Q1. In a certain code language, LAW is written as MBX. How will COURT be written in the same code?

A. DPVSU
B. DQVSU
C. DPWTV
D. BNTQS

Answer: A. DPVSU

Solution:
Each letter is replaced by the letter immediately following it in the English alphabet.

• L → M

• A → B

• W → X

Therefore:

• C → D

• O → P

• U → V

• R → S

• T → U

Hence, COURT → DPVSU.

Q2. In a certain code language:

• COURT CASE is written as 17 31

• LEGAL NOTICE is written as 25 42

• COURT NOTICE is written as 17 42

What is the code for LEGAL CASE?

A. 25 31
B. 31 25
C. 17 25
D. 42 25

Answer: A. 25 31

Solution:
From the statements:

• COURT = 17

• CASE = 31

• LEGAL = 25

• NOTICE = 42

Therefore:

LEGAL CASE = 25 31.

Q3. If in a certain code PEN = 35, LAW = 36, and BOOK = 43, the code represents the sum of the alphabetical positions of the letters. What is the code for JUDGE?

A. 45
B. 46
C. 47
D. 48

Answer: B. 47

Solution:

JUDGE:

• J = 10

• U = 21

• D = 4

• G = 7

• E = 5

Total:

10 + 21 + 4 + 7 + 5 = 47

Therefore, the correct answer is actually C. 47.

Q4. In a certain code language:

COURT IS OPEN → ka ti mo
LAW IS IMPORTANT → ra ti su
COURT LAW → ka ra

Which code represents IMPORTANT?

A. ka
B. ra
C. su
D. ti

Answer: C. su

Solution:
Compare the statements:

COURT IS OPEN → ka ti mo
LAW IS IMPORTANT → ra ti su
COURT LAW → ka ra

From the third statement:

• COURT = ka

• LAW = ra

In the second statement:

LAW = ra
IS = ti

Therefore the remaining code:

IMPORTANT = su.

Q5. If CAT = 24 and DOG = 26, then what is the code for LAW, using the sum of the alphabetical positions of its letters?

A. 36
B. 37
C. 38
D. 39

Answer: C. 36

Solution:

LAW:

• L = 12

• A = 1

• W = 23

Therefore:

12 + 1 + 23 = 36

So the correct answer is actually A. 36.

• Learn forward positions (A=1, Z=26) and reverse positions of all 26 letters using shortcuts like EJOTY (multiples of 5) to save calculation time.

• Practice on basics: letter shifting, number/symbol coding, word substitution, and message deciphering through elimination.

• Treat coding and decoding as a backup topic skill by spending only 10% of your Logical Reasoning time on it, as CLAT heavily prioritizes reading-based Critical Reasoning.

• Solve past year questions before looking at multiple-choice answers to build strong, independent pattern-recognition skills.

• Practice 5 to 10 coding questions weekly to keep your mental math, tracking reflexes, and analytical agility sharp for the exam.
