11. 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 14/09/2022 (Afternoon)]

13 : 19 : 37 : 31 : ?

Correct Answer: (a) 41
Solution:

In: (13: 19) 19 is the second prime number after 13
In: (3 : 7) ⇒ 7 is the second prime
number after 3
Similarly
In: (31 : ?) ⇒ 41 is the second prime
number after 31

12. 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 14/09/2022 (Afternoon)]

Solution:

13. 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 14/09/2022 (Evening)]

72 : 90 :: 48 : 60 :: 24 : ?

Correct Answer: (d) 30
Solution:

In: (72,90) ⇒ 18 x 4 = 72, 18 x 5 = 90
In: (48, 60) ⇒ 12 x 4 = 48, 12 x 5 = 60
Similarly
In: (24, ?) = 6 x 4 = 24, 6 x 5 = 30
(?= 30)

14. Select the option that is related to the letter - cluster in the same way as the second letter cluster is related to the letter-cluster and the fourth letter cluster is related to the third letter - cluster. [Group-D 15/09/2022 (Morning)]

1 2 3 4 5 6
MO D E R N

5 2  6  1  4  3
R O N M E D

G E R M A  N
5 2  6 1  4  3
A E N G M R

Similarly
1 2 3 4 5 6
J U N I O R

5 2 6 1 4 5 6
O U R  J  I  N

15. 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 to the third number. [Group-D 15/09/2022 (Morning)]

14 : 20 : 26 : 38 :: 18 : ?

Correct Answer: (b) 26
Solution:

(first term x 1.5-1) = second term
In: (14 : 20) = 14 × 1.5 - 1 = 20
In: (26 : 38) = 26 x 1.5 - 1 = 38 Similarly,
In: (18 : ?) = 18 x 1.5 - 1 = 26

16. 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 15/09/2022 (Morning)]

6 : 64 :: 11 : 169 :: 8 : ?

Correct Answer: (d) 100
Solution:

(1st number + 2)² = second number
In: (6 : 64) ⇒ (6 + 2)² = 64
In: (11:169) ⇒ (11 + 2)²= 169
Similarly
In: (8 : ?) ⇒ (8 + 2)² = 100

17. Select the option that is related to the seventh number in the same way as the second number is related to the first number, the fourth number to the third number and the sixth number is related to the fifth number. [Group-D 15/09/2022 (Afternoon)]

20 : 5 : 56 : 8 :: 12 : 4 :: 42 : ?

Correct Answer: (a) 7
Solution:

first term = (2nd term) x (2nd term - 1)
In 20 : 5 ⇒ 5 × 4 = 20
In 56 : 8 ⇒ 8 × 7 = 56
In 12:4 ⇒ 4 × 3 = 12
Similarly,
In 42 : ? ⇒ 7× 6 = 42

18. Select the set in which the numbers are related in the same way as are the numbers of the following sets. [Group-D 15/09/2022 (Evening)]

(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits.)
(10, 300, 10)
(11,165, 5)

Correct Answer: (d) (9, 243, 9)
Solution:

(First number x Third number) x 3 = Second number
In (10, 300, 10):- (10 x 10) x 3 = 300
In (11, 165, 5):- (11 x 5) x 3 = 165
Similarly, (9, 243, 9) - (9 x 9) x 3 = 243

19. 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 15/09/2022 (Evening)]

HP : MS
DL : 10

Correct Answer: (b) AL : FO
Solution:

In HP : MS, H+ 5 = M and P+3 = S
In DL: 1O, D + 5 = 1 and L +3 = O Similarly,
In AL: FO, A + 5 = F and L +3 = O

20. Select the option that is related to the fifth number in the same way as the fourth number is related to the third number and the second number is related to the first number. [Group-D 15/09/2022 (Evening)]

58 : 115 :: 47 : 93 :: 67 : ?

Correct Answer: (b) 133
Solution:

In 58 :115 ⇒ 58 x 2 -1 = 115
In 47: 93 ⇒ 47 x 2 -1 = 93
Similarly,
67 : ? => 67 x 2 -1 = 133
