Total Questions: 50

31. 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 07/08/2023 (4th Shift)]

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

(a) 8 - 72
(b) 11 - 143
(c) 7 - 63
(d) 9 - 99

Correct Answer: (a) 8 - 72

Solution:The pattern followed here is :

{1^st number × (1^st number + 2)} = 2^nd number

(11 - 143) → {11 × (11 + 2)} ⇒ 11 × 13 = 143

(7 - 63) → {7 × (7 + 2)} ⇒ 7 × 9 = 63

(9 - 99) → {9× (9 + 2)} ⇒ 9 × 11 = 99

But,

(8 - 72) → {8 × (8 + 2)} ⇒ 8 × 10 = 80 (Not 72)

Hence, (8 - 72) is the correct answer.

32. 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 07/08/2023 (4th Shift)]

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

(a) 31 - 165
(b) 24 - 125
(c) 13 - 75
(d) 19 - 105

Correct Answer: (b) 24 - 125

Solution:The pattern followed here is :

{(1^st number + 2) × 5} = 2^nd number

(31 - 165) → {(31 + 2) × 5} ⇒ 33 × 5 = 165

(13 - 75) → {(13 + 2) × 5} ⇒ 15 × 5 = 75

(19 - 105) → {(19 + 2) × 5} ⇒ 21 × 5 = 105

But,

(24 - 125) → {(24 + 2) × 5} ⇒ 26 × 5 = 130 (Not 125)

Hence, (24 - 125) is the correct answer.

33. 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 07/08/2023 (4th Shift)]

(a) TSQ
(b) JHG
(c) PNM
(d) XVU

Correct Answer: (a) TSQ

Solution:The pattern followed here is :

Hence, TSQ is the correct answer.

34. Three of the following four letter-clusters 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 08/08/2023 (1st Shift)]

(a) PRT
(b) ACD
(c) UWY
(d) BDF

Correct Answer: (b) ACD

Solution:The pattern followed here is :

Hence, ACD is the correct answer.

35. Three of the following four letter-clusters 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 08/08/2023 (2nd Shift)]

(a) RSU
(b) XYA
(c) DEG
(d) ZAB

Correct Answer: (d) ZAB

Solution:The pattern followed here is :

Hence, ZAB is the correct answer.

36. Three of the following four letter-clusters 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 08/08/2023 (2nd Shift)]

(a) 5 : 45
(b) 2 : 10
(c) 3 : 21
(d) 4 : 32

Correct Answer: (b) 2 : 10

Solution:The pattern followed here is :

{1^st number × (1^st number + 4)} = 2^nd number

(5 : 45) → {5 × (5 + 4)} ⇒ 5 × 9 = 45

(3 : 21) → {3 × (3 + 4)} ⇒ 3 × 7 = 21

(4 : 32) → {4 × (4 + 4)} ⇒ 4 × 8 = 32

But,

(2 : 10) → {2 × (2 + 4)} ⇒ 2 × 6 = 12 (Not 10)

Hence, (2 : 10) is the correct answer.

37. 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 08/08/2023 (3rd Shift)]

(a) SQT
(b) BEH
(c) WUX
(d) FDG

Correct Answer: (b) BEH

Solution:The pattern followed here is :

Hence, BEH is the correct answer.

38. 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 08/08/2023 (4th Shift)]

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

(a) 19 : 370
(b) 17 : 298
(c) 11 : 130
(d) 15 : 244

Correct Answer: (d) 15 : 244

Solution:The pattern followed here is :

But,

(Not 244)

Hence, (15 : 244) is the correct answer.

39. Three of the following four letter-clusters 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 08/08/2023 (4th Shift)]

(a) WYZ
(b) EGH
(c) CEF
(d) TVX

Correct Answer: (d) TVX

Solution:The pattern followed here is :

Hence, TVX is the correct answer.

40. 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 08/08/2023 (4th Shift)]

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

(a) 17 - 14 - 15
(b) 33 - 26 - 25
(c) 39 - 33 - 30
(d) 22 - 18 - 20

Correct Answer: (b) 33 - 26 - 25

Solution:The pattern followed here is :

(1^st number - 2^nd number) × 5 = 3^rd number
(17 - 14 - 15) → {(17 - 14) × 5} = 15
(39 - 33 - 30) → {(39 - 33) × 5} = 30
(22 - 18 - 20) → {(22 - 18) × 5} = 20
But,

(33 - 26 - 25) → {(33 - 26) × 5} = 35 ≠ 25

Hence, (33 - 26 - 25) is the correct answer.
