This set of Logical Reasoning Questions and Answers (MCQs) focuses on “Coding and Decoding – Set 2”.
1. In a certain code “CANDLE” is written as “CBNELF”. How is “STICK” written in that code?
a) SRLFE
b) MDKAl
c) SUIDK
d) UDLPQ
View Answer
Explanation: Here, after first letter every alternate letter of the word moves +1 from its position.
i.e. for CANDLE, A→B, D→E, E→F.
Similarly, for STICK, T→U, C→D.
Hence, the answer is SUIDK.
2. In a certain code “ZEBRA” is written as “ZQADY”. How is “TIGER” written in that code?
a) BWKXU
b) QDFHS
c) SHXAL
d) GQWPJ
View Answer
Explanation: Here, reverse the words and move -1 from its original position.
i.e. for “ZEBRA” the reversed word is ARBEZ and the code is ZQADY.
Similarly, for “TIGER” the reversed word is REGIT and the code is QDFHS.
Hence, the answer is QDFHS.
3. In a certain code “MOBILE” is written as “NPCJMF”. How “MESSAGE” is written in that code?
a) NFTTBHF
b) HRAOSCV
c) NWJJEFL
d) ELDSSAP
View Answer
Explanation: Here, each letter moves +1 from its original position.
i.e. for “MOBILE” M→N, O→P, B→C, I→J, L→M, E→F.
Similarly, for “MESSAGE” the code is NFTTBHF.
Hence, the answer is NFTTBHF.
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 “very”?
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 5.
5. In a certain code “BASKET” is written as “BaskeT”. How is “PACKET” written in that code?
a) pAcKeT
b) PaCkET
c) PacKeT
d) PackeT
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 PacKeT.
6. If the letters of the word “POSITION” are arranged alphabetically, then which letter would be farthest from the second letter of word?
a) O
b) S
c) T
d) P
View Answer
Explanation: Here, when arranged alphabetically the word is IINOOPST.
Hence, the answer is T.
7. In a certain code “PICTURE” is written as “9267315”. How can “CURE” be written in that code?
a) 7316
b) 6137
c) 6315
d) 2615
View Answer
Explanation: Here, from PICTURE P→9, I→2, C→6, T→7, U→3, R→1, E→5.
Therefore CURE→6315
Hence, the answer is 6315.
8. In a certain code “CAT” is written as “12”. Then how can “STAR” be written in that code?
a) 58
b) 36
c) 47
d) 29
View Answer
Explanation: Here, the positional values of alphabets are added and then divided by 2.
i.e. C→3 + A→1 + T→20 = 24÷2 = 12.
Similarly, for STAR→ 19+20+1+18 = 58÷2 = 29
Hence, the answer is 29.
9. In a certain code “M0B1L3” is written as “P3E4O6”. How is “1NT3RNE7” written in that code?
a) 4HFID8E8
b) 5R9X8KV8
c) 4QW6UQH10
d) 5KF2E4R4
View Answer
Explanation: Here, each alphabet and number moves +3 from its original position.
i.e. M→P, 0→3, B→E, 1→4, L→O, 3→6.
Similarly, for 1NT3RNE7 the code is 4QW6UQH10.
Hence, the answer is 4QW6UQH10
10. If in the English alphabet, every alternate letter from D onwards is written in capital letters while others are written in small, then how will the 3rd day from Sunday will be coded?
a) WEdNesDaY
b) weDNesDay
c) FrIDay
d) THuRsDay
View Answer
Explanation: Here, the capital letters are D, F, H, J, L, N, P, R, T, V, X, Z. The third day from sunday will be wednesday and code will be weDNesDay.
Hence, the answer is weDNesDay.
