41. Select the option that is related to the fifth number in the same way as the second number is related to the first number and the fourth number is related to the third number. [Group-D 20/09/2022 (Afternoon)]

23 : 44 : 35 : 56 : 43 : ?

Correct Answer: (d) 64
Solution:

1st number + 21 = 2nd number
In 23 : 44 ⇒ 23 + 21 = 44
In 35 : 56 ⇒ 35+ 21 = 56
Similarly,
43 : ? 43 + 21 = 64

42. Select the option that is related to the fifth letter cluster in the same way as the second letter - cluster is related to the first letter-cluster and the fourth letter cluster is related to the third letter cluster. [Group-D 20/09/2022 (Evening)]

Solution:

43. Select the set in which the numbers are related in the same way as are the numbers of the following sets. [Group - D 20/09/2022 (Evening)]

(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits.)
(7, 5, 16807)
(8, 4, 4096)

Correct Answer: (b) (12,3, 1728)
Solution:

(1st number) 2nd number = 3rd number
In (7, 5, 16807) ⇒ 7⁵ = 16807
In (8, 4, 4096) ⇒ 8⁴ = 4096
Similarly,
In (12, 3, 1728) ⇒ 12³= 1728

44. Select the option that is related to the fifth number in the same way as the second number is related to the first number and the fourth number is related to the third number. [Group-D 22/09/2022 (Morning)]

(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits.)
10 : 21 : 11 : 23 : 12 : ?

Correct Answer: (c) 25
Solution:

(1st number x 2 + 1) = 2nd number
In 10 : 21 ⇒ 10 × 2 + 1 = 21
In 11: 23 ⇒ 11 × 2 + 1 = 23 Similarly,
In 12 : ?⇒ 12 x 2 +1 = 25

45. Select the set in which the numbers are related in the same way as are the numbers of the following sets. [Group-D 22/09/2022 (Morning)]

(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits.)
(63, 72)
(28, 32)

Correct Answer: (b) (42,48)
Solution:

(63,72) ⇒ 7 × 9 = 63, 8 × 9 = 72
(28,32) ⇒ 7 × 4 = 28, 8 x 4 = 32
Similarly,
(42,48) ⇒ 7 × 6 = 42, 8 × 6 = 48

46. Select the option that is related to the fifth number in the same way as the second number is related to the first number and the fourth number is related to the third number. [Group-D 22/09/2022 (Afternoon)]

(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits.)
2 : 7 : 8 : 13 : 16 : ?

Correct Answer: (a) 21
Solution:

Logic used : first number + 5 = second number
In 2 : 72 + 5 = 7
In 8 : 13 ⇒ 8 + 5 = 13
Similarly,
In 16 : ? ⇒ 16+ 5 = 21

47. Select the option that is related to the fifth number in the same way as the second number is related to the first number and the fourth number is related to the third number. [Group-D 22/09/2022 (Evening)]

2 : 18 : 4 : 74 : 9 : ?

Correct Answer: (c) 739
Solution:

2nd number = (1st number)³ + 10
In 2 : 18 ⇒ 2³ +10 = 8 + 10 = 18
In 4 : 74 ⇒ 4³ + 10 = 64 + 10 = 74 Similarly,
In 9 : ? ⇒ 9³ + 10 = 729 + 10 = 739

48. In the given letter-cluster pairs, the first letter-cluster is related to the second letter-cluster following a certain logic. Study the given pairs carefully, and from the given options, select the pair that follows the same logic. [Group-D 22/09/2022 (Evening)]

AOE : FUJ
RKT : WQY

Correct Answer: (c) QEI: VKN
Solution:

1st letter + 5, 2nd letter + 6, 3rd letter + 5
In AOE : FUJ ⇒ A + 5 = F, 0 + 6 = U,
E + 5 = J
In RKT : WQY ⇒ R + 5 = W, K + 6 = Q,
T + 5 = Y
Similarly,
In QEI : VKN ⇒ Q + 5 = V, E+ 6 = K, 1+5 = N

49. In the given letter-cluster pairs, the first letter-cluster is related to the second letter-cluster following a certain logic. Study the given pairs carefully, and from the given options, select the pair that follows the same logic. [Group-D 26/09/2022 (Morning)]

QJD : TMG
GMS : JPV

Correct Answer: (c) RPH : USK
Solution:

In QJD : TMG  ⇒ Q + 3=T, J + 3 = M, D+3 = G
In GMS : JPV ⇒ G + 3 = J, M + 3 = P, S+3 = V
Similarly,
In RPH : USK ⇒ R + 3 = U, P + 3 = S, H + 3 = K

50. Select the set in which the numbers are related in the same way as are the numbers of the following sets. [Group-D 26/09/2022 (Morning)]

(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits.)
(7, 19, 40)
(12, 11, 47)

Correct Answer: (d) (16,5, 53)
Solution:

3rd number = 1st number x 3 + 2nd number
In (7, 19, 40) ⇒ 7 x 3 + 19 = 21+ 19 = 40
In (12, 11, 47)
⇒ 12 × 3 + 11 = 36 +11 = 47
Similarly,
In (16, 5, 53) ⇒ 16 x 3 + 5 = 48 + 5 = 53
