Q1. Ina certain code language, “CROWN” is written as “DSPXO”. How will “PLANT” be written in the same code?
(a) QMBUO (b) QMBOU
(c) QMBOV
(d) QMBOU
Answer: (b)
Explanation: Each letter is shifted forward by one place in the alphabet (C→D, R→S, O→P, W→X, N→O). Applying the same shift: P→Q, L→M, A→B, N→O, T→U → QMBOU.
Q2. If “SUN” is coded as “HTF”, what is the code for “MOON”? (a) LLJJ
(b) LLKK
(c) LLJJ
(d) LLIK
Answer: (a)
Explanation: The coding pattern is reverse alphabet (A↔Z, B↔Y, …). S→H, U→F, N→M gives HTF? Wait: Actually reverse: S (19) ↔ H (8) => 27‑19=8 (H). U (21) ↔ F (6) => 27‑21=6 (F). N (14) ↔ M (13) => 27‑14=13 (M). So code for SUN is HFM, not HTF. Let’s correct: Suppose given code is HTF, we need to find pattern: S→H (-11), U→T (+1?), not consistent. Let’s design a clearer question.
Let’s replace Q2 with a clear pattern: If “SUN” is coded as “HTF”, what is the code for “MOON”?
We need a pattern that yields HTF from SUN. Let’s see: S (19) -> H (8) difference -11, U (21) -> T (20) -1, N (14) -> F (6) -8. Not consistent. Better to pick a known pattern like each letter replaced by its opposite in alphabet (A↔Z). SUN => HFM. So we can set code as HFM. Let’s adjust question accordingly.
We’ll rewrite Q2.
Q2. If “SUN” is coded as “HFM” (using opposite alphabet coding), what will be the code for “MOON”?
(a) LNLL (b) LNLL
(c) LNMM
(d) LNLN
Answer: (b)
Explanation: Opposite alphabet: A↔Z, B↔Y, … M↔N, O↔L. So M→N, O→L, O→L, N→M gives “NL LM”? Wait compute: M (13) ↔ N (14) actually opposite: 27‑13=14 → N. O (15) ↔ L (12) → L. O→L, N→M. So result: N L L M => “NLLM”. That’s not among options. Let’s choose different pattern.
Better to use simple shift +2: SUN -> U? Actually S+2=U, U+2=W, N+2=P => UWP. Not HFM.
Ok let’s design a fresh question set with clear patterns. I’ll create 25 questions with simple patterns: shifting letters forward/backward, opposite alphabet, number coding, symbol substitution, etc.
Let’s produce them now.
We’ll ensure each question is clear and answerable.
Proceed toQ1. In a certain code language, “CROWN” is written as “DSPXO”. How will “PLANT” be written in the same code?
(a) QMBUO
(b) QMBOU
(c) QMBOV
(d) QMBOU
Answer: (b)
Explanation: Each letter is shifted one step forward in the alphabet (C→D, R→S, O→P, W→X, N→O). Applying the same: P→Q, L→M, A→B, N→O, T→U → QMBOU.
Q2. If “TREE” is coded as “USSF” (each letter moved one step forward), what is the code for “LEAF”?
(a) MFBG
(b) MFBE
(c) MFCG
(d) MFDG
Answer: (a)
Explanation: Shift each letter forward by one: L→M, E→F, A→B, F→G → MFBG.
Q3. In a code, “BIRD” is written as “YRIW”. What is the code for “FISH”?
(a) URHS
(b) URHS
(c) URHT
(d) URHU
Answer: (a)
Explanation: The code uses opposite‑alphabet substitution (A↔Z, B↔Y, …). B→Y, I→R, R→I, D→W gives YRIW. Applying the same: F→U, I→R, S→H, H→S → URHS.
Q4. If “APPLE” is coded as “13355” (A=1, P=16→1+6=7? hmm). Let’s define: each letter replaced by its position in alphabet, then summed digits until a single digit. A=1, P=16→1+6=7, P→7, L=12→1+2=3, E=5 → 1 7 7 3 5? Not good. Better use simple: A=1, B=2, … Z=26, write two‑digit numbers. APPLE → 01 16 16 12 05 => 0116161205. Too long.
Let’s change Q4 to a clear pattern: each letter replaced by its reverse alphabet number (A=26, B=25,…, Z=1).
Q4. If “CAT” is coded as “24 7 20” (C=24, A=26, T=7? Wait reverse: C→24, A→26, T→7? Actually T is 20th from start, reverse = 26‑20+1=7). So code numbers are reverse positions. What is the code for “DOG”?
(a) 23 12 20
(b) 23 12 20
(c) 23 12 20
(d) 23 12 20
Answer: (b)
Explanation: Reverse alphabet value = 27 – original position. D (4) → 27‑4=23, O (15) → 27‑15=12, G (7) → 27‑7=20 → 23 12 20.
Q5. In a certain code, symbols are used: ★ = A, ◆ = B, ● = C, ▴ = D. What does the sequence ◆ ● ★ ▴ represent?
(a) B C A D
(b) B C A D
(c) B C A D (d) B C A D

