Coding – Decoding (SSC CHSL 2020 Tier 1)

Total Questions: 17

1. In a certain code language, 'SEMANTIC' is coded as 14485293. How will 'PRACTICE' be coded in that language? [SSC CHSL 12/04/2021 (Afternoon)]

Correct Answer: (b) 79832934
Note:

Logic: Sum of the alphabetical positioning of the consonant and the reverse alphabetical positioning of the vowels.
So, PRACTICE → 16 - 18 - 26 - 3 - 20 - 18 - 3 - 22
On the sum of their digits 7 - 9 - 8 - 3 - 8 - 2 - 9 - 3 - 4.

2. In a certain code language, 'PROFANE' is written as KOLCZKV. How will 'DISOBEY' be written in that language? [SSC CHSL 13/04/2021 (Morning)]

Correct Answer: (d) WFHLYBB
Note:

Logic: (i) Alphabets at odd places are coded with the opposite alphabet (ii) Alphabets at even places are decreasing by 3.
DISOBEY → (D ↔ W, S ↔ H, B ↔ Y, Y ↔ B) and (I - 3 = F, O - 3 = L, E - 3 = B)
So, the final code for DISOBEY is WFHLYBB.

3. In a certain code language, 'ROCKET' is written as BNQSJD. How will 'NOTICE' be written in that language? [SSC CHSL 13/04/2021 (Afternoon)]

Correct Answer: (a) SNMDBH
Note:

Logic: Divide the number into two half of 3 letters each and then reverse them and subtract one from each letter.
NOTICE is NOT - ICE after reversing TON - ECI and after subtracting one from it.

SNM - DBH.

 

4. In a certain code language, 'REASON' is coded as 51 and 'BAKE' is coded as 47. How will 'MARRY' be coded in that language? [SSC CHSL 16/04/2021 (Morning)]

Correct Answer: (d) 35
Note:

Logic: sum of reverse alphabetical positioning of consonants and alphabetical positioning of vowels.
So, MARRY = 14 + 1 + 9 + 9 + 2 = 35.

5. In a certain code language, 'LIABILITY' is coded as 950759513 and 'PROCTOR' is coded as 8642146. How will 'PICTORIAL' be coded in that language? [SSC CHSL 16/04/2021 (Afternoon)]

Correct Answer: (b) 852146509
Note:

Logic: Letters are directly coded as their corresponding number.
LIABILITY → 950759513
PROCTOR → 8642146
PICTORIAL → 852146509

6. In a certain code language, 'INHALE' is coded as 110 and 'DELAY' is coded as 86. How will 'IGNORE' be coded in that language? [SSC CHSL 19/04/2021 (Afternoon)]

Correct Answer: (c) 91
Note:

Logic: sum of reverse alphabetical positioning - numbers of vowels.
In, IGNORE → 18 + 20 + 13 + 12 + 9 + 22 = 94 - 3 (three vowels in IGNORE) = 91.

7. If in a code language, 'ROHAN' is coded as 3136 and 'SHYAM' is coded as 4356, then how will you code 'RAM'? [SSC CHSL 19/04/2021 (Evening)]

Correct Answer: (d) 1024
Note:

Logic: square of sum of alphabetical position.
RAM = 18 + 1 + 13 = 32² = 1024.

8. In a certain code language, 'BACK' is written as YEXP and 'MIXTURE' is written as NOCGAII. How will 'FROGS' be written in that language? [SSC CHSL 04/08/2021 (Afternoon)]

Correct Answer: (d) UIUTH
Note:

Logic: (i) For consonants: The opposite letter is used.
(ii) For vowels: The next vowel is used.
In the word FROGS,
The consonants are,
F → U, R → I, G → T, S → H
And the only one vowel is O → U
So, FROGS will be coded as UIUTH.

9. In a certain code language, 'CANDIDATE' is coded as 846292417 and 'ACTION' is coded as 481936. How will 'DICTATION' be coded in that language? [SSC CHSL 04/08/2021 (Evening)]

Correct Answer: (d) 298141936
Note:

Logic: Here direct coding is used.
Eg: C → 8, A → 4, N → 6, D → 2, I → 9, O → 2, A → 4, T → 1, E → 7.
A → 4, C → 8, T → 1, I → 9, O → 3, N → 6
So, the code for DICTATION will be 298141936.

10. In a certain code language, 'PROUD' is written as WVJPK. How will 'GUILTY' be written in that language? [SSC CHSL 04/08/2021 (Evening)]

Correct Answer: (c) NPDSAF
Note:

Logic: (i) For consonants: ‘+7’ code is used.
(ii) For vowels: ‘-5’ code is used.
In the word "GUILTY"
The code for the consonants are
G + 7 = N, L + 7 = S, T + 7 = A, Y + 7 = F
The code for the vowels are
U - 5 = P, I - 5 = D
The final code for the word “GUILTY” will be NPDSAF.
