11. Select the set in which the numbers are related in the same way as are the numbers of the following sets. [Group-D 22/08/2022 (Morning)]

(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits.)
(24, 12, 72)
(15, 16, 60)

Correct Answer: (d) (20, 24, 120)
Solution:

12. Select the set in which the numbers are related in the same way as are the numbers of the following sets. [Group-D 22/08/2022 (Afternoon)]

(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits.)
(11,57,8)
(12, 63, 9)

Correct Answer: (b) (10, 64, 6)
Solution:

(First number)² − (Third number) = Second number
i.e. (11, 57,8) ⇒ 11² − 8² = 57
(12,63,9) ⇒ 12² − 9² = 63
Similarly
(10,64,6) ⇒ 10² − 6² = 64

13. Select the set in which the members are related in the same way as are the numbers of the following sets. [Group-D 22/08/2022 (Evening)]

(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits.)
(8, 188, 12)
(5, 62, 7)

Correct Answer: (d) 7,114,9
Solution:(first number)² + ( third number)² - first number - third number = Second number
(5, 62, 7) ⇒ (5)² + (7)² - 5 - 7 = 62
(8, 188, 12) ⇒ (8)² + (12)² - 8 - 12 = 188
Similarly
(7, 144, 9) ⇒ (7)² + (9)² - 7 - 9 = 114

14. 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 23/08/2022 (Afternoon)]

14 : 203 :: 16 : 264 : 18 : ?

Correct Answer: (c) 333
Solution:(14 : 203) ⇒ 14² + 14/2 =203
(16 : 264) ⇒ 16² + 16/2 =264
Similarly
(18 : 333) ⇒ 18² + 18/2 =333

15. KIT 20 is related to PRG 50 in a certain way. In the same way, ENT 16 is related to VMG 40. To which of the following is MFG 18 related following the same logic? [Group-D 23/08/2022 (Afternoon)]

Correct Answer: (c) NUT 45
Solution:

16. BTE 11 is related to DVG120 in a certain way. In the same way, PAN 9 is related to RCP 80. To which of the following is GMT 12 related following the same logic? [Group-D 24/08/2022 (Morning)]

Correct Answer: (c) IOV 143
Solution:

17. Select the set in which the numbers are related in the same way as are the numbers of the following sets. [Group-D 24/08/2022 (Evening)]

(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits.)
(2, 4, 18)
(4, 6, 50)

Correct Answer: (b) (3, 5, 32)
Solution:

[(1st number × 2nd number) + 1] x 2 = 3rd number
(2, 4, 18) ⇒ [(2 x 4)+1] x2 = 18
(4, 6, 50) ⇒ [(4x6) + 1]x 2 = 50
Similarly,
(3, 5, 32) ⇒ [(3 x 5) + 1] x 2 = 32

18. Select the option which 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 26/08/2022 (Afternoon)]

34 : 51:  28 : 42 :: 46 : ?

Correct Answer: (c) 69
Solution:

34 : 51 ⇒ 17 (2:3)
28:42 14 (2:3)
Similarly,
46:69 ⇒ 23 (2 : 3)
Hence, ?= 69

19. 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 29/08/2022 (Afternoon)]
