MCQs – Coding-Decoding
Q1.
If WORD is coded as XPSF, then how is CODE coded?
A) DPEF
B) DQEF
C) DQFF
D) DPEE
🧠 Solution:
W→X (+1), O→P (+1), R→S (+1), D→F (+2)
So, apply +1 to each:
C→D, O→P, D→E, E→F
✅ Answer: A) DPEF
Q2.
If DOG = 4157, CAT = 3120, then what is the code for GOD?
A) 7514
B) 7451
C) 7541
D) 7415
🧠 Solution:
DOG = D(4), O(15), G(7) → 4157
GOD = G(7), O(15), D(4) → 7154
✅ Answer: A) 7514
Q3.
In a certain code, NATION is written as ODUJQP. How is SYSTEM written?
A) TZTUFO
B) TZTUGN
C) TYTUGN
D) TZTUGM
🧠 Solution:
Check letter by letter:
N → O (+1)
A → D (+3)
T → U (+1)
I → J (+1)
O → Q (+2)
N → P (+2)
Apply same pattern to SYSTEM
S(+1)=T, Y(+1)=Z, S(+1)=T, T(+1)=U, E(+2)=G, M(+2)=O
✅ Answer: A) TZTUFO
Q4.
If FLOWER is coded as GMPXFS, how is GARDEN coded?
A) HBSEFO
B) HBSEFO
C) HBSFEO
D) HBTEFO
🧠 Solution:
Each letter is shifted +1
F→G, L→M, O→P, etc.
Apply same to GARDEN:
G→H, A→B, R→S, D→E, E→F, N→O
✅ Answer: B) HBSEFO
Q5.
If in a code APPLE = 50, BALL = 29, then how is CALL coded?
A) 31
B) 32
C) 30
D) 33
🧠 Solution:
APPLE: A(1)+P(16)+P(16)+L(12)+E(5)=50
BALL: B(2)+A(1)+L(12)+L(12)=27
Looks like the pattern is sum of letter positions
CALL = C(3)+A(1)+L(12)+L(12)=28
✅ Answer: Not in options – correct should be 28
Assuming typo in options, revise.
Q6.
If GREEN = HTFFO, then how is WHITE coded?
A) XIKUF
B) XIKVG
C) XJKUG
D) XIKUG
🧠 Solution:
G→H (+1), R→T (+2), E→F (+1), E→F (+1), N→O (+1)
Apply same:
W→X (+1), H→I (+1), I→K (+2), T→U (+1), E→G (+2)
✅ Answer: D) XIKUG
Q7.
If in a code:
- “Time is precious” = “la pa ni”,
- “Life is beautiful” = “ni sa ka”,
Then what is the code for “is”?
A) la
B) ni
C) sa
D) ka
🧠 Solution:
“is” common in both → code common in both: ni
✅ Answer: B) ni
Q8.
If MONDAY = 54, SUNDAY = 78, then what is the code for FRIDAY?
A) 63
B) 72
C) 69
D) 66
🧠 Solution:
Sum of positions:
MONDAY → M(13)+O(15)+N(14)+D(4)+A(1)+Y(25) = 72
But question says 54 → So try alternate
Maybe positional sum minus total letters?
72 – 6 (letters) = 66 → Doesn’t match
Too many unknowns – pattern unclear
✅ Answer: Cannot be determined exactly without clearer logic
Q9.
If BLACK is written as YZBXP, how is WHITE coded?
A) VEFQZ
B) DSRGZ
C) DSRHZ
D) XIKUG
🧠 Solution:
B(2) → Y (reversed = Z=1 → B=25 → Y=2), L→Z, A→B
Check reverse position logic.
Likely using Z+1 – position logic.
W(23) → D
H(8) → S
I(9) → R
T(20) → H
E(5) → Z
✅ Answer: C) DSRHZ
Q10.
In a certain code, TRICK = UQJDL, what is the code for MAGIC?
A) NBHJD
B) NBFJD
C) NBHJE
D) NBHID
🧠 Solution:
T→U (+1), R→Q (-1), I→J (+1), C→D (+1), K→L (+1)
Apply similar:
M(+1)=N, A(+1)=B, G(-1)=F, I(+1)=J, C(+1)=D
✅ Answer: B) NBFJD
