GAT general analytical reasoning questions portion evaluates how efficiently students can reason to solve logical arrangement based on given three to five sets of conditions in such a short span of time. If a student can accurately extract the information out of the analytical reason question statement and conditions then it becomes very easier to solve. Students can also make diagrams and sketches to organize information in better way to solve the puzzle type analytical reasoning questions.

Explanation of Each Question
Question 1:
Which of the following letters could be placed after “O” in L-O to form a computer lab’s code word exactly 3 letters long?
Correct Answer: A (K)
Explanation:
- Rule 5 states that O cannot be the last letter unless L is in the word, and since L already appears in “L-O”, O can be followed by K.
- K can follow O here, and it satisfies all the rules.
Why are the other options incorrect?
- O: Cannot repeat O as the last letter (Rule 5).
- M: M cannot be the second-to-last letter (Rule 3).
- N: While possible, K is the correct answer based on the context.
- L: L is already in the word, so repeating it here does not make the word incorrect, but K is the better option.
Question 2:
If the only kinds of letters that are available are K, L, and M, then the total number of different computer lab’s code words, each exactly two letters long, that it is possible to make is?
Correct Answer: A (1)
Explanation:
- K cannot be the first letter, and L must appear more than once. Therefore, the only valid two-letter word is L-L.
Why are the other options incorrect?
- There is only one valid combination (L-L), so options like 3, 6, 9, and 12 are incorrect.
Question 3:
Which of the following is an acceptable computer lab’s code?
Correct Answer: E (M-L-L-O)
Explanation:
- M-L-L-O follows all the rules:
- M is not the last or second-to-last letter.
- L appears more than once.
- O is the last letter, but L appears, which is allowed.
Why are the other options incorrect?
- K-L-L-M: K cannot be the first letter (Rule 1).
- L-O-M-L: M cannot be the second-to-last letter (Rule 3).
- O-N-K-M: K cannot appear without N before it.
- N-M-K-O: M cannot be the second-to-last letter (Rule 3).
Question 4:
What are the total number of different computer lab’s code words exactly three identical letters long that it is possible to make?
Correct Answer: B (2)
Explanation:
- The only two possibilities are L-L-L and O-O-O, as these satisfy the rules.
- L-L-L is valid because L can appear multiple times.
- O-O-O is valid because O is allowed when it’s not the last letter.
Why are the other options incorrect?
- There are only two valid three-letter identical codes, not 1, 3, 4, or 5.
Question 5:
The computer lab’s code word M-M-L-L-O-K-N can be turned into another computer lab’s code word by carrying out any one of the following changes EXCEPT:
Correct Answer: E (Replacing the N with an O)
Explanation:
- Replacing N with O violates Rule 4 because N is required if K is in the word.
Why the other options are correct?
- Replacing L with N is fine because N can replace L.
- Replacing the first M with O is valid.
- Moving the second L next to K or moving O next to N still satisfies all the rules.
Question 6:
Which one of the following is not a computer lab’s code word but could be turned into one by changing the order of the letters within the word?
Correct Answer: D (N-K-L-M-L)
Explanation:
- By rearranging this to L-L-K-N-M, it satisfies all the rules.
- L appears twice.
- K is not the first letter.
- M is not in the last or second-to-last position.
- N is there because K appears in the word.
Why are the other options incorrect?
- K-L-M-N-O: K is the first letter, violating Rule 1.
- L-L-L-K-N: No change is needed, it’s already a valid code.
- M-K-N-O-N: K violates Rule 4 (it needs N before it).
- O-M-M-L-L: It’s already a valid code word.
Question 7:
Which of the following could be turned into a computer lab’s code word by replacing the “X” with the letter used in the computer lab’s code?
Correct Answer: E (X-O-K-L-L)
Explanation:
- Replacing X with N makes this a valid code word: N-O-K-L-L.
- L appears twice.
- O is not the last letter without L.
- K appears with N before it.
Why are the other options incorrect?
- M-K-X-N-O: No valid letter can replace X without violating a rule.
- M-X-K-M-N: No valid letter can replace X without violating a rule.
- X-M-M-K-O: M cannot be in the second-to-last position.
- X-M-O-L-K: K needs N to appear in the word if it is present.
