# Coding and Decoding Questions and Answers – Set 3

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

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.

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

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.

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

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.

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

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 “HYDROGEN” is written as “HyDRogeN”. How is “OXYGEN” written in that code?
a) OxYgEn
b) oXyGeN
c) oXygeN
d) OxyGen

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 “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

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

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

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.

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

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

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

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.

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

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.
