Odd One Out (SSC CGL 2020 Tier – 1)

{2^nd letter + 1234 = 1^st number}

(2347 : 1113) → (1113 + 1234) = 2347
(3527 : 2293) → (2293 + 1234) = 3227
(5237 : 4003) → (4003 + 1234) = 5237

But,

(4327 : 2003) → (2003 + 1234) = 3237 ≠ 4327

Hence, (4327 : 2003) is the correct answer.

The pattern followed here is :

{2^nd number × (2^nd number + 3) + 1} = 1^st letter}

(461 : 20) → {20 × (20 + 3) + 1} = 461
(239 : 14) → {14 × (14 + 3) + 1} = 239

(305 : 16) → {16 × (16 + 3) + 1} = 305

But,

(182 : 12) → {12 × (12 + 3) + 1} = 181 ≠ 182

Hence, (182 : 12) is the correct answer.

The pattern followed here is :

{1^st letter + 5 = 2^nd letter}, {2^nd letter + 6 = 3^rd letter}

LQW → (L + 5 = Q) & (Q + 6 = W)
TYE → (T + 5 = Y) & (Y + 6 = E)

NSY → (N + 5 = S) & (Q + 6 = Y)

But,

PUB → (P + 5 = U) & (U + 6 ≠ B)

Hence, PUB is the correct answer.

The pattern followed here is :

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

KPSH → (K ↔ P), (P + 3 = S) & (S ↔ H)

JQTG → (J ↔ Q), (Q + 3 = T) & (T ↔ G)

DWZA → (D ↔ W), (W + 3 = Z) & (Z ↔ A)

But,

SHLO → (S ↔ H), (H + 3 ≠ L) & (L ↔ O)

Hence, SHLO is the correct answer.

(2^nd number - 1^st number) = number should be a perfect square.

(61 : 97) → (97 - 61) = 36 = 6²
(78 : 127) → (127 - 78) = 49 = 7²

(25 : 89) = (89 - 25) = 64 = 8²

But,

(56 : 136) = (136 - 56) = 80 = not a perfect square.
Hence, (56 : 136) is the correct answer.

The pattern followed here is :

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

NQT → (N + 3 = Q), (Q + 3 = T)
PSV → (P + 3 = S), (S + 3 = V)
MPS → (M + 3 = P), (P + 3 = S)

But,

QTV → Q + 3 = T, T + 3 ≠ V

Hence, QTV is the correct answer.

But,

(324335 : 577) → 32 - 43 - 35 ⇒ (3 + 2)(4 + 3)(3 + 5) = 578 ≠ 577

Hence, (324335 : 577) is the correct answer.

But,

Psychiatrists treat mental illness.

Hence, "Psychiatrists" is the correct answer.

{(1^st number)² + 6} = 2^nd number

(25 : 631) → {(25)² + 6} ⇒ (625 + 6) = 631
(22 : 490) → {(22)² + 6} ⇒ (484 + 6) = 490
(21 : 447) → {(21)² + 6} ⇒ (441 + 6) = 447

But,

(30 : 908) → {(30)² + 6} ⇒ (900 + 6) = 906 ≠ 908

Hence, (30 : 908) is the correct answer.
