Odd One Out (SSC CHSL 2023 Tier – 1) (Part

Total Questions: 50

1. 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 02/08/2023 (1st Shift)]

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

(a) 46 - 41 - 12
(b) 16 - 9 - 21
(c) 23 - 18 - 15
(d) 34 - 28 - 18

Correct Answer: (a) 46 - 41 - 12

Solution:The logic followed here is :

(1^st number - 2^nd number) × 3 = 3^rd number
(16 - 9 - 21) → (16 - 9) × 3 = 21
(23 - 18 - 15) → (23 - 18) × 3 = 15
(34 - 28 - 18) → (34 - 28) × 3 = 18

But,

(46 - 41 - 12) → (46 - 41) × 3 = 15 (Not 12)

Hence, "46 - 41 - 12" is the correct answer

2. Based on the alphabetical order, 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 02/08/2023 (1st Shift)]

(a) TVR
(b) DFB
(c) WYU
(d) MZK

Correct Answer: (d) MZK

Solution:The pattern followed here is :

But,

Hence, MZK is the correct answer.

3. 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 02/08/2023 (1st Shift)]

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

(a) 46 - 141
(b) 55 - 168
(c) 35 - 108
(d) 29 - 88

Correct Answer: (d) 29 - 88

Solution:The Logic followed here is :

(1^st number × 3) + 3 = 2^nd number
(46 - 141) → (46 × 3) + 3 ⇒ 138 + 3 = 141
(55 - 168) → (55 × 3) + 3 ⇒ 165 + 3 = 168
(35 - 108) → (35 × 3) + 3 ⇒ 105 + 3 = 108
But,

(29 - 88) → (29 × 3) + 3 ⇒ 87 + 3 = 90 (NOT 88)

Hence, "29 - 88" is the correct answer.

4. 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 02/08/2023 (3rd Shift)]

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

(a) 31 : 158
(b) 47 : 232
(c) 17 : 82
(d) 19 : 92

Correct Answer: (a) 31 : 158

Solution:The logic followed here is :

(1^st number × 5) - 3 = 2^nd number
(17 : 82) → (17 × 5) - 3 = 82
(19 : 92) → (19 × 5) - 3 = 92
(47 : 232) → (47 × 5) - 3 = 232
But,

(31 : 158) → (31 × 5) - 3 = 152 ≠ 158

Hence, (31 : 158) is the correct answer.

5. 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 02/08/2023 (3rd Shift)]

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

(a) 16 - 276
(b) 23 - 529
(c) 21 - 441
(d) 19 - 361

Correct Answer: (a) 16 - 276

Solution:The logic followed here is :

(1^st number)² = 2^nd number
(21 -441) → (21)² = 441
(23 - 529) → (23)² = 529
(19 - 361) → (19)² = 361
But,

(16 - 276) → (16)² = 256 ≠ 276

Hence, (16 - 276) is the correct answer.

6. 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 02/08/2023 (3rd Shift)]

(a) LPM
(b) UQT
(c) EIF
(d) PTQ

Correct Answer: (b) UQT

Solution:The pattern followed here is :

But,

Hence, UQT is the correct answer.

7. 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 02/08/2023 (4th Shift)]

(a) 17 - 54
(b) 19 - 60
(c) 15 - 48
(d) 14 - 42

Correct Answer: (d) 14 - 42

Solution:The logic followed here is :

(1^st number × 3) + 3 = 2^nd number
(17 - 54) → (17 × 3) + 3 = 54
(19 - 60) → (19 × 3) + 3 = 60
(15 - 48) → (15 × 3) + 3 = 48
But, (14 - 42) → (14 × 3) + 3 = 45 ≠ 42

Hence, (14 - 42) is the correct answer.

8. Based on the alphabetical order, 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 02/08/2023 (4th Shift)]

(a) JQN
(b) ELI
(c) ZGD
(d) NXR

Correct Answer: (d) NXR

Solution:The logic followed here is :

Hence, NXR is the correct answer.

9. 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 02/08/2023 (4th Shift)]

(a) 16 - 256
(b) 17 - 289
(c) 14 - 196
(d) 19 - 371

Correct Answer: (d) 19 - 371

Solution:The logic followed here is :

(1^st number)² = 2^nd number
(16 - 256) → (16)² = 256
(17 - 289) → (17)² = 289
(14 - 196) → (14)² = 196

But,

(19 - 371) → (19)² = 361 and not 371

Hence, (19 - 371) is the correct answer.

10. Three of the following four letter-clusters are alike in some manner and hence form a group. Which letter-cluster does not belong to that group? [S.S.C CHSL 03/08/2023 (1st Shift)]

(a) MKN
(b) QOR
(c) GEH
(d) TRV

Correct Answer: (d) TRV

Solution:The pattern followed here is :

Hence, TRV is the correct answer.
