Odd One Out (SSC CGL 2023 Tier – 1)

1. Find the odd number-pair. [SSC CGL 14/07/2023 (1st shift)]

(a) 20 : 11
(b) 6 : 4
(c) 15 : 9
(d) 12 : 7

Correct Answer: (c) 15 : 9

Solution:Logic: (Second number) × 2 - 2 = First number
20 : 11 : (11) × 2 - 2 = 22 - 2 = 20
6 : 4 : (4) × 2 - 2 = 8 - 2 = 6
12 : 8 : (8) × 2 - 2 = 16 - 2 = 12
But, 15 : 9 : (9) × 2 - 2 = 18 - 2 = 16 ≠ 15

2. Select the odd letter-cluster. [SSC CGL 14/07/2023 (1st shift)]

(a) BFJN
(b) DHLP
(c) HJKP
(d) JNRV

Correct Answer: (c) HJKP

Solution:

3. Which triad does NOT belong to the group? [SSC CGL 14/07/2023 (2nd shift)]

(a) 36 : 13 : 7
(b) 16 : 9 : 5
(c) 72 : 16 : 8
(d) 1 : 3 : 2

Correct Answer: (c) 72 : 16 : 8

Solution:Logic: (Second number - Third number)² = First number
36 : 13 : 7 — (13 - 7)² = 36
16 : 9 : 5 — (9 - 5)² = 16
1 : 3 : 2 — (3 - 2)² = 1
But, 72 : 16 : 8 — (16 - 8)² = 64 (Not 72)

4. Pick the odd one out. [SSC CGL 14/07/2023 (2nd shift)]

(a) KPH
(b) GTD
(c) DWA
(d) EVC

Correct Answer: (d) EVC

Solution:

5. Select the letter-cluster that is different. [SSC CGL 14/07/2023 (3rd shift)]

(a) DFJL
(b) KMOQ
(c) ACGI
(d) HJNP

Correct Answer: (b) KMOQ

Solution:

6. Find the odd number-pair. [SSC CGL 14/07/2023 (3rd shift)]

(NOTE: The relation should be found without breaking down the numbers into its constituent digits)

(a) 6286 : 1965
(b) 6571 : 2448
(c) 8247 : 3926
(d) 6903 : 2582

Correct Answer: (b) 6571 : 2448

Solution:Logic:
(First number - Second number) = 4321
(6286 : 1965) - (6286 - 1965) = 4321
(8247 : 3926) - (8247 - 3926) = 4321
(6903 : 2582) - (6903 - 2582) = 4321
But, (6571 : 2448) - (6571 - 2448) = 4123

7. Find the odd number pair. [SSC CGL 14/07/2023 (4th shift)]

(a) (87, 522)
(b) (84, 672)
(c) (92, 552)
(d) (64, 384)

Correct Answer: (b) (84, 672)

Solution:Logic:
(Second number ÷ First number) = 6
(87, 522) - (522 ÷ 87) = 6
(92, 552) - (552 ÷ 92) = 6
(64, 384) - (384 ÷ 64) = 6
But, (84, 672) - (672 ÷ 84) = 8 (Not 6)

8. Pick the odd one out. [SSC CGL 14/07/2023 (4th shift)]

(a) JQM
(b) DWG
(c) BXE
(d) AZD

Correct Answer: (c) BXE

Solution:

9. Which triad does NOT belong to the group? [SSC CGL 17/07/2023 (1st shift)]

(a) 12 : 47 : 60
(b) 4 : 16 : 20
(c) 2 : 7 : 10
(d) 5 : 19 : 25

Correct Answer: (b) 4 : 16 : 20

Solution:Logic:
(First num. + Second num.) + 1 = Third num.
12 : 47 : 60 — (12 + 47) + 1 = 60
22 : 7 : 10 — (7 + 7) + 1 = 10
5 : 19 : 25 — (5 + 19) + 1 = 25
But, 4 : 16 : 20 — (4 + 16) + 1 = 20

10. Three of the following four letter-clusters are alike in a certain way and one is different. Pick the odd one out. [SSC CGL 17/07/2023 (1st shift)]

(a) AFKP
(b) SXCH
(c) GKPS
(d) JOTY

Correct Answer: (c) GKPS
