41. In a certain code language, TARA is coded as 1600. How will NARA be coded as in that language? [RRB NTPC 02/03/2021 (Evening)]

Correct Answer: (a) 1156
Solution:

T + A + R + A = 20 + 1 + 18 + 1 = 40
then, (40)² = 1600
Similarly,
N + A + R + A = 14 + 1 + 18 + 1
= (34)² = 1156

42. In a certain code language, MANGOE is coded as 131415. How will EAGLE be coded as in that language? [RRB NTPC 02/03/2021 (Evening)]

Correct Answer: (a) 575
Solution:

43. In a certain code language, ‘PQRS’ is written as ‘HIJK’. How will ‘XYZA’ be written as in the same coding language? [RRB NTPC 03/03/2021 (Morning)]

Correct Answer: (d) PQRS
Solution:

44. In a certain code language, ‘LANGUAGE’ is written as ‘HWJCQWCA’. How will ‘CODE’ be written as in the same code language? [RRB NTPC 03/03/2021 (Morning)]

Correct Answer: (b) YKZA
Solution:

45. In a certain code language, ‘cockroach is insect’ is written as ‘pq mr lo’, ‘insect are species’ is written as ‘fl mr sn’, is cockroach species’ is written as ‘lo pq fl’. What is the code for ‘species insect’ in that code language? [RRB NTPC 03/03/2021 (Evening)]

Correct Answer: (a) fl mr
Solution:

(i) ‘cockroach is insect’ – ‘pq mr lo’
(ii) ‘insect are species’ – ‘fl mr sn’
(iii) ‘is cockroach species’ – ‘lo pq fl’
From (i) and (ii) → insect = mr
And (ii) and (iii) → species = fl
So that, ‘species insect’ is written as “fl mr”

46. In a certain language, ‘MOLECULES’ is written as ‘SLEUECLMO’. How will ‘TRANSDUCTION’ be written in that language? [RRB NTPC 03/03/2021 (Evening)]

47. In a certain language, RAIN is written as 4678 and WET is written as 135. How will ENTER be written as in that language? [RRB NTPC 03/03/2021 (Evening)]

Correct Answer: (b) 38534
Solution:

From the given examples we can observe that the code for E = 3, N = 8, T = 5, R = 4
So the code for ENTER = 38534

48. In a certain coding language, ‘CUMIN’ is written as ‘AVKJL’ and ‘GUEST’ is written as ‘EVCTR’. How will ‘ALIEN’ be written in that language? [RRB NTPC 03/03/2021 (Evening)]

Correct Answer: (b) YMGFL
Solution:

C - 2 = A, U + 1 = V, M - 2 = K,
I + 1 = J, N - 2 = L
Similarly, ALIEN
A - 2 = Y, L + 1 = M, I - 2 = G,
E + 1 = F, N - 2 = L
YMGFL

49. In a certain code language, AGE is written as 13 and SEX is written as 48. How will COME be written as in that language? [RRB NTPC 04/03/2021 (Morning)]

Correct Answer: (c) 36
Solution:

Sum of the position values of alphabets.
COME = 3 + 15 + 13 + 5 = 36

50. In a certain code language, MAY is written as 123, RULE is written as 4567 and FUND is written as 8590. How will LAND be written as in that language? [RRB NTPC 04/03/2021 (Morning)]

Correct Answer: (d) 6290
Solution:

From the given examples we can observe that the code for L = 6, A = 2, N = 9 and D = 0
The code for LAND = 6290
