3. 7*9*10 = 8 , 9*11*30 = 5 , 11*17*21 =13 , 23*4*15 = ?

Rule: Add all three numbers → then add digits (tens + units) 

নিয়ম: সকলো সংখ্যা যোগ কৰক → তাৰ পিছত দশক + একক যোগ কৰক

Explanation

7 + 9 + 10 = 26 → 2 + 6 = 8
9 + 11 + 30 = 50 → 5 + 0 = 5
11 + 17 + 21 = 49 → 4 + 9 = 13

Now: 23 + 4 + 15 = 42 → 4 + 2 = 6

Ans: 6

Options: A) 56139537853  B) 56149512965  C) 56141956578  D) 5614921695

Explanation

Rule: Each letter → Alphabet position → Digit sum (if needed) (Alphabet position লৈ digit sum কৰিলে → 56149512965)

From MOBILITY: M(13) = 4, O(15) = 6, B(2) = 2, I(9) = 9, L(12) = 3, I(9) = 9, T(20) = 2, Y(25) = 7 , 46293927

8. If FAN = 21–26–13, then DEAS = ?

Explanation:

Rule: Each letter → Opposite alphabet position
Formula: 27 − position

Check: F(6) → 27 - 6 = 21, A(1) → 27 - 1 = 26, N(14) → 27 - 14 = 13

Now apply to DEAS: D(4) → 27 - 4 = 23, E(5) → 27 - 5 = 22, A(1) → 27 - 1 = 26, S(19) → 27 - 19 = 8

Option: (a) BKMCL (b) СМКСМ C) AKMCL (d) AKKMCL

Rule: Fill the blanks so the whole series looks like a smooth A–Z sequence (forward or slight backward).

Explanation:

In this question:

• Given letters already follow parts like: AB, K → M


• So we fill missing letters to maintain alphabet continuity

Missing letters: A K M C L

Ans: (c) AKMCL

Trick: “Always complete the alphabet pattern, not individual parts.”

10. If ROSE = TQUG and BISCUIT = ?

Option : (a) GJTDVJU (b) DEVEWKV (c) DKUEWKY (d) DKUEWKV

Explanation: In the given question, ROSE = TQUG, each letter is shifted 2 steps forward in the alphabet (R→T, O→Q, S→U, E→G). So, the same rule is applied to BISCUIT. Each letter moves 2 positions ahead: B→D, I→K, S→U, C→E, U→W, I→K, T→V. After applying this pattern, we get the new word DKUEWKV. Therefore, the correct answer is (d) DKUEWKV.

এই প্ৰশ্নটোত ROSE = TQUG, অৰ্থাৎ প্ৰতিটো আখৰক ২টা স্থান আগলৈ সলোৱা হৈছে (R→T, O→Q, S→U, E→G)। একেই নিয়ম BISCUIT ত প্ৰয়োগ কৰা হয়। প্ৰতিটো আখৰ ২টা স্থান আগলৈ যায়: B→D, I→K, S→U, C→E, U→W, I→K, T→V। এইদৰে সলোৱাৰ পিছত নতুন শব্দ হয় DKUEWKV। সেয়ে সঠিক উত্তৰ হৈছে (d) DKUEWKV।

5. If HAND = JCPF, then LEG = ?

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

11. NUMBER : UNBMRE :: GHOSTS : ?

Option: A. HGOSTS B. HGSOST C. HOGSTS D. HGSOTS

Explanation: In NUMBER → UNBMRE, the letters are rearranged by first splitting the word into pairs: NU MB ER, and then reversing each pair to get UN BM RE. The same rule is applied to GHOSTS. First, split it into pairs: GH OS TS, then reverse each pair to get HG SO ST. When we combine these, the final word becomes HGSOST. Therefore, the correct answer is (B) HGSOST.

