Odd One Out (SSC CGL 2022 Tier – 1)

Total Questions: 54

1. Three of the following four letter-clusters are alike in a certain way and one is different. Pick the odd one out. [S.S.C CGL 01/12/2022 (1st Shift)]

(a) HGF
(b) RQP
(c) UVW
(d) LKJ

Correct Answer: (c) UVW

Solution:The pattern followed here is :

Letters are in reverse order

HGF ⇒ H - 1 = G, G - 1 = F
RQP ⇒ R - 1 = Q, Q - 1 = P
LKJ ⇒ L - 1 = K, K - 1 = J
But,

UVW ⇒ U + 1 = V, V + 1 = W

Hence, UVW is the correct answer.

2. Select the odd group of numbers. [S.S.C CGL 01/12/2022 (1st Shift)]

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

(a) 7 - 343 - 331
(b) 6 - 216 - 206
(c) 5 - 125 - 115
(d) 4 - 64 - 54

Correct Answer: (a) 7 - 343 - 331

Solution:The pattern followed here is :

(n : n³ : n³ - 10) (1^stnumber)³ = 2^ndnumber & (2^ndnumber - 10) = 3^rdnumber
(6 - 216 - 206) → 6³ = 216 & (216 - 10) = 206
(5 - 125 - 115) → 5³ = 125 & (125 - 10) = 115
(4 - 64 - 54) → 4³ = 64 & (64 - 10) = 54

(7 - 343 - 331) → 7³ = 343 & (343 - 10) = 333 ≠ 331

Hence, (7 - 343 - 331) is the correct answer.

3. Three of the following letter-clusters are alike in some manner and hence form a group. Which letter-cluster does not belong to that group? [S.S.C CGL 01/12/2022 (2nd Shift)]

(a) TVR
(b) DFB
(c) QSO
(d) KGI

Correct Answer: (d) KGI

Solution:The pattern followed here is :

TVR → (T + 2 = V), (V - 4 = R)

DFB → (D + 2 = F), (F - 4 = B)
QSO → (Q + 2 = S), (S - 4 = O)

But,
KGI → (K - 4 = G), (G + 2 = I)
Hence, KGI is the correct answer.

4. Select the odd group of numbers. [S.S.C CGL 01/12/2022 (2nd Shift)]

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

(a) 153 - 151 - 147
(b) 171 - 169 - 167
(c) 183 - 181 - 179
(d) 201 - 198 - 195

Correct Answer: (a) 153 - 151 - 147

Solution:The pattern followed here is :

{(1^st number + 3^rd number) ÷ 2} = 2^nd number
(171 - 169 - 167) → {(171 + 167) ÷ 2} = 169
(183 - 181 - 179) → {(183 + 179) ÷ 2} = 181
(201 - 198 - 195) → {(201 + 195) ÷ 2} = 198

But,

(153 - 151 - 147) → {(153 + 147) ÷ 2} = 150 ≠ 147

Hence, (153 - 151 - 147) is the correct answer.

5. Select the odd group of numbers. [SSC CGL 01/12/2022 (3rd Shift)]

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

(a) 92 - 72 - 52
(b) 76 - 56 - 36
(c) 98 - 78 - 56
(d) 68 - 48 - 28

Correct Answer: (c) 98 - 78 - 56

Solution:Logic : Difference between 1ˢᵗ and 2ⁿᵈ number is equal to difference between 2ⁿᵈ and 3ʳᵈ number.
(92, 72, 52) ⇒ (92 - 72) = (72 - 52)
(76, 56, 36) ⇒ (76 - 56) = (56 - 36)
(98, 78, 56) ⇒ (98 - 78) ≠ (78 - 56)
(88, 68, 48) ⇒ (88 - 68) = (68 - 48)
Hence we can see that all are following the same pattern except (98, 78, 56).

6. Pick the odd one out. [S.S.C CGL 01/12/2022 (3rd Shift)]

(a) FDB
(b) ZXV
(c) JIG
(d) LJH

Correct Answer: (c) JIG

Solution:The pattern followed here is :

FDB → (F - 2 = D), (D - 2 = B)
ZXV → (Z - 2 = X), (X - 2 = V)
LJH → (L - 2 = J), (J - 2 = H)
But,

JIG → (J - 2 = H ≠ I), (I - 2 = G)

Hence, JIG is the correct answer.

7. Select the odd group of numbers. [S.S.C CGL 01/12/2022 (4th Shift)]

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

(a) 15 - 220 - 215
(b) 10 - 100 - 95
(c) 20 - 400 - 395
(d) 25 - 625 - 620

Correct Answer: (a) 15 - 220 - 215

Solution:The pattern followed here is :

(1^st number)² = 2^ndnumber & (2^ndnumber - 5) = 3^rdnumber
(10 - 100 - 95) → (10² = 100) & (100 - 5 = 95)
(20 - 400 - 395) → (20² = 400) & (400 - 5 = 395)
(25 - 625 - 620) → (25² = 625) & (625 - 5 = 620)

(15 - 220 - 215) → (15² = 225 ≠ 220) & (220 - 5 = 215)
Hence, (15 - 220 - 215) is the correct answer.

8. Select the odd group of numbers. [S.S.C CGL 02/12/2022 (1st Shift)]

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

(a) 600 - 300 - 150
(b) 400 - 200 - 50
(c) 1000 - 500 - 250
(d) 200 - 100 - 50

Correct Answer: (b) 400 - 200 - 50

Solution:The pattern followed here is :

(1^st number) ÷ 2 = 2^nd number & (2^nd number) ÷ 2 = 3^rd number
(600 - 300 - 150) → (600 ÷ 2) = 300 & (300 ÷ 2) = 150
(1000 - 500 - 250) → (1000 ÷ 2) = 500, (500 ÷ 2) = 250
(100 - 50 - 25) → (100 ÷ 2) = 50, (50 ÷ 2) = 25

But,

(400 - 200 - 50) → (400 ÷ 2) = 200 & (200 ÷ 2) = 100 ≠ 50
Hence, (400 - 200 - 50) is the correct answer.

9. Which letter-cluster does not belong to the group? [S.S.C CGL 02/12/2022 (1st Shift)]

(a) WDLF
(b) YBXR
(c) PKSM
(d) IRMT

Correct Answer: (d) IRMT

Solution:The pattern followed here is :

WDLF → W↔D (opposite) and L - 6 = F
YBXR → Y↔B (opposite) and X - 6 = R
PKSM → P↔K (opposite) and S - 6 = M

But,
IRMT → I↔R (opposite) and M + 7 = T

Hence, IRMT is the correct answer.

10. Which letter-cluster does not belong to the group? [S.S.C CGL 02/12/2022 (2nd Shift)]

(a) EVS
(b) IRP
(c) VEB
(d) GTQ

Correct Answer: (b) IRP

Solution:The pattern followed here is :

EVS → E and V are opposite to each other and V - 3 = S
VEB → V and E are opposite to each other and E - 3 = B
GTQ → G and T are opposite to each other and T - 3 = Q
But,

IRP → I and R are opposite each other and R - 2 = P
Hence, IRP is the correct answer.
