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 people A, B, C, D, E, F, G sit around a circular table facing the center. D sits second to the left of A. B sits third to the right of A. E sits between C and F. Who sits to the immediate right of G?
Answer: A
Using circular arrangement logic: A's position is fixed. D is 2nd to left (clockwise from A's perspective). B is 3rd to right. E between C and F helps determine the remaining positions. C sits to immediate right of G.

In a certain code, MATHEMATICS is written as 13-1-20-8-5-13-1-20-9-3-19. How is SCIENCE written?
Answer: A
The code uses position of letters in the alphabet. S=19, C=3, I=9, E=5, N=14, C=3, E=5. Therefore SCIENCE = 19-3-9-5-14-3-5.
Q.23Easy
Pointing to a photograph, a man says, 'She is the daughter of my mother's only son's wife.' Who is the woman in the photograph?

Q.24Medium
If facing North-East, turning 135 degrees clockwise and then 45 degrees counter-clockwise, which direction are you facing?
Answer: B
Starting North-East (45°). Turn 135° clockwise: 45° + 135° = 180° (South). Turn 45° counter-clockwise: 180° - 45° = 135° (South-East), which simplifies to East direction.
Q.25Medium
2, 5, 12, 27, 58, __, 246
Answer: A
Pattern: Each term = 2 × previous term + 1. 2→5(2×2+1), 5→12(2×5+2), 12→27(2×12+3), 27→58(2×27+4), 58→121(2×58+5), 121→246(2×121+4).
Q.26Medium
All triangles are polygons. Some polygons are rectangles. Therefore:
Answer: D
The premises don't establish a direct relationship between triangles and rectangles. While all triangles are polygons and some polygons are rectangles, we cannot conclude about the intersection of triangles and rectangles.
Q.27Easy
FLOWER : REWOLF :: GARDEN : ?
Answer: A
The analogy reverses the spelling. FLOWER reversed = REWOLF. GARDEN reversed = NEDRAG.
Q.28Medium
Five boxes A, B, C, D, E are kept on a shelf. B is to the right of A. C is to the left of D. E is between C and D. D is to the right of B. What is the order?
Answer: A
B right of A: A-B. C left of D: C-D. E between C and D: C-E-D. D right of B: combining gives A-B-C-E-D.
Q.29Easy
In a code, if PENCIL is written as 16-5-14-3-9-12, how is PAPER written?
Answer: A
Each letter is coded by its position in the alphabet. P=16, A=1, P=16, E=5, R=18. So PAPER = 16-1-16-5-18.
Q.30Medium
No cats are dogs. All dogs are animals. Which statement is valid?

Answer: A
In a square table arrangement with 2 people per side: P and R on one side (R left of P), Q opposite P, S opposite R. Going clockwise from S to Q, there are 2 people between them.
Q.36Medium
In a certain language, HELLO is coded as GDKKN. How is WORLD coded?
Answer: A
Each letter shifts back by 1 position: H→G, E→D, L→K, L→K, O→N. Applying same logic: W→V, O→N, R→Q, L→K, D→C = VNQKC.
Q.37Medium
All flowers are plants. Some plants are green. Therefore:
Answer: D
While flowers are plants, the second statement only says some plants are green. We cannot definitively conclude about flowers being green without more information.
Q.38Easy

Q.39Hard
Pointing at a man in a photograph, a woman says, 'His mother's only child's mother is my mother.' What is the relationship?
