Odd One Out (SSC CHSL 2020 Tier – 1)

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}

GKPJ → (G + 4 = K), (K ↔ P) & (P - 6 = J)

KOLF → (K + 4 = O), (O ↔ L) & (L - 6 = F)

QUFZ → (Q + 4 = U), (U ↔ F) & (F - 6 = Z)

But,

TXBV → (T + 4 = X), (X ↔ C ≠ B) & (B - 6 = V)

Hence, TXBV is the correct answer.

The pattern followed here is :

{1^st letter + 3 = 2^nd letter}, {2^nd letter + 4 = 3^rd letter} & {3^rd letter + 5 = 4^th letter}

ORVA → (O + 3 = R), (R + 4 = V) & (V + 5 = A)

EHLQ → (E + 3 = H), (H + 4 = L) & (L + 5 = Q)

ILPU → (I + 3 = L), (L + 4 = P) & (P + 5 = U)

But,

KOSW → (K + 3 ≠ O), (O + 4 = S ) & (S + 5 ≠ W)

Hence, KOSW is the correct answer.

The numbers are written in the form of (n³+2)

345 → 7³ + 2 ⇒ 343 + 2 = 345

514 → 8³ + 2 ⇒ 512 + 2 = 514

218 → 6³ + 2 ⇒ 216 + 2 = 218

But,

733 → 9³ + 2 ⇒ 729 + 2 = 731 ≠ 733

Hence, 733 is the correct answer.

But,

In Geology, we study non-living things

Hence, "Geology" is the correct answer.

TAP : VDT → T + 2 = V, A + 3 = D & P + 4 = T ⇒ VDT

DRY : FUC → D + 2 = F, R + 3 = U & Y + 4 = C ⇒ FUC

RAT : TDX → R + 2 = T, A + 3 = D & T + 4 = X ⇒ TDX

But,

FRY : HTB → F + 2 = H, R + 3 = U & Y + 4 = C ⇒ HUC ≠ HTB

Hence, FRY : HTB is the correct answer.

But,

Psychiatrist deals with mental health

Hence, "Psychiatrist" is the correct answer.

The pattern followed here is :

{(1^st number)³ + 5} = 2^nd number

(9 : 734) → 9³ + 5 ⇒ 729 + 5 = 734

(7 : 348) → 7³ + 5 ⇒ 343 + 5 = 348

(5 : 130) → 5³ + 5 ⇒ 125 + 5 = 130

But,

(8 : 516) → 8³ + 5 ⇒ 512 + 5 = 517 ≠ 516

Hence, (8 : 516) is the correct answer.

All letters are arranged in alphabetical order

BDMS → B < D < M < S

HKPT → H < K < P < T

KMPV → K < M < P < V

But,

MIGF → M > I > G > F

Hence, MIGF is the correct answer.

73, 127 & 89 are prime numbers

But,

115 is not a prime number

Hence, 155 is the correct answer.
