Coding Questions and Answers
Q1: If the word "MADRAS" is coded as "NBESBT" in a certain language, how would "BOMBAY" be coded?
A. CPNCBX
B. CPNCBZ
C. CPOCBZ
D. CQOCBZ
Answer: B. CPNCBZ
Explanation:
Each letter in the word is shifted forward by one position in the English alphabet. Applying the same rule:
B → C, O → P, M → N, B → C, A → B, Y → Z
Thus, "BOMBAY" becomes "CPNCBZ."
Q2: If "CHAMPION" is coded as "HCMAIPNO," how would "NEGATIVE" be coded?
A. NEAGVEIT
B. ENAGITEV
C. MGAETVIE
D. EGAITEVN
Answer: B. ENAGITEV
Explanation:
The coding pattern swaps every two consecutive letters. Applying the same pattern to "NEGATIVE":
N → E, E → N, G → A, A → G, T → I, I → T, V → E
Thus, "NEGATIVE" becomes "ENAGITEV."
Q3: If "TEACHER" is written as "VGCEJGT" in a certain code, how would "DULLARD" be written?
A. FWMNCT
B. FWNNBTE
C. FWNNCSF
D. FWNNCTF
Answer: D. FWNNCTF
Explanation:
Each letter is moved two steps forward in the English alphabet:
D → F, U → W, L → N, L → N, A → C, R → T, D → F
Thus, "DULLARD" becomes "FWNNCTF."
Q4: If "PRABA" is coded as 27595 and "THILAK" as 368451, how would "BHARATHI" be coded?
A. 96575368
B. 57686535
C. 37536689
D. 96855368
Answer: A. 96575368
Explanation: Each letter is assigned a specific numerical code. Using the same assigned values, "BHARATHI" is coded as 96575368.
Q5: If "ROOM" is called "BED," "BED" is called "WINDOW," "WINDOW" is called "FLOWER," and "FLOWER" is called "COOLER," where would a man sleep?
A. WINDOW
B. BED
C. FLOWER
D. COOLER
Answer: A. WINDOW
Explanation: A man normally sleeps on a "BED," but since "BED" is called "WINDOW," the correct answer is "WINDOW."
Q6: In a certain code, "BLOCK" = 13 and "CURTAIN" = 27. What is the value of "SCIENCE"?
A. 32
B. 36
C. 38
D. 34
Answer: C. 38
Explanation: The sum of the place values of the letters is calculated using specific rules. Applying the same method, the value for "SCIENCE" is 38.
Q7: Given the coding scheme:
- "dumb monkeys are actors" → "la pa zi ta"
- "joker monkeys are dumb" → "pa zi la sa"
- "flower are red fool" → "na hi ga pa"
- "dumb pins and flower" → "zi mi jo ga"
What is the code for "dumb joker flower"?
A. zi la sa
B. zi sa ga
C. sa mi jo
D. pa zi mi
Answer: B. zi sa ga
Explanation:
- "dumb" → "zi"
- "joker" → "sa"
- "flower" → "ga"
Combining these, "dumb joker flower" is coded as "zi sa ga."
Q8: Using the same coding scheme as in Q7, what would be the code for "flower are fool"?
A. zi la sa
B. zi sa ga
C. sa mi jo
D. pa zi mi
E. None of these
Answer: E. None of these
Explanation:
- "flower" → "ga"
- "are" → "pa"
- "fool" → "na" or "hi"
So, the possible codes are "ga pa na" or "ga pa hi," neither of which is in the given options.
Q9: Using the same coding scheme, what does "pa" represent?
A. joker
B. flower
C. are
D. pins
Answer: C. are
Explanation: From multiple statements, "are" is consistently coded as "pa."
Q10: Which of the following phrases is coded as "na hi la" in the given language?
A. monkeys are fool
B. red fool monkeys
C. joker monkeys flower
D. red dumb flower
Answer: B. red fool monkeys
Explanation:
- "red fool" → "na hi"
- "monkeys" → "la"
Thus, "red fool monkeys" is coded as "na hi la."
Q11.
In a certain code language:
- ‘dumb monkeys are actors’ is coded as ‘la pa zi ta’
- ‘joker monkeys are dumb’ is coded as ‘pa zi la sa’
- ‘flower are red fool’ is coded as ‘na hi ga pa’
- ‘dumb pins and flower’ is coded as ‘zi mi jo ga’
What does the code ‘la’ stand for?
Options:
A) monkeys
B) flower
C) joker
D) fool
Answer:
✅ monkeys
Explanation:
From the given statements:
- ‘dumb monkeys are actors’ → ‘la pa zi ta’
- ‘joker monkeys are dumb’ → ‘pa zi la sa’
The common words in both statements are "monkeys" and "dumb", and their corresponding common codes are ‘la’ and ‘zi’.
In the third and fourth statements, "dumb" appears again in ‘zi’, confirming that ‘la’ represents ‘monkeys’.
Q12.
In a certain code language:
- ‘Tom Kun Sud’ means “Dogs are barking”
- ‘Kun Jo Mop’ means “Dogs and Horses”
- ‘Mut Tom Ko’ means “Donkeys are mad”
Which word in this language stands for ‘barking’?
Options:
A) Sud
B) Kun
C) Jo
D) Tom
Answer:
✅ Sud
Explanation:
- In the first and second statements, the common word is “Dogs”, and the common code is ‘Kun’.
- In the first and third statements, the common word is “are”, and the common code is ‘Tom’.
- The remaining word “barking” in the first statement must correspond to ‘Sud’.
Q13.
In a certain code language, letters are shifted one position forward in the alphabet:
- A → B, B → C, C → D, etc.
How will SMART be written in that code?
Options:
A) TLBSU
B) SHBSU
C) TNBSU
D) SNBRU
Answer:
✅ TNBSU
Explanation:
By shifting each letter one step forward:
- S → T, M → N, A → B, R → S, T → U.
- Thus, SMART is encoded as TNBSU.
Q14.
In a certain code language:
- ‘851’ means ‘good sweet fruit’
- ‘783’ means ‘good red rose’
- ‘341’ means ‘rose and fruit’
Which digit represents ‘sweet’ in this code?
Options:
A) 8
B) 5
C) 1
D) 3
Answer:
✅ 5
Explanation:
- From the first and second statements, the common word “good” corresponds to the common digit ‘8’.
- From the first and third statements, the common word “fruit” corresponds to ‘1’.
- The remaining word “sweet” in the first statement must correspond to ‘5’.
Q15.
Using the same coded language from Q14, which digit represents ‘good’?
Options:
A) 8
B) 5
C) 1
D) 3
Answer:
✅ 8
Explanation:
From:
- ‘851’ = “good sweet fruit”
- ‘783’ = “good red rose”
The common word “good” appears in both statements, and the common digit is ‘8’. Thus, ‘8’ represents ‘good’.