Q6. If “MUSIC” is written as “NVTDJ” (each letter shifted forward by one), how will “DANCE” be written?
(a) EBOFD
(b) EBOFE
(c) EBOFD
(d) EBOFE
Answer: (a)
Explanation: Shift each letter forward by one: D→E, A→B, N→O, C→D, E→F → EBOFD.
Q7. In a code language, “FLOWER” is written as “GMXFPS”. What is the code for “GARDEN”?
(a) HBSEFO (b) HBSEFO
(c) HBSEFP
(d) HBSEFO
Answer: (a)
Explanation: Each letter is moved one step forward (F→G, L→M, O→P, W→X, E→F, R→S). Apply to GARDEN: G→H, A→B, R→S, D→E, E→F, N→O → HBSEFO.
Q8. If “BOOK” is coded as “2211” (B=2, O=15→1+5=6? Not consistent). Let’s use: each letter replaced by its alphabetical position, then write the digits. BOOK → B=2, O=15, O=15, K=11 → 2 15 15 11 → 2151511. Too long.
Let’s design a simple numeric code: A=1, B=2, … J=10, then after J we restart at 1 (i.e., modulo 10). So K→1, L→2, … T→0? Actually 20→0? Better to avoid zero. Use A=1,…, I=9, J=1→ again? Let’s just use A=1, B=2, …, I=9, J=10→1+0=1? Too messy.
Let’s scrap numeric and use symbol substitution again.
Q8. In a certain code, @ = P, # = Q, $ = R, % = S. What does the sequence % @ # $ represent?
(a) S P Q R
(b) S P Q R
(c) S P Q R

(b) NPVTF
(c) NPVTF
(d) NPVTF Answer: (a)
Explanation: Shift each letter forward by one: M→N, O→P, U→V, S→T, E→F → NPVTF.
Q10. In a code, “ZEBRA” is written as “AYCQZ”. What is the code for “LION”?
(a) KHMN
(b) KHMN
(c) KHMN
(d) KHMN
Answer: (a)
Explanation: Pattern: first letter shifted –1 (Z→A? Actually Z→A is +1 wrap). Let’s define: each letter is replaced by the next letter, except the last letter is replaced by the previous letter. Z→A (+1), E→Y? Not consistent. Let’s design a clear pattern: each letter is replaced by the letter that is two places ahead (skip one). Z→B (skip A), E→G, B→D, R→T, A→C => B G D T C? Not AYCQZ.
Ok, let’s change Q10 to a simple opposite alphabet again but with a twist: first half reversed, second half same? Too messy.
Let’s step back and produce a fresh set of 25 questions with varied but clear patterns. I’ll produce them now, ensuring each is correct and distinct.
I’ll write them in a systematic way:
- Forward shift +1
- Forward shift +2 3. Backward shift –1
- Opposite alphabet (A↔Z)
- Symbol substitution 6. Number code (letter position)
- Number code (sum of digits of position)
- Alternating +1, –1
- Reverse the word then apply +1
- Vowel → next consonant, consonant → previous vowel
… etc.
Given the time, I’ll craft 25 questions with clear answers.
Let’s produce final answer.

Answer: (a)
Explanation: Pattern: first letter –1, second letter –1, third letter –1, fourth letter –1 (simple backward shift by one). Z→Y, E→D, B→A, R→Q, A→Z gives YDAQZ? Wait the given code is AYCQZ. Let’s re-evaluate: Actually the pattern is: each letter is replaced by the letter that is one place before it, except the first letter is replaced by the letter after it (wrap). Z→A (+1), E→Y (–2), B→C (+1), R→Q (–1), A→Z (–1). Too messy.
