last two letters of word in the same code for HERO ?
(A) N ,M
(B) M ,N
(C) Q ,P
(D) P ,Q
Solution:
Last two letters of the word CDPQYZ are next two letters of the word BOX. In the same way, the last two letters of HERO if coded will be P, Q.
43.
In a certain code, ROAD is written as URDG. How is SWAN written in that code?
(A) VXDQ
(B) VZDQ
(C) VZCP
(D) UXDQ
Solution:
Each letter in the word is moved three steps forward to obtain the corresponding letter of the code.
44.
In a certain language, SIGHT is written as FVTUG. How is REVEAL written in the same language?
(A) YNRIRE
(B) DQHQMX
(C) FSJSOZ
(D) ERIRNY
Solution:
Each letter in the word is moved thirteen steps forward to obtain the corresponding letter of the code.
45.
If SUMMER is coded RUNNER, the code for WINTER is
(A) SUITER
(B) VIOUER
(C) WALKER
(D) SUFFER
Solution:
SUMMER = RUNNER In the given code, second, fifth and sixth letters are same. The first letter of the word (S → R) is moved one step backward, while the two middle letters (M → N and M → N) each moved one step forward to obtain the corresponding letters of the code. So, WINTER = VIOUER.
46.
In a certain code language, BOARD is written as EQBNC. How will the word CLIMB be written in that language?
(A) CLJKD
(B) DKJLF
(C) DNHMB
(D) FNJRO
Solution:
The letters of the word are written in a reverse order and the group of letters so obtained, the first, third and fifth letters are each moved one step forward while the second and fourth letters are each moved one step backward to get the code.
47.
In a certain code language, OMNIPRESENT is written as QJONPTSMDRD. How is CREDIBILITY written in that code?
(A) DSFEJDDXSHKH
(B) JEFSDCXSHKH
(C) JEFSDDXSHKH
(D) JEFSDDZUJMJ
Solution:
Keeping the middle letter as it is, the first five and the last five letters of the word are written in the reverse order. In the group of letters so obtained, the first five letters are each moved one step forward, the middle letter is moved two steps forward and the last five letters are each moved one step backward to get the code. Thus, we have : CREDI/B/ILITY => IDERC/B/YTILI => JEFSD/D/XSHKH
48.
If HARD is coded s 1357 and SOFT is coded as 2468, what do the figures 21448 stand for ?
(A) SHOOP
(B) SHOOL
(C) SCOOL
(D) SHOOT
Solution:
H = 1 A = 3 R = 5 D = 7 S = 2 O = 4 F = 6 T = 8. Hence, 21448 = SHOOT.
49.
In a certain system of coding, the word STATEMENT is written as TNEMETATS. In the same system of coding, what should be the code for the word POLITICAL?
(A) LACITILOP
(B) LCATILIOP
(C) OPILITACL
(D) None of these
Solution:
The letters of the given word are written in a reverse order to obtain the code. Reversing the order of letters in POLITICAL, we get LACITILOP.
50.
In a certain code, cloud is written as GTRKF. How is SIGHT written in that code?
(A) UGHHT
(B) UHJFW
(C) WFJGV
(D) WGJHV
Solution:
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.
