Coding – Decoding (SSC MTS 2021 Tier 1)

11. In a certain code language, ‘TANK’ is coded as ‘4’ and ‘PIR’ is coded as ‘3’. How will ‘FREIGHT’ be coded in that language? [S.S.C MTS 06/07/2022 (Afternoon)]

(a) 7
(b) 9
(c) 6
(d) 5

Correct Answer: (a) 7

Solution:Each word is coded by the number of letters in that word.
TANK = 4, PIR = 3
Similarly,

In FREIGHT, number of letters are 7. Hence, option (a) is the correct answer.

12. R 4 is related to P 2 in a certain way. In the same way, F 7 is related to D 5. To which of the following is Z 8 related following the same logic? [S.S.C MTS 06/07/2022 (Afternoon)]

(a) X 6
(b) Y 6
(c) X 7
(d) Y 7

Correct Answer: (a) X 6

Solution:R4 ⇒ (R - 2) = P, (4 - 2) = 2 → P 2
F7 ⇒ (F - 2) = D, (7 - 2) = 5 → D 5
Similarly,

Z 8 ⇒ (Z - 2) = X, (8 - 2) = 6 → X 6
Hence, the required answer is X 6.

13. In a certain code language, ‘Numbers are even’ is coded as ‘5 3 +’ and ‘Odd factors are multiples’ is coded as ‘+ 7 6 @’. What can be the code for ‘even’ in that code language? [S.S.C MTS 06/07/2022 (Evening)]

(a) 6
(b) +
(c) 5 or 3
(d) 7

Correct Answer: (c) 5 or 3

Solution:From "Numbers are even" and "Odd factors are multiples", we get "are" = "#".
So, the code for "even" will be either "5" or "3". Hence, option (c) is the correct answer.

14. In a certain code language, if dress is called comb, comb is called hair dryer, hair dryer is called lipstick, lipstick is called sandal, and sandal is called jewellery, then what is used to colour the lips? [S.S.C MTS 06/07/2022 (Evening)]

(a) Jewellery
(b) Comb
(c) Hair dryer
(d) Sandal

Correct Answer: (d) Sandal

Solution:Usually lipstick is used to colour the lips and here lipstick is called sandal. Hence, option (d) is the correct answer.

15. In a certain code language, ‘random boys talk’ is written as ‘8 3 P’, ‘talk too much girls’ is written as ‘3 4 2 6’. How will ‘talk’ be written in that language? [S.S.C MTS 07/07/2022 (Morning)]

(a) 3
(b) P
(c) 2
(d) 8

Correct Answer: (a) 3

Solution:From "random boys talk" and "talk too much girls", we get "talk" = 3
Hence, option (a) is the correct answer.

16. In a certain code language, ‘TOPICS’ is written as ‘QAGONS’ and ‘GREATH’ is written as ‘FRYDQF’. How will ‘BANDEF’ be written in that language? [S.S.C MTS 08/07/2022 (Morning)]

(a) DCCMZA
(b) DCBMZA
(c) DCBMYA
(d) DCBNYA

Correct Answer: (b) DCBMZA

Solution:

17. In a certain code language, ‘nu vu du’ is written as ‘Time and Money’, ‘hu du ru’ is written as ‘Manage Money Judiciously’ and ‘tu vu lu’ is written as ‘Save More Time’. What is the code for ‘Save More Money’ in that code language? [S.S.C MTS 08/07/2022 (Afternoon)]

(a) du nu lu
(b) nu tu du
(c) tu lu du
(d) tu vu du

Correct Answer: (c) tu lu du

Solution:

Hence, "Save More Money" → "tu lu du".

18. In a certain code language, '591' means ‘sky is blue’, '256' means ‘sea is deep’ and '609' means ‘sea looks blue’. Which number is the code for ‘blue’ in that language? [S.S.C MTS 11/07/2022 (Afternoon)]

(a) 0
(b) 9
(c) 1
(d) 5

Correct Answer: (b) 9

Solution:From "sky is blue" and "sea looks blue", we get blue → "9".
Hence, option (b) is the correct answer.

19. D 2 is related to H 6 in a certain way. In the same way, L 1 is related to P 15. To which of the following is T 18 related following the same logic? [S.S.C MTS 12/07/2022 (Morning)]

(a) Z 22
(b) X 22
(c) Y 22
(d) W 22

Correct Answer: (b) X 22

Solution:D 2 ⇒ {(D + 4) = H and (2 + 4) = 6} → H 6
L 1 ⇒ {(L + 4) = P and (1 + 14) = 15} → P 15
Similarly,

T 18 ⇒ {(T + 4) = X and (4 + 18) = 22} → X 22

Hence, option (b) is the correct answer.

20. In a certain code language, ‘ANAEMIA’ is written as ‘AOAENIA’ and ‘AQUEOUS’ is written as ‘ARUEOUST’. How will ‘EUGENIA’ be written in that language? [S.S.C MTS 12/07/2022 (Morning)]

(a) EUHEOJA
(b) FVGFJNB
(c) EUHEOIA
(d) FUGFNJB

Correct Answer: (c) EUHEOIA

Solution:Each consonant is replaced by a letter at +1 position while each vowel is kept as it is.
