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. [SSC CGL 01/12/2022 (1st Shift)]

Correct Answer: (c) U V W
Solution:In HGF ⇒ H - 1 = G, G - 1 = F
In RQP ⇒ R - 1 = Q, Q - 1 = P
In UVW ⇒ U + 1 = V, V + 1 = W
In LKJ ⇒ L - 1 = K, K - 1 = J
We can see that all are following the same pattern except UVW.

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

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

Correct Answer: (a) 7 - 343 - 331
Solution:Logic: (n : n³ : n³ - 10)
(7, 343, 331) = (7 : 7³ : 7³ - 12)
(6, 216, 206) = (6 : 6³ : 6³ - 10)
(5, 125, 115) = (5 : 5³ : 5³ - 10)
(4, 64, 54) = (4 : 4³ : 4³ - 10)
Hence we can see that all are following the same pattern except (7, 343, 331).

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? [SSC CGL 01/12/2022 (2nd Shift)]

Correct Answer: (d) K G I
Solution:In TVR → T + 2 = V, V - 4 = R

In DFB ⇒ D + 2 = F, F - 4 = B
In QSO ⇒ Q + 2 = S, S - 4 = O
In KGI ⇒ K - 4 = G, G + 2 = I
We can see that all are following the same pattern except KGI.

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

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

Correct Answer: (a) 153 - 151 - 147
Solution:Logic - (1ˢᵗ number + 3ʳᵈ number) ÷ 2 = 2ⁿᵈ number
(153 + 147) ÷ 2 = 151
(171 + 167) ÷ 2 = 169
(183 + 179) ÷ 2 = 181
(201 + 195) ÷ 2 = 198

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.)

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. [SSC CGL 01/12/2022 (3rd Shift)]

Correct Answer: (c) J I G
Solution:In FDB ⇒ F - 2 = D, D - 2 = B
In ZXV ⇒ Z - 2 = X, X - 2 = V
In JIG ⇒ J - 1 = I, I - 2 = G
In LJH ⇒ L - 2 = J, J - 2 = H
Hence, we can see that all are following the same pattern except JIG.

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

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

Correct Answer: (a) 15 - 220 - 215
Solution:Logic : {n : n² : n² - 5}
(15, 220, 215) ⇒ (15 : 15² = 220 : 15² - 5 = 215)
(10, 100, 95) ⇒ (10 : 10² = 100 : 10² - 5 = 95)
(20, 400, 395) ⇒ (20 : 20² = 400 : 20² - 5 = 395)
(25, 625, 620) ⇒ (25 : 25² = 625 : 25² - 5 = 620)
Hence we can see that all are following the same pattern except (15, 220, 215).

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

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

Correct Answer: (b) 400 - 200 - 50
Solution:Logic:- (1ˢᵗ number) + 2 = 2ⁿᵈ number, (2ⁿᵈ number) ÷ 2 = 3ʳᵈ number
(600 - 300 - 150) ⇒ (600 ÷ 2) = 300, (300 ÷ 2) = 150
(400 - 200 - 50) ⇒ (400 ÷ 2) = 200, (200 ÷ 4) = 50
(1000 - 500 - 250) ⇒ (1000 ÷ 2) = 500, (500 ÷ 2) = 250
(100 - 50 - 25) ⇒ (100 ÷ 2) = 50, (50 ÷ 2) = 25
As we can clearly see, (400 - 200 - 50) is not following the pattern.

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

Correct Answer: (d) I R M T
Solution:In WDLF ⇒ W↔D (opposite) and L - 6 = F
In YBXR ⇒ Y↔B (opposite) and X - 6 = R
In PKSM ⇒ P↔K (opposite) and S - 6 = M
In IRMT ⇒ I↔R (opposite) and M + 7 = T
We can clearly see tha, IRMT is not following the pattern.

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

Correct Answer: (b) I R P
Solution:Logic: first two letter of word are opposite to each other and second

letter - 3 = third letter i.e.

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 in, IRP ⇒ I and R are opposite each other and R - 2 = P
Hence IRP does NOT belong to that group.
