This set of Logical Reasoning Questions and Answers (MCQs) focuses on “Coding and Decoding – Set 3”.
1. In a certain code “POSTAL” is written as “PPSUAM”. How is “JOURNAL” written in that code?
a) SRLFEDR
b) JDKDSAL
c) JPUSNBL
d) UDLPQKA
View Answer
Explanation: Here, after first letter every alternate letter of the word moves +1 from its position.
i.e. for POSTAL, O→P, T→U, L→M.
Similarly, for JOURNAL, O→P, R→S, A→B.
Hence, the answer is JPUSNBL.
2. In a certain code “HORSE” is written as “DRQNG”. How is “DONKEY” written in that code?
a) BWKXUA
b) XDJMNC
c) SHXALC
d) GQWPNC
View Answer
Explanation: Here, reverse the words and move -1 from its original position.
i.e. for “HORSE” the reversed word is ESROH and the code is DRQNG.
Similarly, for “DONKEY” the reversed word is YEKNOD and the code is XDJMNC.
Hence, the answer is XDJMNC.
3. In a certain code “SPARK” is written as “TQBSL”. How “FIRE” is written in that code?
a) GJSF
b) HRCF
c) NJEL
d) ESAP
View Answer
Explanation: Here, each letter moves +1 from its original position.
i.e. for “SPARK” S→T, P→Q, A→B, R→S, K→L.
Similarly, for “FIRE” the code is GJSF.
Hence, the answer is GJSF.
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 “hard”?
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 “HYDROGEN” is written as “HyDRogeN”. How is “OXYGEN” written in that code?
a) OxYgEn
b) oXyGeN
c) oXygeN
d) OxyGen
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 oXygeN.
6. If the letters of the word “POSITION” are arranged alphabetically, then which letter would be 2nd in the right 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 O.
7. In a certain code “DELHI” is written as “92675” and “BOMBAY” is written as “431408”. How can “MADRAS” be written in that code?
a) 13241295
b) 61374
c) 109704
d) 261
View Answer
Explanation: Here, from DELHI AND BOMBAY we can predict that M→1, A→0, D→9. And no other option has 6 digits to code MADRAS.
Therefore MADRAS→109704
Hence, the answer is 109704.
8. In a certain code “DOG” is written as “13”. Then how can “HEAR” 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. D→4 + O→15 + G→7 = 26÷2 = 13.
Similarly, for HEAR→ 8+5+1+18 = 32÷2 = 16
Hence, the answer is 16.
9. In a certain code “FL4M3” is written as “IO7P6”. How is “L1GH7” written in that code?
a) F1D8E
b) X8KV8
c) O4JK10
d) 2E4R4
View Answer
Explanation: Here, each alphabet and number moves +3 from its original position.
i.e. F→I, L→O, 4→7, M→P, 3→6.
Similarly, for L1GH7 the code is O4JK10.
Hence, the answer is O4JK10
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 SATURDAY will be coded?
a) TuesDay
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 saturday will be tuesday and code will be TuesDay.
Hence, the answer is TuesDay.
