41. If DO is coded as 60 and SO is coded as 285, [RRB NTPC 08/01/2021 (Morning)]

then which of the following will be the code for RED?

Correct Answer: (a) 360
Solution:

DO → 4 × 15 = 60
SO → 19 × 15 = 285
RED → 18 × 5 × 4 = 360

42. In a certain code language, MINIATURE is written as 495912395. [RRB NTPC 08/01/2021 (Morning)]

How will PRIVATE be written as in that language?

Correct Answer: (c) 7994125
Solution:

Code for MINIATURE:
M = 13 → 1 + 3 = 4, I = 9, N = 14 → 1 + 4 = 5 → I = 9, A = 1, T = 20 → 2 + 0 = 2,
U = 21 → 2 + 1 = 3, R = 18 → 1 + 8 = 9, E = 5
Similarly,
P = 16 → 1 + 6 = 7,
R = 18 → 1 + 8 = 9,
I = 9
V = 22 → 2 + 2 = 4, A = 1
T = 20 → 2 + 0 = 2, E = 5
The code for PRIVATE = 7994125

43. If A is equal to 1, M is equal to 13 and R is equal to 18, how would you write MISSION? [RRB NTPC 08/01/2021 (Evening)]

Correct Answer: (b) 139191991514
Solution:

Position value of letters are written.
MISSION = 139191991514

44. In a code language, if KARAN is written as 45, then how will ARUN be written as in that language? [RRB NTPC 08/01/2021 (Evening)]

Correct Answer: (a) 54
Solution:

KARAN = 11 + 1 + 18 + 1 + 14 = 45
ARUN = 1 + 18 + 21 + 14 = 54

45. In a code language, LAST is written as 1234 and BOOK is written as 5667. [RRB NTPC 08/01/2021 (Evening)]

How will TOAST be written as in that language?

Correct Answer: (c) 46234
Solution:

From two examples, it can be observed that the code for T = 4,
O = 6, A = 2,
S = 3. So TOAST can be written as 46234.

46. In a code language, FORWARD is written as 1234536 and WATER is written as 45783. [RRB NTPC 08/01/2021 (Evening)]

How will RETARD be written as in that language?

Correct Answer: (c) 387536
Solution:

From two examples it can be observed that the code for R = 3, E = 8, T = 7, A = 5 and D = 6.
So, the code for RETARD = 387536

47. In a code language, if RAMAN is written as 47, then how will ARJUN be written as in that language? [RRB NTPC 08/01/2021 (Evening)]

Correct Answer: (c) 64
Solution:

Sum of alphabetic position of number.
RAMAN = 18 + 1 + 13 + 1 + 14 = 47
Similarly,
ARJUN = 1 + 18 + 10 + 21 + 14 = 64

48. If SUN is coded as 54, then how will MOON be coded as? [RRB NTPC 09/01/2021 (Morning)]

Correct Answer: (b) 57
Solution:

SUN is coded as
54 [19 + 21 + 14 = 54]
Similarly, MOON will be coded as
57 [13 + 15 + 15 + 14 = 57]

49. Which of the following numbers stands for ‘be’ in that language? [RRB NTPC 09/01/2021 (Evening)]

In a certain code language –
‘123’ means ‘good to taste’
‘456’ means ‘see you soon’
‘789’ means ‘be right back’

Correct Answer: (c) 7
Solution:

From the given coding we observe that no word is common in any two lines so each digit will be code of word given in that sentence only
Code for ‘be’ = 7

50. If A is equal to 1, S is equal to 19, and G is equal to 7, how would you spell ‘MASSAGE’? [RRB NTPC 09/01/2021 (Evening)]

Correct Answer: (a) 1311919175
Solution:

Coded as per their alphabetical positions so MASSAGE will be coded as 1311919175