NUMBER → UNBMRE ত শব্দটো প্ৰথমে জোৰা (pair) হিচাপে ভঙা হৈছে: NU MB ER, তাৰ পিছত প্ৰতিটো জোৰা উলটাই দিয়া হৈছে: UN BM RE। একেই নিয়ম GHOSTS ত প্ৰয়োগ কৰা হৈছে। প্ৰথমে জোৰা কৰা হৈছে: GH OS TS, তাৰ পিছত উলটাই দিলে হয় HG SO ST। এইবোৰ একেলগে লিখিলে পোৱা যায় HGSOST। সেয়ে সঠিক উত্তৰ হৈছে (B) HGSOST।

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

12. MENTAL = LNDFMOSUZBKM Find: TEST = ?

Option: A. UVFGTUU B. RSCDQRRS C. SUDFQRSU D. SUDFRTSU

Explanation: In the given code, MENTAL = LNDFMOSUZBKM, each letter is converted into two letters, so the total number of letters becomes double. For example, M becomes LN, E becomes DF, N becomes MO, T becomes SU, A becomes ZB, and L becomes KM. This shows that each letter is changed into a pair by shifting one step backward and one step forward in the alphabet. Applying the same rule to TEST, we convert each letter: T becomes SU, E becomes DF, S becomes QR, and T becomes SU. When we combine all these pairs, we get SUDFQRSU. Therefore, the correct answer is (C) SUDFQRSU.

এই প্ৰশ্নটোত MENTAL = LNDFMOSUZBKM বুলি দিয়া আছে, ইয়াত প্ৰতিটো আখৰক দুটা আখৰত পৰিবৰ্তন কৰা হৈছে, অৰ্থাৎ মোট আখৰ সংখ্যা দুগুণ হৈছে। উদাহৰণস্বৰূপে, M → LN, E → DF, N → MO, T → SU, A → ZB, L → KM। ইয়াৰ পৰা বুজা যায় যে প্ৰতিটো আখৰক এটা পিছলৈ আৰু এটা আগলৈ সলাই নতুন দুটা আখৰ বনোৱা হৈছে। এতিয়া একে নিয়ম TEST ত প্ৰয়োগ কৰিলে: T → SU, E → DF, S → QR, T → SU। এইবোৰ একেলগে লিখিলে পোৱা যায় SUDFQRSU। সেয়ে সঠিক উত্তৰ হৈছে (C) SUDFQRSU।

13. ACCE : EGGI :: IKKM : ?

Option: A. MOOQ B. NOOP C. MPPQ D. NPPR

Apply the same rule to IKKM: I→M, K→O, K→O, M→Q, So, we get MOOQ

Ans: (A) MOOQ

ব্যাখ্যা: ACCE → EGGI ত প্ৰতিটো আখৰক ৪টা স্থান আগলৈ সলোৱা হৈছে: A→E, C→G, C→G, E→I

14. 24a6d4b9c8 = ?

If a = ÷,  b = +,  c = - , d = x

Option a. 2,  b = 17,  c=34,  d=19

Ans:17

Explanation: In the given expression 24 a 6 d 4 b 9 c 8, the symbols are replaced as a = ÷, b = +, c = −, d = ×, so the expression becomes 24 ÷ 6 × 4 + 9 − 8. According to the BODMAS rule, we first perform division and multiplication from left to right: 24 ÷ 6 = 4, then 4 × 4 = 16. After that, we do addition and subtraction: 16 + 9 = 25, and 25 − 8 = 17. Therefore, the final answer is 17.

ব্যাখ্যা: ই প্ৰশ্নটোত 24 a 6 d 4 b 9 c 8 ত দিয়া আছে, য’ত a = ÷, b = +, c = −, d = ×। সেয়ে এক্সপ্ৰেছনটো হয় 24 ÷ 6 × 4 + 9 − 8। BODMAS নিয়ম অনুসৰি প্ৰথমে ভাগ আৰু গুণ বাওঁফালৰ পৰা কৰা হয়: 24 ÷ 6 = 4, তাৰ পিছত 4 × 4 = 16। তাৰ পিছত যোগ আৰু বিয়োগ কৰা হয়: 16 + 9 = 25, আৰু 25 − 8 = 17। সেয়ে শেষ উত্তৰ হৈছে 17।

Practice Questions:

1. 18 a 3 b 6 c 2 (a = ÷, b = ×, c = +)


2. 20 a 5 d 2 b 8 c 3
