LR - Coding Decoding - Previous Year CAT/MBA Questions
You can practice all previous year OMET questions from the topic LR - Coding Decoding. This will help you understand the type of questions asked in OMET. It would be best if you clear your concepts before you practice previous year OMET questions.
What does ‘orange’ represent in a code language?
I. ‘rim pa xab’ means ‘orange and apple’ in that code language
II. ‘na pie tac’ means ‘I dislike sweet’ in that code language
III. ‘na tsi pa’ means ‘orange is sweet’ in that code language
- A.
All I, II and III
- B.
Only II and III
- C.
Only I and III
- D.
Only I and either II or III
Answer: Option C
Explanation :
Observe that the word ‘orange’ is present only in statements I and III. Also, there is no other word that is common to both statements I and III. So, if you consider the only code that is common to both statements I and III, the code for orange can be found.
Hence, only statements I and III are sufficient to answer the question.
Hence, option 3.
Note: The code for ‘orange’ is “pa”; but you need not find this.
Workspace:
In the question below, three incomplete rows of letters/numerals are given which correspond to each other in some way. Find the letters/numerals which come in the vacant places marked by “?”
- A.
a, c, d, d
- B.
d, a, c, c
- C.
c, a, d, d
- D.
d, c, a, a
Answer: Option D
Explanation :
The first row has uppercase letters, the second has digits and the third has lowercase letters.
Use terms common to rows to identify the relation between these three groups.
From first two rows: C = 1; and from last two rows: 1 = a i.e. C = 1 = a
Hence, the required term i.e. BDCC corresponds to _ _ aa.
Hence, option 4.
Note: It can be verified that B = 2 = d and D = 4 = c (as A = 3)

Given below are some words from an artificial language.
agnoscrenia means poisonous spider
delanocrenia means poisonous snake
agnosdeery means brown spider
Which of the following is most likely to mean “black widow spider”?
- A.
aeeryclostangus
- B.
agnosvitriblunin
- C.
agnosdelano
- D.
trymuttiangus
Answer: Option B
Explanation :
agnoscrenia means poisonous spider and agnosdeery means brown spider. Thus, the common term between them is agnos, which means spider.
Thus, options 1 and 4 are eliminated.
Agnoscrenia means poisonous spider and delanocrenia means poisonous snake. Thus, the common term between them is crenia, meaning poisonous.
Therefore, delano means snake.
Hence option 3 is also eliminated.
Therefore, black widow spider can mean agnosvitriblunin.
Hence, option 2.

Here are some words translated from an artificial language.
dionot means oak tree
blyonot means oak leaf
blycrin means maple leaf
Which word could mean “maple syrup”
- A.
blymuth
- B.
hupponot
- C.
patricrin
- D.
crinweel
Answer: Option C
Explanation :
From the first two statements, we can infer that ‘onot’ means ‘oak’. Note that ‘onot’ is in the second half of the word in the artificial language but ‘oak’ is the first word in the meaning.
From the second and third statement, we infer that ‘bly’ means ‘leaf’, so ‘crin’ will mean ‘maple’. Note that ‘crin’ is in the second half of the word.
We need to find those words from the artificial language that mean ‘maple syrup’.
Observe that ‘crin’ means ‘maple’.
Based on the pattern, since maple is the first word in ‘maple syrup’, ‘crin’ will be the second half of the coded word. That is true only for option 3.
Hence, option 3.

Each of the questions below starts with a few statements, followed by four conclusions numbered 1, 2, 3 and 4. You have to consider every given statement as true, even if it does not conform to the accepted facts. Read the conclusions carefully and then decide which of the conclusion(s) logically follow(s) from the given statements, disregarding commonly known facts.
In a certain code language the following lines written as –
‘lop eop aop fop’ means ‘Traders are above laws’
‘fop cop bop gop’ means ‘Developers were above profitable’
‘aop bop uop qop’ means ‘Developers stopped following traders’
‘cop jop eop uop’ means ‘Following maps were laws’
Developers are following laws’ would be correctly written as
- A.
‘bop cop uop eop’
- B.
‘lop bop eop uop’
- C.
‘oup cop lop aop’
- D.
None of the above
Answer: Option B
Explanation :
Consider the four statements
(i) “lop eop aop fop” means “Traders are above laws”
(ii) “fop cop bop gop” means “Developers were above profitable”
(iii) “aop bop uop qop” means “Developers stopped following traders”
(iv) “cop jop eop uop” means “Following maps were laws”
From (i) and (ii): “fop” ⇒ above
From (i) and (iii): “aop” ⇒ traders
So, in (i), “are” and “laws” will be represented by “lop” and “eop” in no particular order.
From (i) and (iv), “eop” ⇒ laws
So, “lop” ⇒ are
From (iii) and (iv), “uop” ⇒ following
From (ii) and (iii): “bop” ⇒ developers
So, “developers are following laws” would be written as “lop bop eop uop”
Hence, option 2.
Workspace:
‘qop gop cop eop’ would correctly mean:
- A.
Profitable laws were stopped
- B.
Developers stopped following laws
- C.
Traders were above profitable
- D.
None of the above
Answer: Option A
Explanation :
From the previous solution, “eop” ⇒ laws
So, the answer should have “laws” in the sentence.
Therefore, option 3 can be eliminated.
Also, looking at the previous solution, “developers”, “following” and “traders” have been identified.
So, “qop” ⇒ stopped. In (ii), “cop” and “gop” correspond to “were and “profitable” in some order”.
Therefore, “qop gop cop eop” would mean “profitable laws were stopped”.
Hence, option 1.

If the word ‘EXAMINATION’ is coded as 56149512965, then the word ‘GOVERNMENT’ is coded as:
- A.
7645954552
- B.
7654694562
- C.
7645965426
- D.
7654964526
Answer: Option A
Explanation :
EXAMINATION = 56149512965.
If we arrange them in alphabetical order, X = 24 and sum of digits of 24 is 6.
So, every number is substituted by its sum of digits.
So, GOVERNMENT = 7645954552.
Hence, option 1.

In a certain code language ‘HORSE’ is written as 71417184, then the word ‘MONKEY’ is coded as:
- A.
11141216425
- B.
12141310424
- C.
12151411325
- D.
12151210424
Answer: Option B
Explanation :
In this question every alphabet is substituted by one less than its numerical equivalent.
i. e. A = 0, B= 1, etc.
So, MONKEY = 12141310424.
Hence, option 2.
