Odd One Out (SSC CGL 2020 Tier – 1)

The pattern followed here is :

(1^st letter + 2 = 2^nd letter), (3^rd letter = Opposite of 2^nd letter) & (3^rd letter - 5 = 4^th letter)

RTGB → (R + 2 = T), (T ↔ G) & (G - 5 = B)
LNMH → (L + 2 = N), (N ↔ M) & (M - 5 = H)
HJQL → (H + 2 = J), (J ↔ Q) & (Q - 5 = L)
But,

WYBY → (W + 2 = Y), (Y ↔ B) & (B - 5 ≠ Y)

Hence, WYBY is the correct answer.

But,

Gallop is a way in which horses travel.

Hence, "Gallop" is the correct answer.

{1^st letter + 4 = 2^nd letter}, {2^nd letter + 6 = 3^rd letter} & {3^rd letter + 8 = 4^th letter}

LPVD → (L + 4 = P), (P + 6 = V) & (V + 8 = D)
TXDL → (T + 4 = X), (X + 6 = D) & (D + 8 = L)

BFLT → (B + 4 = F), (P + 6 = L) & (L + 8 = T)

But,

LOCU → (L + 4 ≠ O), (O + 6 ≠ C) & (C + 8 ≠ U)

Hence, LOCU is the correct answer.

The pattern followed here is :

{2 × (1^st number)²} = 2^nd number

(11 : 242) → {2 × (11)²} ⇒ (2 × 121) = 242
(12 : 288) → {2 × (12)²} ⇒ (2 × 144) = 288

(14 : 392) → {2 × (14)²} ⇒ (2 × 196) = 392

But,

(19 : 622) → {2 × (19)²} ⇒ (2 × 361) = 722

Hence, (19 : 622) is the correct answer.

But,

Ecology is the study of organism and how they interact with the environment with them.

Hence, "Ecology" is the correct answer.

Sum of place value of all letters should be 44.

RDMI → (R = 18), (D = 4), (M = 13) & (I = 9) ⇒ 18 + 4 + 13 + 9 = 44

TFKG → (T = 20), (F = 6), (K = 11) & (G = 7) ⇒ 20 + 6 + 11 + 7 = 44

JNCQ → (J = 10), (N = 14), (C = 3) & (Q = 17) ⇒ 10 + 14 + 3 + 17 = 44

But,

FHWU → (F = 6), (H = 8), (W = 23) & (U = 21) ⇒ 6 + 8 + 23 + 21 = 58

Hence, FHWU is the correct answer.

The pattern followed here is :

{(6 × 1^st number) - 5} = 2^nd number

(28 : 163) → {(6 × 28) - 5} ⇒ (168 - 5) = 163
(22 : 127) → {(6 × 22) - 5} ⇒ (132 - 5) = 127

(16 : 91) → {(6 × 16) - 5} ⇒ (96 - 5) = 91

But,

(27 : 82) → {(6 × 27) - 5} ⇒ (162 - 5) = 157 ≠ 82

Hence, (27 : 82) is the correct answer.

The pattern followed here is :

{1^st letter - 4 = 2^nd letter}, {2^nd letter - 3 = 3^rd letter}

HDA → (H - 4 = D) & (D - 3 = A)
LHE → (L - 4 = H) & (H - 3 = E)
PLI → (P - 4 = L) & (L - 3 = I)
But,

WRO → (W - 4 ≠ R) & (R - 3 = O)
Hence, WRO is the correct answer.

The pattern followed here is :

{(√1^st number) + 1}³ = 2^nd number

(49 : 512) → {(√49 + 1)}³ ⇒ (7 + 1)³ ⇒ (8)³ = 512
(64 : 729) → {(√64 + 1)}³ ⇒ (8 + 1)³ ⇒ (9)³ = 729

(16 : 125) → {(√16 + 1)}³ ⇒ (4 + 1)³ ⇒ (5)³ = 125

But,

(36 : 353) → {(√36 + 1)}³ ⇒ (6 + 1)³ ⇒ (7)³ = 343

Hence, (36 : 353) is the correct answer.

The pattern followed here is :

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

RVEK → (R + 4 = V), (V ↔ E) & (E + 6 = K)
GKPV → (G + 4 = K), (K ↔ P) & (P + 6 = V)
CGTZ → (C + 4 = G), (G ↔ T) & (T + 6 = Z)

But,

NRIP → (N + 4 = R), (R ↔ I) & (I + 6 ≠ P)

Hence, NRIP is the correct answer.
