Total Questions: 50

11. The second number in the given number pairs is obtained by performing certain mathematical operation(s) on the first number. The same operation(s) are followed in all the number pairs except one. Find that odd number pair. [S.S.C CHSL 03/08/2023 (1st Shift)]

(a) 5 : 23
(b) 4 : 19
(c) 2 : 11
(d) 7 : 32

Correct Answer: (d) 7 : 32

Solution:The logic followed here is :

(1^st number × 4) + 3 = 2^nd number

(5 : 23) → (5 × 4) + 3 ⇒ 20 + 3 = 23
(4 : 19) → (4 × 4) + 3 ⇒ 16 + 3 = 19
(2 : 11) → (2 × 4) + 3 ⇒ 8 + 3 = 11
But,

(7 : 32) → (7 × 4) + 3 ⇒ 28 + 3 = 31 (NOT 32)

Hence, (7 : 32) is the correct answer.

12. Four number pairs have been given, out of which three are alike in some manner and one is different. Select the one that is different. [S.S.C CHSL 03/08/2023 (2nd Shift)]

(a) 4 : 75
(b) 2 : 19
(c) 6 : 212
(d) 5 : 136

Correct Answer: (c) 6 : 212

Solution:The logic followed here is :

(1^st number)³ + 11 = 2^nd number
(4 : 75) → 4 + 11 ⇒ 64 + 11 = 75

(2 : 19) → 2 + 11 ⇒ 8 + 11 = 19

(5 : 136) → 5³ + 11 ⇒ 125 + 11 = 136

But,
(6 : 212) → (6) + 11 ⇒ 216 + 11 = 227 (Not 212)

Hence, 6 : 212 is the correct answer.

13. Four number pairs have been given, out of which three are alike in some manner and one is different. Select the one that is different. [S.S.C CHSL 03/08/2023 (2nd Shift)]

(a) 15 - 225
(b) 19 - 361
(c) 9 - 81
(d) 4 - 64

Correct Answer: (d) 4 - 64

Solution:The logic followed here is :

(1^st number)² = 2^nd number

(15 - 225) → (15)² = 225
(19 - 361) → (19)² = 361
(9 - 81) → (9)² = 81
But,

(4 - 64) → (4)² = 16 ≠ 64

Hence, (4 - 64) is the correct answer.

14. Select the word-pair that does not represent a similar relationship to the one expressed in the pair of words given below. [S.S.C CHSL 03/08/2023 (3rd Shift)]

Rapidly : Swiftly

(a) Obtain : Procure
(b) Distress : Trouble
(c) True : Correct
(d) Idle : Active

Correct Answer: (d) Idle : Active

Solution:Rapidly is the synonym of Swiftly but Idle is the antonym of Active.
So (Idle : Active) is the word-pair that does not represent a similar relationship with the question pair.

15. Four terms have been given, out of which three are alike in some manner and one is different. Select the one that is different. [S.S.C CHSL 03/08/2023 (3rd Shift)]

(a) TVD
(b) FHP
(c) LNV
(d) KMV

Correct Answer: (d) KMV

Solution:The pattern followed here is :

But,

Hence, KMV is the correct answer.

16. Three of the following four letter-clusters are alike in a certain way and thus form a group. Which is the one that does NOT belong to that group? [S.S.C CHSL 03/08/2023 (4th Shift)]

(a) XVU
(b) TQP
(c) CAZ
(d) KIH

Correct Answer: (b) TQP

Solution:The pattern followed here is :

But,

Hence, TQP is the correct answer.

17. Three of the following four are alike in a certain way and thus form a group. Which is the one that does NOT belong to that group? [S.S.C CHSL 03/08/2023 (4th Shift)]

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

(a) 7 - 56
(b) 9 - 90
(c) 4 - 20
(d) 6 - 48

Correct Answer: (d) 6 - 48

Solution:The pattern followed here is :

(1^st number) × (1^st number + 1) = 2^nd number
(7 - 56) → 7 × (7 + 1) ⇒ 7 × 8 = 56
(9 - 72) → 9 × (9 + 1) ⇒ 9 × 10 = 90
(4 - 20) → 4 × (4 + 1) ⇒ 4 × 5 = 20
But,

(6 - 48) → 6 × (6 + 1) ⇒ 6 × 7 = 42 (Not 48)

Hence, (6 - 48) is the correct answer.

18. Four terms have been given, out of which three are alike in some manner and one is different. Select the one that is different. [S.S.C CHSL 04/08/2023 (1st Shift)]

(a) LNT
(b) GJP
(c) BDJ
(d) TVB

Correct Answer: (b) GJP

Solution:The pattern followed here is :

But,

Hence GJP is the correct answer.

19. Three of the following four are alike in a certain way and thus form a group. Which is the one that does NOT belong to that group? [S.S.C CHSL 04/08/2023 (1st Shift)]

(a) 18 - 325
(b) 13 - 168
(c) 15 - 224
(d) 11 - 120

Correct Answer: (a) 18 - 325

Solution:The pattern followed here is :
(1^st number)² - 1 = 2^nd number
(11 - 120) → (11)² - 1 = 120
(13 - 168) → (13)² - 1 = 168
(15 - 224) → (15)² - 1 = 224
But,

(18 - 325) → (18)² - 1 = 323 ≠ 325

Hence, (18 - 325) is the correct answer.

20. Four number-pairs have been given, out of which three are alike in some manner and one is different. Select the one that is different. [S.S.C CHSL 04/08/2023 (1st Shift)]

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

(a) 21 : 182
(b) 11 : 92
(c) 17 : 146
(d) 31 : 284

Correct Answer: (d) 31 : 284

Solution:The pattern followed here is :
(1^st number × 9) - 7 = 2^nd number
(11 : 92) → (11 × 9) - 7 = 92
(17 : 146) → (17 × 9) - 7 = 146
(21 : 182) → (21 × 9) - 7 = 182
But,
(31 : 284) → (31 × 9) - 7 = 272 (not 284)

Hence, (31 : 284) is the correct answer.
