This set of Logical Reasoning Questions and Answers (MCQs) focuses on “Coding and Decoding – Set 8”.
1. In a certain code “PETROL” is written as “QGWVTR”. How is “DIESEL” written in that code?
a) SRLFEP
b) JDKALE
c) EKHWJR
d) UDQKAN
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 PETROL, P+1→Q, E+2→G, T+3→W, R+4→V, O+5→T, L+6→R.
Similarly, for DIESEL, D+1→E, I+2→K, E+3→H, S+4→W, E+5→J, L+6→R.
Hence, the answer is EKHWJR.
2. In a certain code “INTEREST” is written as “GLRCPCQR”. How is “PASSION” written in that code?
a) BWKXUAA
b) NYQQGML
c) SHXXHLH
d) GWPPNCV
View Answer
Explanation: Here, each letter moves -2 from its original position.
i.e. for “INTEREST” the code is GLRCPCQR.
Similarly, for “PASSION” the code is NYQQGML.
Hence, the answer is NYQQGML.
3. In a certain code “INTEL” is written as “KPVGN”. How “ALTER” is written in that code?
a) CNVGT
b) SPUSR
c) NJEVP
d) ESPTO
View Answer
Explanation: Here, each letter moves +2 from its original position.
i.e. for “INTEL” →I→K, N→P, T→V, E→G, L→N.
Similarly, for “ALTER” the code is CNVGT.
Hence, the answer is CNVGT.
4. In a certain code “564” means “all the best”, “736” means “best of luck” and “423” means “all is luck”. Which of the following is the code for “luck”?
a) 6
b) 4
c) 3
d) 7
View Answer
Explanation: Here, in the first and second statement, the common code number is ‘6’ and common word is ‘best’. In the second and third statement the common code number is ‘3’ and common word is ‘luck’. In first and third statement, the common code number is ‘4’ and common word is ‘all’.
Therefore, 3→luck, 4→all, 6→best.
This gives, 2→is, 5→the, 7→of.
Hence the answer is 3.
5. In a certain code “HELIUM” is written as “hElIUM”. How is “ARGON” written in that code?
a) ArGOn
b) aRGoN
c) argON
d) ARgOn
View Answer
Explanation: Here, according to the positions of the alphabets, odd position alphabets are written in capital letters whereas, even position alphabets are written in small letters.
Hence, the answer is ArGOn.
6. If the letters of the word “ALPHABET” are arranged alphabetically, then which letter would be 2nd in the right from the third letter of word?
a) A
b) E
c) H
d) T
View Answer
Explanation: Here, when arranged alphabetically the word is AABEHLPT.
Hence, the answer is H.
7. In a certain code “CONDUCTOR” is written as “CNOUDTCRO”. How can “INSULATOR” be written in that code?
a) ISNLUTARO
b) INLSUTAOR
c) INSLUAROT
d) ISLNRATOU
View Answer
Explanation: Here, after first letter of the word the remaining letters are swapped with its adjacent letter.
Therefore for INSULATOR the code is ISNLUTARO.
Hence, the answer is ISNLUTARO.
8. In a certain code “HALE” is written as “13”. Then how can “MALL” be written in that code?
a) 14
b) 11
c) 17
d) 19
View Answer
Explanation: Here, the positional values of alphabets are added and then divided by 2.
i.e. H→5 + A→1 + L→12 + E→5 = 26÷2 = 13.
Similarly, for MALL→ 13+1+12+12 = 38÷2 = 19
Hence, the answer is 19.
9. In a certain code “CL34R” is written as “FO67U”. How is “ER45E” written in that code?
a) F1D8R
b) X8KVS
c) HU78H
d) E4R4N
View Answer
Explanation: Here, each alphabet and number moves +3 times from its original position.
i.e. C→F, L→O, 3→6, 4→7, R→U.
Similarly, for ER45E the code is HU78H.
Hence, the answer is HU78H.
10. If ‘white’ is called ‘yellow’, ‘yellow’ is called ‘blue’, ‘blue’ is called ‘red’, ‘red’ is called ‘black’, ‘black’ is called ‘violet’ and ‘violet’ is called ‘green’, then what would be the colour of evening sky?
a) Red
b) Green
c) Black
d) Yellow
View Answer
Explanation: Here, the colour of evening sky is red and it is given that ‘red’ is called ‘black’.
Hence, the answer is Black.
