1. 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 12/09/2022 (Morning)]

9 : 83 :: 5 : 47 :: 4 : ?

Correct Answer: (b) 38
Solution:

a : (a x 9 + 2) i.e.
9 : (9 x 9 +2) = 83
5 : (5 x 9 +2) = 47
Similarly, 4: (4 x 9 + 2) = 38

2. 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 12/09/2022 (Afternoon)]

9 :90 :: 5 : 30 :: 10 : ?

Correct Answer: (b) 110
Solution:

a : (a²+ a) i.e.
9 : (9² + 9) = 90
5 : (5 + 5) =30
Similarly, 10 : (10 + 10) = 110

3. Select the option in which the numbers are related in the same way as are the numbers of the given sets. [Group-D 12/09/2022 (Evening)]

(NOTE: Operations should be performed on the whole numbers without breaking down the numbers into its constituent digits.)
(8, 19, 22)
(3, 9, 12)

Correct Answer: (d) (17, 21,8)
Solution:

Subtract second number from the first number and
multiply by 2.
19 - 8 =11 x 2 = 22
9 - 3 = 6 × 2 = 12
Similarly,
21 - 17 = 4 x 2 =8

4. Select the option in which the numbers are related in the same way as are the numbers of the given sets. [Group-D 13/09/2022 (Morning)]

(NOTE: Operations should be performed on the whole numbers without breaking down the numbers into its constituent digits.)
(2, 42, 4)
(7, 57, 5)

Correct Answer: (b) (3, 83, 8)
Solution:

(Third number x 10 + First number = Second number) i.e.
(2, 42, 4) ⇒ (4 x 10 + 2) = 42
(7, 57, 5) ⇒ (5 x 10+7) = 57
Similarly, (3, 83, 8) ⇒ (8 x 10 + 3) = 83

5. 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 13/09/2022 (Morning)]

12 : 18 :: 28 : 42 :: 10 : ?

Correct Answer: (b) 15
Solution:

a : (a + a/2 ) i.e.
12 : (12 + 12/2) = 18
28 : (28 + 28/2) = 42
Similarly, 10 : (10 + 10/2) = 15

6. Select the option in which the numbers are related in the same way as are the numbers of the given sets. [Group-D 13/09/2022 (Afternoon)]

(NOTE: Operations should be performed on the whole numbers without breaking down the numbers into its constituent digits.)
(6,7,8)
(23, 34, 45)

Correct Answer: (a) (7, 12, 17)
Solution:

first number + third number ÷ 2 = second number
In: (6, 7, 8) ⇒ 6+8 ÷ 2 = 7
In: (23, 34, 45) ⇒ 23 + 45 ÷ 2 = 34
similarly
In: (7, 12, 17) ⇒ 7+17 ÷ 2 = 12

7. Select the set in which the numbers are related in the same way as are the numbers of the following sets. [Group-D 13/09/2022 (Evening)]

(NOTE: Operations should be performed on the whole numbers, without breaking down he numbers into its constituent digits.)
(15,450, 10)
(12, 540, 15)

Correct Answer: (d) (11,330, 10)
Solution:

(first number x third number) × 3 = second number
In: (15, 450, 10) ⇒ (15 x 10) × 3 = 450
In : (12,540, 15) ⇒ (12 x 15) × 3 = 540
similarly
In : (11, 330, 10) ⇒ (11 x 10) × 3 = 330

8. 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 13/09/2022 (Evening)]

DHP : HLT
MSO : QWS

Correct Answer: (d) SKF : WOJ
Solution:

9. Select the set in which the numbers are related in the same way as are the numbers of the following sets. [Group-D 14/09/2022 (Morning)]

(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits.)
(28, 33, 48)
(67, 72, 87)

Correct Answer: (d) (29, 34, 49)
Solution:

first number + 5 = second number,
second number + 15 = third number
In: (28, 33, 48) ⇒ 28+ 5
= 33, 33 + 15 = 48
In: (67, 72, 87)
⇒ 67 + 5 = 72, 72 + 15 = 87
similarly
In: (29, 34, 49)
⇒ 29 + 5 = 34, 34 + 15 = 49

10. Select the set in which the numbers are related in the same way as are the numbers of the following sets. [Group-D 14/09/2022 (Afternoon)]

(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits.)(10,144)
(17, 361)

Correct Answer: (d) (21, 529)
Solution:

(1st term + 2)² = 2nd term
In: (10, 144) ⇒ (10 + 2)² = (12)² = 144
In: (17,361) ⇒ (17+ 2)² = (19)² = 361
similarly
In: (21, 529) ⇒ (21+ 2)²= (23)²= 529
