31. Select the set in which the numbers are related in the same way as are the numbers of the following sets. [Group-D 01/09/2022 (Afternoon)]

(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits.)
(13, 182, 91)
(17, 306, 153)

Correct Answer: (c) 8, 72, 36
Solution:

let first number n the (n, n x (n + 1), second number x 0.5)= third number
(13, 182, 91) here 13 x 14 = 182
and 182 × 0.5 = 91
(17,306, 153) here 17 x 18 = 306
and 306 × 0.5 = 153
Similarly,
(8, 72, 36) here 8 x 9 = 72
and 72 × 0.5 = 36

32. 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 01/09/2022 (Afternoon)]

ASD : EWH
FGH : JKL

Correct Answer: (b) JKL: NOP
Solution:

ASD : EWH
FGH : JKL
Add (4) to each alphabet
JKL : NOP

33. 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 01/09/2022 (Evening)]

13 : 31 :: 15 : 33 :: 20 : ?

Correct Answer: (d) 38
Solution:

13+18 = 31; 15+ 18 = 33;
Similarly, 20 + 18 = 38

34. Select the set in which the numbers are related in the same way as are the numbers of the following sets. [Group-D 02/09/2022 (Afternoon)]

(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits.)
(33, 56)
(44, 67)

Correct Answer: (a) (5, 28)
Solution:

(a, a + 23) i.e.
33, (33 + 23) = 56
44, (44 + 23) = 67
Similarly, 5, (5 + 23) = 28

35. 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 05/09/2022 (Morning)]

59 : 45 : 46 : 24 :: 85 : ?

Correct Answer: (d) 40
Solution:

(59 : 45) ⇒ 59 ⇒ 5 × 9 = 45
(46 : 24) ⇒ 46 ⇒ 4 x 6 = 24
similarly
(85 : ?) ⇒ 85 ⇒ 8 x 5 = 40

36. PF 13 is related to MC 20 in a certain way. In the same way. LR 19 is related to 10 26. To which of the following is XJ 25 related following the same logic? [Group-D 05/09/2022 (Afternoon)]

Correct Answer: (b) UG 32
Solution:From the above sequence we can say XJ25 is related to UG32

37. 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 05/09/2022 (Evening)]

FLM : AGH :: MLK : HGF

Correct Answer: (c) RUG: MPB
Solution:

38. 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 05/09/2022 (Evening)]

72 : 90 :: 110 : 132 :: 156 : ?

Correct Answer: (b) 182
Solution:

(72 : 90) ⇒ 8 × 9 = 72 and 9 x 10 = 90
(110 : 132) ⇒ 10 x 11 = 110 and
11 x 12 = 132
Similarly,
(156 : 182) ⇒ 12 x 13 = 156 and 13 x 14 = 182

39. Select the set in which the numbers are related in the same way as are the numbers of the following sets. [Group-D 05/09/2022 (Evening)]

(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits.)
(15, 360, 12)
(12, 120, 5)

Correct Answer: (b) (14,84,3)
Solution:

Twice of (1st number × 3rd number) = 2nd number
Here,
2 x 15 x 12 = 360
2 x 12 x 5 = 120
Therefore,
2 x 14 x 3 = 84

40. 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 06/09/2022 (Morning)]

(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits.)
17 : 26 :: 5: 14 :: 22 : ?

Correct Answer: (c) 31
Solution:

{first num + 9} = second number
So, (17 : 26) ⇒ {17 + 9} = 26
(5 : 14) ⇒ {5 + 9} = 14
Similarly,
(22 : 31) ⇒ {22 + 9} = 31
