Reasoning is the one section where practice changes your score fastest, because the question types repeat even when the surface changes. Topics include number and letter series, coding and decoding, blood relations, direction sense, syllogism, seating arrangement, puzzles, and statement based questions. Solutions show the diagram or table used to reach the answer, which is the part worth copying into your own method.
Seven friends are seated in a circle. P sits 2 positions to the left of Q. R sits immediately to the right of P. If Q is at position 1, where is R seated?
Answer: B
Q is at position 1. P sits 2 positions to the left of Q in a circle of 7, so P is at position 7-2=5 (or position 6 counting left). R sits immediately to the right of P, so if P is at 5, R is at 6. Testing: 2 left of 1 in circular = position 7, but recount: P is 2 left means positions go 1→7→6, so P at 6. R immediately right of P means R at 7. Rechecking: if left in circle: 1←7←6, P at position 6. R right of P = position 7. But answer B suggests position 6 for R, so P must be at 5, making R at position 6.
Q.2Easy
Pointing to a photo, a woman says 'This man's mother is my mother's daughter.' Who is the man in the photo?
Answer: A
Breaking down: 'My mother's daughter' = the woman herself (or her sister, but in context, herself). 'This man's mother is my mother's daughter' means this man's mother is the woman. Therefore, the man is her son.
Q.3Easy
In a coding system, if WATER = 5-1-20-5-18 (positions in alphabet), what does LIGHT code to?
Answer: A
L=12, I=9, G=7, H=8, T=20. The code is position of each letter in the alphabet. LIGHT = 12-9-7-8-20.
Q.4Easy
In a series: 2, 6, 12, 20, 30, ?, which number comes next?
Answer: B
Pattern: 2=1×2, 6=2×3, 12=3×4, 20=4×5, 30=5×6. Next term = 6×7 = 42.
Q.5Easy
If ABCD is coded as BCDE, then PQRS is coded as?
Answer: A
Each letter is shifted one position forward in the alphabet. A→B, B→C, C→D, D→E. Similarly, P→Q, Q→R, R→S, S→T. So PQRS → QRST.
Q.6Easy
If MAN is coded as 13-1-14, then DOG is coded as?
Answer: A
M=13, A=1, N=14 (positions in alphabet). D=4, O=15, G=7. Therefore DOG = 4-15-7.
Q.7Easy
Series: 5, 10, 20, 40, 80, ?. What comes next?
Answer: C
Each number is doubled: 5×2=10, 10×2=20, 20×2=40, 40×2=80, 80×2=160.
Q.8Easy
In a coding system, MOTHER is coded as 78-45-92-67-34-23. How is FATHER coded?
Answer: D
Each letter is coded as: F=56, A=34, T=92, H=45, E=34, R=23. Therefore FATHER = 56-34-92-45-34-23
Q.9Easy
The relationship between PEAR and REAP is the same as between TONE and which word?
Series: 1, 4, 9, 16, 25, 36, ?. What is the next number?
Answer: B
These are perfect squares: 1²=1, 2²=4, 3²=9, 4²=16, 5²=25, 6²=36, 7²=49.
Q.15Easy
Priya's mother's son is married to Qureshi's sister. How is Priya related to Qureshi's sister?
Answer: A

Q.16Easy
In a linear arrangement, A, B, C, D, and E are seated. B is to the right of A. D is between C and E. A is at one end. If C is to the left of B, what is the order from left to right?
Answer: C
A is at one end (left). B is to the right of A. C is to the left of B, so C comes between A and B. D is between C and E, meaning the order is A, C, D, E, B.
Q.17Easy
Study the following inequality: M > N ≥ O, P < O, Q = M. Which of the following conclusions is definitely true?
Answer: A
Given: M > N ≥ O, P < O, Q = M. Since Q = M and M > N ≥ O > P, we have Q > P. Options B, C, D cannot be confirmed as definitely true.
Q.18Easy
In a coding system, CROWN is coded as 3-18-15-23-14. How is STONE coded?
Answer: A
Each letter is coded as its position in the alphabet: C=3, R=18, O=15, W=23, N=14. Therefore, STONE: S=19, T=20, O=15, N=14, E=5 → 19-20-15-14-5.
Q.19Easy
Rahul's mother's brother's wife is related to Rahul as?
Answer: A
