Odd One Out (Varieties Questions)

DOL ⇒ { O and L are opposite to each other} and {D + 8 = L}

MIP ⇒ {I and P are not opposite to each other} and {M + 8 ≠ U) {not follows}

ARI ⇒ {R and I are opposite to each other) and {A + 8 = I}

NEV ⇒ {E and V are opposite to each other} and {N + 8 = V}

LNSV ⇒ L + 2 = N, N + 5 = S, S + 3 = V
FHMP ⇒ F + 2 = H, H + 5 = M, M + 3 = P
BDIL ⇒ B + 2 = D, D + 5 = I, I + 3 = L
JLPT ⇒ J + 2 = L, L + 5 ≠ P, P + 3 ≠ T (not follows)

Hence, JLPT is the correct answer.

[(1^st number + 1) ÷ 2]² = 2^nd number

(29 : 225) → {(29 + 1) ÷ 2}² ⇒ (30 ÷ 2)² ⇒ (15)² = 225

(17 : 81) → {(17 + 1) ÷ 2}² ⇒ (18 ÷ 2)² ⇒ (9)² = 81

(45 : 576) → {(45 + 1) ÷ 2}² ⇒ (46 ÷ 2)² ⇒ (23)² ≠ 576

(31 : 256) → {(31 + 1) ÷ 2}² ⇒ (32 ÷ 2)² ⇒ (16)² = 256

Clearly, we can see that (45 : 576) is an odd one.

(1^st number)³ + (1^st number)² = (2^nd number)

(7 : 392) → (7³ + 7²) = 392

(9 : 810) → (9³ + 9²) = 810

(15 : 3150) → (15³ + 15²) ≠ 3150 (not follow)

(12 : 1872) → (12³ + 12²) = 1872

Clearly, we can see that (15 : 3150) is an odd one.

(First term × 2.5) - (First term - 10) = Second term

(13 : 28.5) → (13 × 2.5) - (13 - 10) ≠ 28.5 (not follow)

(15 : 32.5) → (15 × 2.5) - (15 - 10) = 32.5

(19 : 38.5) → (19 × 2.5) - (19 - 10) = 38.5

(17 : 35.5) → (17 × 2.5) - (17 - 10) = 35.5

Clearly, we can see that (13 : 28.5) is an odd one.

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

(4 : 48) → (4³ - 4²) = 48

(6 : 180) → (6³ - 6²) = 180

(8 : 448) → (8³ - 8²) = 448

(9 : 639) → (9³ - 9²) ≠ 639

Hence, (9 : 639) is the correct option.

(First number)² = (Second number)

(15 : 225) → (15)² = 225

(13 : 169) → (13)² = 169

(12 : 144) → (12)² = 144

(21 : 431) → (21)² = 441 ≠ 431

Hence, (21 : 431) is the correct option.

Sum of numerical position of 1st and 4th letter is equal to 2nd and 3rd letter in alphabet.

LRPV → L + V ⇒ 12 + 22 = 34,  R + P ⇒ 18 + 16 = 34

SYGM → S + M ⇒ 19 + 13 = 32, Y + G ⇒ 25 + 7 = 32

DBJH → D + H ⇒ 4 + 8 = 12, B + J ⇒ 2 + 10 = 12

CNDV → C + V ⇒ 3 + 22 = 25, N + D ⇒ 14 + 4 = 18

Clearly, we can see that CNDV is an odd one.

Or,

LRPV → 12 + 18 + 16 + 22 = 68 (even)

SYGM → 19 + 25 + 7 + 13 = 64 (even)

DBJH → 4 + 2 + 10 + 8 = 24 (even)

CNDV → 3 + 14 + 4 + 22 = 43 (odd)

(Product of digit of third number)(Product of digit of first number)

3 × 3 = (9), 3 × 8 = (24) ⇒ 924
9 × 6 = (54), 5 × 5 = (25) ⇒ 5425
6 × 7 = (42), 2 × 3 = (6) ⇒ 426

But in option (c) this pattern is not followed.
3 × 2 = (6), 4 × 3 = (12) ⇒ 612 ≠ 126
