Q.2Hard
Six people A, B, C, D, E, F sit around a square table (one on each side, two at each corner). D is opposite to B. C is to the left of D. E is at a corner. Which position is A most likely to occupy?
Answer: C
Square table with 6 people (4 sides + 2 corners). D opposite B. C left of D. E at corner. A's position determined by elimination. A is opposite to E.
Q.3Hard
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.
Q.4Hard
If West is called North, North is called East, East is called South, South is called West, then which direction is to the left when facing South?
Answer: C
South is called West in new terminology. When facing 'called West' (actual South), left side is actual East, which is called South. So answer is actual West.
Q.5Hard
Eight people sit around a square table with two on each side. P sits opposite to Q. R sits to the immediate left of P. S sits opposite to R. How many people sit between S and Q (clockwise)?
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.6Hard
Pointing at a man in a photograph, a woman says, 'His mother's only child's mother is my mother.' What is the relationship?
Answer: B
His mother's only child = the man himself. The man's mother = the woman's mother. This means they're siblings, or the woman is pointing at her husband (if we interpret differently). The answer is husband.
Q.7Hard
Five people A, B, C, D, E have different heights. C is taller than D but shorter than A. B is taller than E. A is taller than B. Who is the second tallest?
Answer: D
Order: A > C > D and A > B > E. Without knowing relationship between C and B exactly, second tallest cannot be definitively determined.
Q.8Hard
In a logic puzzle, 6 boxes are arranged left to right. Red box is 3 positions from left. Green is 2 right of Yellow. Blue is immediate left of Red. If there are only 4 colors, where is Yellow?
Answer: A
Red at 3, Blue at 2. Green 2 right of Yellow: if Yellow at 1, Green at 3. But Red at 3. If Yellow at 4, Green at 6. This works: Blue(2), Red(3), Yellow(4), Green(6). Yellow at position 4... Rechecking: Yellow could be at 1 if Green at 3, but Red there. So Yellow at 4.
Q.9Hard
In a seating arrangement, 6 people sit around a hexagonal table. M is 2 seats away from N (clockwise). K is opposite to M. Who sits between K and N (clockwise)?
Answer: B
We know M, N (2 seats away clockwise), and K (opposite M). But without knowing other people's positions or exact starting point, the person between K and N cannot be uniquely determined.
Q.10Hard
All professors are knowledgeable. Some knowledgeable people are not teachers. Which of the following must be true?
Answer: A
Professors ⊂ Knowledgeable. Some knowledgeable people are not teachers. Therefore, some of those non-teachers in the knowledgeable group could be professors. A must be true.
Q.11Hard
Six people A, B, C, D, E, F sit around a circular table. A sits opposite D. B sits between A and F. C is not adjacent to A. E sits to the right of A. How many arrangements are possible?
Answer: B
With A opposite D, B between A and F, E to right of A, and C not adjacent to A, there are 2 valid arrangements satisfying all constraints.
Q.12Hard
In a puzzle box, 5 items (Watch, Pen, Ring, Chain, Locket) are placed in 5 boxes. Watch is not in box 1 or 5. Ring is in box 3. Pen is immediately to the left of Chain. Locket is not adjacent to Ring. How many valid arrangements exist?
Answer: B
With Ring at box 3, Pen-Chain in consecutive positions (boxes 1-2 or 4-5), Watch not at 1 or 5, and Locket not at 2 or 4, only 2 arrangements satisfy all constraints.
Q.13Hard
Seven students P, Q, R, S, T, U, V are ranked. T ranks higher than R. U ranks higher than Q but lower than S. P ranks lowest. How many students rank lower than Q?
Answer: D
While we know P is lowest and relative positions of others, Q's exact position relative to all students cannot be uniquely determined from given constraints.
Q.14Hard
In a linear arrangement of 8 seats, P, Q, R, S, T, U, V, W sit in a row. P sits at one end. Q sits 3rd from the left. T sits between R and S. U sits to the immediate right of Q. Who sits at the right end?
Answer: C
Insufficient information provided about positions of all people relative to given constraints.
Q.15Hard
Seven containers are arranged in order. Container 3 has more items than Container 2. Container 5 has fewer items than Container 6. Container 7 has the most items. If Container 4 has more than Container 3, which container has more items: Container 2 or Container 5?
Answer: D
The given conditions don't establish a direct comparison between Container 2 and Container 5.
Q.16Hard
In a coding system, vowels are replaced by the next consonant and consonants by the next vowel. How is LOGIC coded?
6 boxes are arranged in a row. Box 2 is heavier than Box 1. Box 4 is lighter than Box 3. Box 5 is heavier than Box 6. If Box 3 is heavier than all others, which box is the lightest?
Answer: C
While we know Box 4 < Box 3 and Box 6 < Box 5, we cannot definitively compare Box 1, 2, 4, and 6 to determine the lightest.
Q.18Hard
In a complex arrangement, 9 boxes are placed in 3 rows and 3 columns. Box at position (1,2) contains Red balls. Position (2,3) contains Green balls. Position (3,1) contains Blue balls. If you need to place Yellow balls such that no two colors share a row or column, where should Yellow go?
Answer: A
Red at (1,2) blocks row 1 and column 2. Green at (2,3) blocks row 2 and column 3. Blue at (3,1) blocks row 3 and column 1. Yellow must avoid: rows 1,2,3 and columns 1,2,3 - impossible for standard placement, but (2,1) conflicts with Blue's column 1. Rechecking: (1,3) at row 1 conflicts with Red's row. (2,1) at column 1 conflicts with Blue's column. Best option avoiding maximum conflicts: (2,1).
Q.19Hard
Eight boxes labeled 1-8 are arranged in a line. Box 3 is between boxes 2 and 4. Box 5 is immediately right of box 4. Box 8 is immediately left of box 1. What is the arrangement?
Answer: D
The constraints 'Box 3 between 2&4' and 'Box 5 right of Box 4' and 'Box 8 left of Box 1' create conflicting arrangements in a linear sequence. Box 8 cannot be immediately left of Box 1 in a line where boxes are numbered sequentially.
Q.20Hard
A woman's son's mother's father's only daughter is the woman herself. What is the relation?
Answer: A
Woman → Son's mother = Woman. Woman's father = Boy's grandfather. Grandfather's only daughter = Woman. This is logically consistent - she is indeed her son's mother and her father's only daughter.
