# Coding and Decoding Questions and Answers – Set 4

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

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.

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

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.

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

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.

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

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.

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

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.

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

Explanation: Here, when arranged alphabetically the word is AACINPT.

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

Explanation: Here, after first letter of the word the remaining letters are swapped with its adjacent letter.
Therefore for BRIGADIER the code 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

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

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

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.

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

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.
