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? [SSC 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
Note:

Logic: (1st num - 2nd num) × 3 = 3rd num
16 - 9 - 21 → (16 - 9) × 3 = 7 × 3 = 21
23 - 18 - 15 → (23 - 18) × 3 = 5 × 3 = 15
34 - 28 - 18 → (34 - 28) × 3 = 6 × 3 = 18

But, 46 - 41 - 12 → (46 - 41) × 3 = 5 × 3 = 15 (NOT 12)

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? [SSC CHSL 02/08/2023 (1st Shift)]

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

Correct Answer: (d) MZK
Note:

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. [SSC 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
Note:

Logic: (1st num × 3) + 3 = 2nd num
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)

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. [SSC 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
Note:

Logic: (1st no. × 5) - 3 = 2nd no.
(17 × 5) - 3 = 82
(19 × 5) - 3 = 92
(47 × 5) - 3 = 232
But (31 × 5) - 3 = 152 ≠ 158

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? [SSC 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
Note:

Logic: (1st no.)² = 2nd no.
(21)² = 441
(23)² = 529
(19)² = 361
But, (16)² = 256 ≠ 276

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. [SSC CHSL 02/08/2023 (3rd Shift)]

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

Correct Answer: (b) UQT
Note:

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. [SSC CHSL 02/08/2023 (4th Shift)]

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

Correct Answer: (d) 14 - 42
Note:

Logic: (first number × 3) + 3 = second number
(17 × 3) + 3 = 54
(19 × 3) + 3 = 60
(15 × 3) + 3 = 48
But, (14 × 3) = 42

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? [SSC CHSL 02/08/2023 (4th Shift)]

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

Correct Answer: (d) NXR
Note:

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? [SSC CHSL 02/08/2023 (4th Shift)]

(1) 16 - 256
(2) 19 - 371
(3) 14 - 196
(4) 17 - 289

(a) 1
(b) 3
(c) 4
(d) 2

Correct Answer: (d) 2
Note:

Logic: (first number)² = second number
(16)² = 256 , (14)² = 196
(17)² = 289
But, (19)² = 361 and not 371

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? [SSC CHSL 03/08/2023 (1st Shift)]

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

Correct Answer: (d) TRV
