0 / 20
Question 1 of 20
Assertion (A): In opposite letter coding, the sum of the standard forward numerical positions of a paired letter combination is always 27. Reason (R): 'C' and 'X' form an opposite letter pair in the English alphabet.
Question 2 of 20
If a decoding program is fed the sequence '@@$$' and operates using the substitution key (A=$, R=@), what meaningful output will the program generate?
Question 3 of 20
If the word 'RAM' is coded as '18-1-13', what is the specific rule applied in this coding system?
Question 4 of 20
If in a specific language, the sequence of the alphabet is divided into two halves, what is the numerical positional value of the letter 'N' in standard forward coding?
Question 5 of 20
Which of the following is NOT a standard method of coding discussed in basic reasoning?
Question 6 of 20
Why is the strategy of memorizing specific coding rules (e.g., A always equals 1) generally considered completely useless by examination experts?
Question 7 of 20
If a coding system utilizes the rule of 'Opposite Letters' (e.g., A corresponds to Z, B corresponds to Y), how will the word 'CAB' be coded?
Question 8 of 20
Using the reverse alphabetical numerical coding system where Z=1, Y=2, and X=3, what will be the numerical code for the word 'BAY'?
Question 9 of 20
Consider the following statements regarding the rules of coding: I. It is highly useful to memorize all coding rules in advance to solve questions. II. Every coding question typically employs a distinct and unique rule. Which of the statements is correct?
Question 10 of 20
Which of the following scenarios perfectly illustrates the process of 'Decoding'?
Question 11 of 20
In the reverse alphabetical numerical coding system, what is the numerical value assigned to the letter 'X'?
Question 12 of 20
Assertion (A): In word substitution coding, factual real-world knowledge is necessary but not sufficient to answer the question. Reason (R): The final answer must always be derived by passing the real-world fact through the artificial substitution rule provided in the problem.
Question 13 of 20
What does the process of 'decoding' strictly involve?
Question 14 of 20
If a cryptographic rule pairs the letter 'D' exclusively with 'W', and the letter 'C' exclusively with 'X', what overarching logical framework is being utilized?
Question 15 of 20
If a code uses the logic of shifting to the '3rd letter ahead' (e.g., A becomes D), what will the letter 'P' become?
Question 16 of 20
What is the specialized term for the cognitive and systematic process of converting a seemingly arbitrary numerical sequence like '20-1-14-21' back into the meaningful name 'TANU'?
Question 17 of 20
Match List-I (Words) with List-II (Codes based on standard forward numerical values): List-I P. MAC Q. CAB R. BAD S. DAD List-II 1. 3-1-2 2. 4-1-4 3. 13-1-3 4. 2-1-4
Question 18 of 20
Match List-I (Alphabetical Letters) with List-II (Reverse Numerical Positions) correctly: List-I P. A Q. B R. C S. D List-II 1. 23 2. 24 3. 25 4. 26
Question 19 of 20
Which of the following pairs correctly represents the concept of 'Opposite Letters' in coding?
