This set of Logical Reasoning Questions and Answers (MCQs) focuses on “Coding and Decoding – Set 5”.
1. In a certain code “INTEL” is written as “JPWIQ”. How is “CABLE” written in that code?
a) SRLFE
b) JDKAL
c) DCEPJ
d) UDQKA
View Answer
Explanation: Here, every letter of the word moves +n from its position where n is position of alphabet in the word.
i.e. for INTEL, I+1→J, N+2→P, T+3→W, E+4→I, L→Q.
Similarly, for CABLE, C+1→D, A+2→C, B+3→E, L+4→P, E+5→J.
Hence, the answer is DCEPJ.
2. In a certain code “CONTROL” is written as “BNMSQNK”. How is “INSERT” written in that code?
a) BWKXUA
b) HMRDQS
c) SHXALC
d) GWPNCV
View Answer
Explanation: Here, each letter moves -1 from its original position.
i.e. for “CONTROL” the code is BNMSQNK.
Similarly, for “INSERT” the code is HMRDQS.
Hence, the answer is HMRDQS.
3. In a certain code “ROBOT” is written as “SPCPU”. How “BRAIN” is written in that code?
a) CSBJO
b) SPUPS
c) NJELV
d) ESAPT
View Answer
Explanation: Here, each letter moves +1 from its original position.
i.e. for “ROBOT” R→S, O→P, B→C, O→P, T→U.
Similarly, for “BRAIN” the code is CSBJO.
Hence, the answer is CSBJO.
4. In a certain code “564” means “study very hard”, “736” means “hard work pays” and “423” means “study and work”. Which of the following is the code for “pays”?
a) 6
b) 4
c) 5
d) 7
View Answer
Explanation: Here, in the first and second statement, the common code number is ‘6’ and common word is ‘hard’. In the second and third statement the common code number is ‘3’ and common word is ‘work’. In first and third statement, the common code number is ‘4’ and common word is ‘study’.
Therefore, 3→work, 4→study, 6→hard.
This gives, 2→and, 5→very, 7→pays.
Hence the answer is 7.
5. In a certain code “FLOURINE” is written as “FLouRiNe”. How is “GASOLINE” written in that code?
a) GaSOlINe
b) gAsOlInE
c) gasoLiNE
d) GAsOliNE
View Answer
Explanation: Here, according to the positions of the alphabets, odd position alphabets are written in small letters whereas, even position alphabets are written in capital letters.
Hence, the answer is gasoLiNE.
6. If the letters of the word “COLONEL” are arranged alphabetically, then which letter would be 2nd in the right from the third letter of word?
a) L
b) N
c) O
d) C
View Answer
Explanation: Here, when arranged alphabetically the word is CELLNOO.
Hence, the answer is N.
7. In a certain code “DUTIES” is written as “DTUEIS”. How can “SYMBOL” be written in that code?
a) SYBOML
b) YSBNLO
c) SMYOBL
d) SBMYLO
View Answer
Explanation: Here, after first letter of the word the remaining letters are swapped with its adjacent letter.
Therefore for SYMBOL the code is SMYOBL
Hence, the answer is SMYOBL.
8. In a certain code “WOMAN” is written as “33”. Then how can “MAN” be written in that code?
a) 14
b) 32
c) 27
d) 16
View Answer
Explanation: Here, the positional values of alphabets are added and then divided by 2.
i.e. W→23 + O→15 + M→13 + A→1 + N→14 = 66÷2 = 33.
Similarly, for MAN→ 13+1+14 = 28÷2 = 14
Hence, the answer is 14.
9. In a certain code “AN5W3R” is written as “CP7Y5T”. How is “QU3ST1ON” written in that code?
a) F1D8EMR
b) X8KV8SJ
c) SW5UV3QP
d) 2E4R4NY
View Answer
Explanation: Here, each alphabet and number moves +2 from its original position.
i.e. A→C, N→P, 5→7, W→Y, 3→5, R→T.
Similarly, for QU3ST1ON the code is SW5UV3QP.
Hence, the answer is SW5UV3QP.
10.If ‘white’ is called ‘yellow’, ‘yellow’ is called ‘blue’, ‘blue’ is called ‘red’, ‘red’ is called ‘black’ and ‘black’ is called ‘violet’, then what would be the colour of human blood?
a) Red
b) Violet
c) Black
d) Yellow
View Answer
Explanation: Here, the colour of human blood is red and it is given that ‘red’ is called ‘black’.
Hence, the answer is Black.
