Odd One Out (SSC CGL 2020 Tier – 1)

{(3 × 2^nd number) + 5} = 1^st number

(326 : 107) → {(3 × 107) + 5} ⇒ (321 + 5) = 326
(308 : 101) → {(3 × 101) + 5} ⇒ (303 + 5) = 308
(239 : 78) → {(3 × 78) + 5} ⇒ (234 + 5) = 239

But,

(197 : 66) → {(3 × 66) + 5} ⇒ (198 + 5) = 203 ≠ 197

Hence, (197 : 66) is the correct answer.

(Sum of digit of 2^nd number)² = 1^st number

(723 : 144) → (7 + 2 + 3)² ⇒ (12)² = 144
(546 : 225) → (5 + 4 + 6)² ⇒ (15)² = 225

(812 : 121) → (8 + 1 + 2)² ⇒ (11)² = 121

But,

(547 : 258) → (5 + 4 + 7)² ⇒ (16)² = 256 ≠ 258

Hence, (547 : 258) is the correct answer.

The pattern followed here is :

{(Sum of the digit of 1^st number) - (Sum of the digit of 2^nd number)} = 1

(727 : 609) → {(7 + 2 + 7) - (6 + 0 + 9)} ⇒ (16 - 15) = 1
(373 : 255) → {(3 + 7 + 3) - (2 + 5 + 5)} ⇒ (13 - 12) = 1
(797 : 679) → {(7 + 9 + 7) - (6 + 7 + 9)} ⇒ (23 - 22) = 1
But,

(191 : 177) → {(1 + 9 + 1) - (1 + 7 + 7)} ⇒ (11 - 15) = -4 ≠ 1
Hence, (191 : 177) is the correct answer.

The pattern followed here is :

{1^st letter + 2 = 2^nd letter}, {2^nd letter + 3 = 3^rd letter}

CEH → (C + 2 = E) & (E + 3 = H)
SUX → (S + 2 = U) & (U + 3 = X)
LNQ → (L + 2 = N) & (N + 3 = Q)

But,

JLP → (J + 2 = L) & (L + 3 ≠ P)

Hence, JLP is the correct answer.

The pattern followed here is :

{(3 × 1^st number) - 10} = 2^nd number

(54 : 152) → {(3 × 54) - 10} ⇒ (162 - 10) = 152
(36 : 98) → {(3 × 36) - 10} ⇒ (108 - 10) = 98

(82 : 236) → {(3 × 82) - 10} ⇒ (246 - 10) = 236

But,

(68 : 196) → {(3 × 68) - 10} ⇒ (204 - 10) = 194 ≠ 196

Hence, (68 : 196) is the correct answer.

The pattern followed here is :

{1^st letter + 2 = 2^nd letter}, {2^nd letter - 4 = 3^rd letter} & {3^rd letter + 6 = 4^th letter}

LNJP → (L + 2 = N), (N - 4 = J) & (J + 6 = P)
PRNT → (P + 2 = R), (R - 4 = N) & (N + 6 = T)
FHDJ → (F + 2 = H), (H - 4 = D) & (D + 6 = J)

But,

GIEY → (G + 2 = I), (I - 4 = E) & (E + 6 ≠ Y)

Hence, GIEY is the correct answer.

The pattern followed here is :

{1^st number + 13 = 2^nd letter} & {2^nd letter - 30 = 3^rd letter}

(63, 76, 46) → (63 + 13 = 76) & (76 - 30 = 46)
(83, 96, 66) → (83 + 13 = 96) & (96 - 30 = 66)
(72, 85, 55) → (72 + 13 = 85) & (85 - 30 = 55)
But,

(69, 84, 52) → (69 + 13 = 82 ≠ 84) & (82 - 30 = 52)
Hence, (69, 82, 52) is the correct answer.

But,

Taka is the currency of Bangladesh.

Hence, "Taka" is the correct answer.

The pattern followed here is :

{4 × (1^st number - 2)} = 2^nd number

(19 : 68) → {4 × (19 - 2)} ⇒ (4 × 17) = 68
(17 : 60) → {4 × (17 - 2)} ⇒ (4 × 15) = 60

(23 : 84) → {4 × (23 - 2)} ⇒ (4 × 21) = 84

But,

(13 : 90) → {4 × (13 - 2)} ⇒ (4 × 11) = 44 ≠ 90

Hence, (13 : 90) is the correct answer.

The pattern followed here is :

{4 × (1^st number)²} = 2^nd number

(7 : 196) → {4 × (7)²} ⇒ (4 × 49) = 196
(5 : 100) → {4 × (5)²} ⇒ (4 × 25) = 100

(6 : 144) → {4 × (6)²} ⇒ (4 × 36) = 144

But,

(4 : 52) → {4 × (4)²} ⇒ (4 × 16) = 64 ≠ 52

Hence, (4 : 52) is the correct answer.
