Odd One Out (SSC CHSL 2020 Tier – 1)

The pattern followed here is :

{1^st letter - 5 = 2^nd letter}, {2^nd letter - 7 = 3^rd letter}, {3^rd letter + 11 = 4^th letter} & {4^th letter + 13 = 5^th letter}

IDWHU → (I - 5 = D), (D - 7 = W), (W + 11 = H) & (H + 13 = U)

UPITG → (U - 5 = P), (P - 7 = I), (I + 11 = T) & (T + 13 = G)

CXQBO → (C - 5 = X), (X - 7 = Q), (Q + 11 = B) & (B + 13 = O)

But,

EZSFV → (E - 5 = Z), (Z - 7 = S), (S + 11 = F) & (F + 13 ≠ V)

Hence, EZSFV is the correct answer.

The pattern followed here is :

(1^st number ÷ 2)² = 2^nd number

(30 : 225) → (30 ÷ 2)² ⇒ 15² = 225

(20 : 100) → (20 ÷ 2)² ⇒ 10² = 100

(14 : 49) → (14 ÷ 2)² ⇒ 7² = 49

But,

(24 : 130) → (24 ÷ 2)² ⇒ 12² = 144 ≠ 130

Hence, (24 : 130) is the correct answer.

The pattern followed here is :

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

EBCD → (E - 3 = B), (B + 1 = C) & (C + 1 = D)

NKLM → (N - 3 = K), (K + 1 = L) & (L + 1 = M)

IFGH → (I - 3 = F), (F + 1 = G) & (G + 1 = H)

But,

WXYZ → (W - 3 ≠ X), (X + 1 = Y) & (Y + 1 = Z)

Hence, WXYZ is the correct answer.

The pattern followed here is :

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

DZHW → (D - 4 = Z), (D + 4 = H) & (D ↔ W)

GCKT → (G - 4 = C), (G + 4 = K) & (G ↔ T)

HDLS → (H - 4 = H), (H + 4 = L) & (H ↔ S)

But,

PLSK → (P - 4 = L), (P + 4 ≠ S) & (P ↔ K)

Hence, PLSK is the correct answer.

The pattern followed here is :

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

(4 : 48) → (4³ - 4²) ⇒ 64 - 16 = 48

(7 : 294) → (7³ - 7²) ⇒ 343 - 49 = 294

(6 : 180) → (6³ - 6²) ⇒ 216 - 36 = 180

But,

(5 : 105) → (5³ - 5²) ⇒ 125 - 25 = 100 ≠ 105

Hence, (5 : 105) is the correct answer.

The pattern followed here is :

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

WBYT → (W + 5 = B), (B ↔ Y) & (Y - 5 = T)

YDWR → (Y + 5 = D), (D ↔ W) & (W - 5 = R)

CHSN → (C + 5 = H), (H ↔ S) & (S - 5 = N)

But,

MRGB → (M + 5 = R), (R ↔ I ≠ G) & (G - 5 = B)

Hence, MRGB is the correct answer.

The pattern followed here is :

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

HNTZ → (H + 6 = N), (N + 6 = T) & (T + 6 = Z)

AGMS → (A + 6 = G), (G + 6 = M) & (M + 6 = S)

VBHN → (V + 6 = B), (B + 6 = H) & (H + 6 = N)

But,

IPVA → (I + 6 ≠ P), (P + 6 = V) & (V + 6 ≠ A)

Hence, IPVA is the correct answer.
