Coding-Decoding Questions and Answers

Q: If GOLD is coded as HOME, COME is coded as DONE and CORD is coded as DOSE, how would you code SONS?

Correct answer: TOOTConsonants advance one place and vowels stay as they are. GOLD gives H, O, M, E; COME gives D, O, N, E, the final E being a vowel and so unchanged; and CORD gives D, O, S, E. SONS therefore gives S→T, O unchanged, N→O, S→T, that is TOOT. Treating every letter alike would give TPOT, which is the first distractor.

Q: In a certain code, CLOUD is written as GTRKF. How is SIGHT written in that code?

Correct answer: WGJHVReverse the word, then apply an alternating shift of three forward and one back. CLOUD reversed is DUOLC, and D+3=G, U−1=T, O+3=R, L−1=K, C+3=F gives GTRKF. SIGHT reversed is THGIS, so T+3=W, H−1=G, G+3=J, I−1=H, S+3=V, giving WGJHV.

Q: In a certain code language the word NUMERICAL is written as LMUIREACN. How will the word PUBLISHED be written in thet language?

Correct answer: DBUSILEHPReverse the word, then exchange the second and third letters with the seventh and eighth. NUMERICAL reversed is LACIREMUN; swapping AC with MU gives LMUIREACN. PUBLISHED reversed is DEHSILBUP; swapping EH with BU gives DBUSILEHP. Both example and answer use exactly the same rearrangement, which is how the rule can be confirmed.

Q: In a certain code language the word DISTURB is written as DTWVUKF. How will the word FRANTIC be written in that language?

Correct answer: EKVPCTHReverse the word, then advance every letter by two. DISTURB reversed is BRUTSID, and adding two to each gives DTWVUKF. FRANTIC reversed is CITNARF, and adding two gives C→E, I→K, T→V, N→P, A→C, R→T, F→H, that is EKVPCTH.

.What is the code for ‘Thanks for the treat’?

A.Q13V P15H C2V R15V
B.Q12R P15H D3N S15S
C.P13V R14G C2W R15S
D.P13R Q15G D3V S15V
E.None of thes

Answer: A

Here each word is coded as follows:

The first word of the code for a corresponding word is the alphabet preceding 2 places to the last letter of the word in English Alphabetical order.

The last letter of the word for a corresponding word is the alphabet succeeding 2 places to the first word of the word in English Alphabetical order. The number in the middle of code is the absolute value of the difference of the position of the last alphabet for a word in English Alphabetical order and the number of alphabets in each corresponding word.

For example:

Trees: The first alphabet of the code is Q, which is preceding 2 places to S. The last alphabet of the code is V, which is succeeding 2 places to T.

The number is: 19(position of S) - 5(number of letters) = 14

Similarly,

Thanks for the treat is coded as ‘Q13V P15H C2V R15V’
