This set of Logical Reasoning Questions and Answers (MCQs) focuses on “Coding and Decoding – Set 4”.
1. In a certain code “STAMP” is written as “TVDQU”. How is “FLAME” written in that code?
a) SRLFE
b) JDKAL
c) GNDQJ
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 STAMP, S+1→T, T+2→V, A+3→D, M+4→Q, P→U.
Similarly, for FLAME, F+1→G, L+2→N, A+3→D, M+4→Q, E+5→J.
Hence, the answer is GNDQJ.
2. In a certain code “PIEGON” is written as “OHDFNM”. How is “OSTRICH” written in that code?
a) BWKXUAF
b) NRSQHBG
c) SHXALCE
d) GQWPNCV
View Answer
Explanation: Here, each letter moves -1 from its original position.
i.e. for “PIEGON” the code is OHDFNM.
Similarly, for “OSTRICH” the code is NRSQHBG.
Hence, the answer is NRSQHBG.
3. In a certain code “CIRCUIT” is written as “DJSDVJU”. How “BOARD” is written in that code?
a) CPBSE
b) HRCFK
c) NJELV
d) ESAPT
View Answer
Explanation: Here, each letter moves +1 from its original position.
i.e. for “CIRCUIT” C→D, I→J, R→S, C→D, U→V, I→J, T→U.
Similarly, for “BOARD” the code is CPBSE.
Hence, the answer is CPBSE.
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 “work”?
a) 6
b) 4
c) 5
d) 3
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 6.
5. In a certain code “NITROGEN” is written as “NiTRogeN”. How is “CARBON” written in that code?
a) CarBon
b) cARBoN
c) caRBoN
d) CaRbON
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 caRBoN.
6. If the letters of the word “CAPTAIN” are arranged alphabetically, then which letter would be 2nd in the right from the third letter of word?
a) A
b) N
c) T
d) P
View Answer
Explanation: Here, when arranged alphabetically the word is AACINPT.
Hence, the answer is N.
7. In a certain code “COLONEL” is written as “CLONOLE”. How can “BRIGADIER” be written in that code?
a) RBIGDARE
b) BRIAGERDA
c) BIRAGIDRE
d) GARIBDEIR
View Answer
Explanation: Here, after first letter of the word the remaining letters are swapped with its adjacent letter.
Therefore for BRIGADIER the code is BIRAGIDRE
Hence, the answer is BIRAGIDRE.
8. In a certain code “FISH” is written as “21”. Then how can “SWIM” be written in that code?
a) 58
b) 32
c) 27
d) 16
View Answer
Explanation: Here, the positional values of alphabets are added and then divided by 2.
i.e. F→6 + I→9 + S→19 + H→8 = 42÷2 = 21.
Similarly, for SWIM→ 19+23+9+13 = 64÷2 = 32
Hence, the answer is 32.
9. In a certain code “M4J0R” is written as “P7M3U”. How is “V1C7ORY” written in that code?
a) F1D8EMR
b) X8KV8SJ
c) Y4F10RUB
d) 2E4R4NY
View Answer
Explanation: Here, each alphabet and number moves +3 from its original position.
i.e. M→P, 4→7, J→M, 0→3, R→U.
Similarly, for V1C7ORY the code is Y4F10RUB.
Hence, the answer is Y4F10RUB.
10. If in the English alphabet, every alternate letter from B onwards is written in capital letters while others are written in small, then how will the 2ND day from Wednesday will be coded?
a) TuesDay
b) weDNesDay
c) FRiDay
d) THuRsDay
View Answer
Explanation: Here, the capital letters are B, D, F, H, J, L, N, P, R, T, V, X, Z. The third day from Wednesday will be Friday and code will be FRiDay.
Hence, the answer is FRiDay.
