Q. If 35796 = 44887, then 46823 = ?

Option: (A) 57914   (B) 55914   (C) 55714   (D) 55934

Solⁿ

$$35796\to 44887$$

Pattern: (+1, −1, +1, −1, +1),

$$4+1=5\; /$$

Ans: (B) 55914

1. In a certain code language: ‘678’ means ‘How are you’  ‘347’ means ‘How is life’ ‘569’ means ‘You were wonderful’ Which number is used for ‘You’?

Options: (1) 6  (2) 3  (3) 4   (4) 7   (5) None of these

Solⁿ

      Compare ‘678’ - How are you and ‘347’ - How is life - Common word = How, Common number = 7, 7 = How

      Now in ‘678’, remaining numbers 6, 8 represent are / you

      Compare ‘678’ (How are you) and ‘569’ (You were wonderful)

 Common word = You, Common number = 6, You = 6, Ans: 6

TRICK: Common Word – Common Number Rule. Find the common word in the given meanings > Find the common number in the given codes > Common word = Common number

2. In a certain code language: ‘526’ means ‘Sky is blue’ ‘24’ means ‘Blue colour’ ‘436’ means ‘Colour is fun’ Which number is used for ‘fun’?

Options: (1) 3   (2) 6   (3) 5   (4) 4

Solⁿ

Find common word & common number: 526 → Sky is blue, 24 → Blue colour

Common word Blue → common number 2, So, 2 = Blue

2. Fix the next common pair: 24 → Blue colour, 436 → Colour is fun

Common word Colour → common number 4, So, 4 = Colour

3. Find the common word again: 526 → Sky is blue, 436 → Colour is fun

Common word is → common number 6, So, 6 = is

Remaining number = fun: In 436, numbers are 4, 3, 6, 4 = Colour, 6 = is

Remaining 3 = fun, Ans: 3

3. In a certain code language: ‘123’ means ‘Hot filtered coffee’ ‘356’ means ‘Very hot day’ ‘589’ means ‘Day and night’

   Which number is used for ‘very’?

Options: (1) 5  (2) 6  (3) 8  (4) 9  (5) 2

Solⁿ

Compare ‘123’ (Hot filtered coffee) and ‘356’ (Very hot day) → Common word = Hot, Common number = 3, 3 = Hot

  Compare ‘356’ (Very hot day) and ‘589’ (Day and night)→ Common word = Day, Common number = 5, 5 = Day

  Now look at ‘356’ = Very hot day→ Numbers: 3, 5, 6, 3 = Hot, 5 = Day, Remaining number 6 = Very

Ans: 6

Exam Trick: Find common words → match common numbers → the leftover number gives the answer.

Q) QPRS : TUWV :: JIKL : ?

Options: A. NMOP  B. NMPO  C. MNPO  D. MNOP

Solⁿ / সমাধান

QPRS → TUWV

Q (+3) → T , P (+5) → U , R (+5) → W , S (+3) → V

JIKL → ?

J (+3) → M , I (+5) → N , K (+5) → P , L (+3) → O

⇒ JIKL → MNPO

Ans: (C) MNPO

==========================================

Q) FL: BH :: RY : NU :: GM : ?

Options: A) CI  B) CL  C) CP  D) DI

Observe the pattern:

• FL → BH : [F → B (−4), L → H (−4)]


• RY → NU : [ R → N (−4), Y → U (−4)]

So, the rule is: Each letter is shifted 4 places backward in the alphabet.  (প্ৰতিটো আখৰ বৰ্ণমালাত 4 স্থান পিছলৈ সৰোৱা হৈছে।)

Now apply the same rule to GM: [G → C (−4), M → I (−4)]

Therefore, GM → CI

Q) BNLP : YMOK :: KGDU : ?

Options: A) PTXG  B) PTWF  C) QUWF  D) QUXG

Solⁿ / সমাধান

Observe the first pair: BNLP → YMOK

Using opposite letters (A ↔ Z, B ↔ Y, C ↔ X, ...)

 Letter : Opposite: B ↔ Y, N ↔ M, L ↔ O, P ↔ K

So, BNLP → YMOK

Now apply the same rule to KGDU:

 Letter : Opposite: K ↔ P, G ↔ T, D ↔ W, U ↔ F

Ans: B) PTWF

Use the Reverse Alphabet Rule: A ↔ Z, B ↔ Y, C ↔ X, D ↔ W, E ↔ V, F ↔ U, G ↔ T, H ↔ S, I ↔ R, J ↔ Q, K ↔ P, L ↔ O, M ↔ N

KGDU ⇒ K→P, G→T, D→W, U→F ⇒ PTWF

Q) SLIP = 208, DICE = 348 RICE = ? Option: A 192 B 292 C287 D 176

Soln : Let's use reverse alphabetical values: Reverse value = 27 − Alphabet Position

• Normal: a, b, c, d, e, f, g, h, i, j, k, l, m, n, o, p, q, r, s, t, u, v, w, x, y, z


• Reverse: z, y, x, w, v, u, t, s, r, q, p, o, n, m, l, k, j, i, h, g, f, e, d, c, b, a

Check SLIP: S = 8, L = 15, I = 18, P = 11

Sum = 8 + 15 + 18 + 11 = 52

52 × 4 = 208

Check DICE: D = 23, I = 18, C = 24, E = 22

Sum = 23 + 18 + 24 + 22 = 87

87 × 4 = 348

Find RICE : R = 9, I = 18, C = 24, E = 22

Sum = 9 + 18 + 24 + 22 = 73

73 × 4 = 292

Ans: (B) 292

Q. FIGHT = 45 , VENT = 57 , TREND = ?

Option : A. 62 , B. 71 C. 56 , D. 43

Soln

FIGHT = 45

VENT = 57

TREND = ?

Ans :

FIGHT = 45

F - 6, I - 9, G -7, H - 8, T - 20

6+9+7+8+20 = 50

50-5 = 45 , Substract nos of alphabet in the word.

VENT = 57

V - 22, E - 5, N - 14, T - 20

22+5+14+20 = 61

61-4 = 57 , Substract nos of alphabet in the word.

TREND = ?

T- 20, R - 18, E - 5, N - 14, D - 4

20+18+5+14+4 = 61

61-5 = 56 , Substract nos of alphabet in the word.

Q. In a code language : CAR = 234 FAT = 256 to C = 468 then 'F' = ?  (A) 6 (B) 2 (C) 5 (4D) 4

Reason: In the code FAT = 256, the first digit corresponds to F,so F = 2.

Ans: 2
