# Coding and Decoding Questions and Answers – Set 10

This set of Logical Reasoning Questions and Answers (MCQs) focuses on “Coding and Decoding – Set 10”.

1. In a certain code “SUGAR” is written as “TWJEW”. How is “SALTY” written in that code?
a) SRLEP
b) DKALE
c) TCOXD
d) UDQAN

Explanation: Here, every letter of the word moves +n from its position where n is position of alphabet in the word.
i.e. for SUGAR, S+1→T, U+2→W, G+3→J, A+4→E, R+5→W.
Similarly, for SALTY, S+1→T, A+2→C, L+3→O, T+4→X, Y+5→D.

2. In a certain code “GLOBAL” is written as “DILYXI”. How is “UNIVERSE” written in that code?
a) BCJWCKUA
b) RKFSBOPB
c) SHXLHCJC
d) CJCWPNCV

Explanation: Here, each letter moves -3 from its original position.
i.e. for “GLOBAL” the code is DILYXI.
Similarly, for “UNIVERSE” the code is RKFSBOPB.

3. In a certain code “CLOUD” is written as “ZILRA”. How “MEMORY” is written in that code?
a) JBJLOV
b) SPURGV
c) NJVGAR
d) EOQGAV

Explanation: Here, each letter moves +3 from its original position.
i.e. for “CLOUD” →C→Z, L→I, O→L, U→R, D→A.
Similarly, for “MEMORY” the code is JBJLOV.

4. In a certain code “564” means “all the best”, “736” means “best of luck” and “423” means “all is luck”. Which of the following is the word for digit “6”?
a) all
b) best
c) luck
d) the

Explanation: Here, in the first and second statement, the common code number is ‘6’ and common word is ‘best’. In the second and third statement the common code number is ‘3’ and common word is ‘luck’. In first and third statement, the common code number is ‘4’ and common word is ‘all’.
Therefore, 3→luck, 4→all, 6→best.
This gives, 2→is, 5→the, 7→of.

5. In a certain code “MAGNET” is written as “MAGnEt”. How is “FERROUS” written in that code?
a) fErrOUS
b) FeRRouS
c) fErRoUS
d) FeRrOuS

Explanation: Here, according to the positions of the alphabets, odd position alphabets are written in capital letters whereas, even position alphabets are written in small letters.

6. If the letters of the word “EVEREST” are arranged alphabetically, then which letter would be 2nd in the right from the second letter of word?
a) T
b) E
c) R
d) V

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

7. In a certain code “PARAGRAPH” is written as “PRAGAARHP”. How can “SUMMARY” be written in that code?
a) SMUAMYR
b) SUAMMRY
c) SMAMUYR
d) SAUMMRY

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

8. In a certain code “ENTHALPY” is written as “50.5”. Then how can “ENTROPY” be written in that code?
a) 48.5
b) 31.8
c) 56.5
d) 52.4

Explanation: Here, the positional values of alphabets are added and then divided by 2.
i.e. ENTHALPY→5 + 14 + 20 + 8 + 1 + 12 + 16 + 25 = 101÷2 = 50.5.
Similarly, for ENTROPY→ 5 + 14 + 20 + 18 + 15 + 16 + 25 = 113÷2 = 56.5.

9. In a certain code “GR4VI7Y” is written as “MX10BO13E”. How is “F0RC3” written in that code?
a) F1D8R
b) X8KV3
c) L6XI9
d) FO46E

Explanation: Here, each alphabet and number moves +6 from its original position.
i.e. G→M, R→X, 4→10, V→B, I→O, 7→13, Y→E.
Similarly, for F0RC3 the code is L6XI9.

10. If ‘white’ is called ‘yellow’, ‘yellow’ is called ‘blue’, ‘blue’ is called ‘red’, ‘red’ is called ‘black’, ‘black’ is called ‘violet’, ‘violet’ is called ‘green’, ‘green’ is called ‘magenta’, and ‘magenta’ is called ‘white’ then what would be the colour if we mix yellow and magenta together?
a) Red
b) Green
c) Black
d) Yellow

Explanation: Here, the colour when we mix yellow and magenta will be red and it is given that ‘red’ is called ‘black’.
