21. In a certain code language, ‘RSMLPDFN’ is written as ‘LLEGFWXE’. What is the code for ‘XZBHQNTV’ in that code language? [RRB NTPC 21/01/2021 (Morning)]

Correct Answer: (a) RSTYKGLM
Solution:

22. If SUDDEN is coded as RVCEDO, then what will GROWTH be coded as? RRB NTPC 21/01/2021 (Evening)

Correct Answer: (d) FSNXSI
Solution:

S - 1 = R,
U + 1 = V, D - 1 = C, D + 1 = E, E - 1 = D,
N + 1 = O
Similarly, GROWTH is written as FSNXSI.

23. If def is coded as 222120 and qtv is coded as 964, then which of the given options follows the same code? [RRB NTPC 21/01/2021 (Evening)]

Correct Answer: (c) hik = 181715
Solution:

Using (opposite face value - 1)
d opposite w - 23 - 1 = 22
e opposite v - 22 - 1 = 21
F opposite u - 21 - 1 = 20
Similarly,
hik is written as 181715

24. In a certain language, ‘Delhi is capital’ is written as ‘753 852 159’, ‘Ram lives in Delhi’ is written as,‘153 253 159 157’ and ‘Ram is teacher’ is written as ‘753 157 954’. What is “capital” coded as? [RRB NTPC 21/01/2021 (Evening)]

Correct Answer: (c) 852
Solution:

Delhi is capital’ - ‘753 852 159’ ---- (i)
Ram lives in Delhi’ - ‘153 253 159 157’
----------(ii)
Ram is teacher’ - ‘753 157 954’ ----------(iii)
Delhi is common in (i) and (ii) so, delhi = 159
“Is” common in (i) and (iii) so, is = 753
Hence, capital = 852

25. If STYLE is 81, ACE is 9 and BOLD is 33, then what will be the difference between SMART and GOLD if these are coded in the same manner? [RRB NTPC 21/01/2021 (Evening)]

Correct Answer: (d) 33
Solution:

Sum of the place value of the algebraic digit.
STYLE = 19 + 20 + 25 + 12 + 5 = 81
So that GOLD = 7 + 15 + 12 + 4 = 38 and
SMART = 19 + 13 + 1 + 18 + 20 = 71
Hence, difference between the SMART and GOLD = 71 - 38 = 33

26. If LIGHT is coded as KHFQS, then what will SHORT be coded as ? [RRB NTPC 21/01/2021 (Evening)]

Correct Answer: (c) RGNQS
Solution:

L - 1 = K, I - 1 = H, G - 1 = F,
H - 1 = G, T - 1 = S
So that SHORT is written as RGNQS

27. In a certain code language, ‘JUNIOR’ is written as ‘6’, ‘LABOURER’ is written as ‘8’. What is the code for ‘JOSEPHINE’ in that code language? [RRB NTPC 21/01/2021 (Evening)]

Correct Answer: (b) 9
Solution:

Number of digits
In “JUNIOR” number of digits = 6
Similarly “JOSEPHINE” has 9 digits.

28. If BASE = 27, then what is COLLECTION? [RRB NTPC 21/01/2021 (Evening)]

Correct Answer: (a) 108
Solution:

B + A + S + E = 2 + 1 + 19 + 5 = 27
Similarly, COLLECTION is written as 108

29. If A = 26 and T = 7, then AUTHENTIC = ? [RRB NTPC 22/01/2021 (Morning)]

Correct Answer: (a) 266719221371824
Solution:

A → 26, T → 7
Logic → using opposite face value
AUTHENTIC → 266719221371824

30. In a certain code language, HUNGER is written as UHATRE. How will SWIMMING be written as in that language ? [RRB NTPC 22/01/2021 (Morning)]

Correct Answer: (b) FJVVZVAT
Solution:
