Question 1

Four persons — W, X, Y, and Z — sit in two parallel rows of two persons each. Row 1 persons face North and Row 2 persons face South (so each person faces exactly one person in the other row). W and X are in Row 1. Y and Z are in Row 2. X sits to the right of W (from X's perspective, facing North). Z faces W. Which of the following pairs sit in the same row and are immediate neighbours?

Accepted Answer

Row 1 (faces North): Left and Right seats → W and X. X sits to the right of W from X's perspective facing North: facing North, right = East = increasing position. So W is at Left of Row 1 and X is at Right of Row 1. Row 2 (faces South): Left and Right seats → Y and Z. Z faces W: W is at Left of Row 1, so Z is at Left of Row 2 (they face each other). Y is at Right of Row 2. Same-row immediate neighbours: Row 1 → W and X are neighbours. Row 2 → Y and Z are neighbours. W and X are in Row 1 and are immediate neighbours.

Question 2

Five people—X, Y, Z, W, V—sit in two parallel rows. Row 1 has three seats; Row 2 has two seats. Row 1 faces Row 2. X, Y, Z sit in Row 1 from left to right. W, V sit in Row 2 from left to right. Y sits in the middle of Row 1. W sits directly opposite Y. V sits to the right of W. Which person in Row 1 does NOT have anyone sitting directly opposite them?

Accepted Answer

This tests understanding of parallel rows with unequal seat counts and identifying unmatched positions.

Question 3

Seven people sit in two parallel rows: Row X (5 seats, facing South) and Row Y (5 seats, facing North). Some seats may be empty.

Clues:
1. Vikram sits at Position 2 in Row X.
2. Priya sits directly opposite Vikram in Row Y.
3. Aditya sits two positions to the right of Vikram in Row X (at Position 4).
4. Neha sits directly opposite Aditya in Row Y.
5. Rohan sits at Position 1 in Row X.
6. Simran sits immediately to the right of Rohan in Row X.
7. Kavya sits directly opposite Rohan in Row Y.

How many empty seats are there in total across both rows?

Accepted Answer

This puzzle tests counting and the ability to recognize that not all seats need to be filled. Students must place all seven people and count the remaining empty seats.

Question 4

Four people—M, N, O, P—sit in two parallel rows of two seats each. Row 1 faces Row 2. M sits in Row 1, left seat. N sits in Row 1, right seat. O sits in Row 2, left seat. P sits in Row 2, right seat. If we consider the person sitting to the left of N in Row 1, who sits directly opposite that person?

Accepted Answer

This tests the ability to identify a person based on relative position, then find their opposite.

Question 5

Five people—V, W, X, Y, Z—sit in two parallel rows of 3 seats each. Row I faces Row II. V sits in Row I, Position 1. W sits in Row I, Position 2. X sits in Row I, Position 3. Y sits directly opposite W in Row II, Position 2. Z sits directly opposite V in Row II, Position 1. Who sits in Row II, Position 3?

Accepted Answer

Row I: V (Position 1), W (Position 2), X (Position 3). Row II: Z (Position 1, opposite V), Y (Position 2, opposite W), ? (Position 3). We have 5 people: V, W, X, Y, Z. All are assigned. Row II, Position 3 is not assigned to any of the 5 people. The position is empty, or the puzzle is under-constrained. However, if the question implies someone must sit there, we must re-examine. Since only 5 people are named and all are placed (V, W, X in Row I; Z, Y in Row II), Row II, Position 3 has no one from the given list. The answer is 'No one' or 'Cannot be determined.' If forced to choose from the given options, the most logical answer is that the position is unoccupied.

Question 6

Four people—M, N, O, P—sit in two parallel rows of 2 seats each. Row X faces Row Y. M sits in Row X, Position 1. N sits directly opposite M in Row Y, Position 1. O sits in Row X, Position 2. P sits directly opposite O in Row Y, Position 2. If we consider the perspective of someone sitting in Row Y facing Row X, who sits to the right of N?

Accepted Answer

Row Y (facing Row X): N (Position 1), P (Position 2). From N's perspective in Row Y facing Row X, 'right' means toward higher position numbers. Position 2 in Row Y is occupied by P. Therefore, P sits to the right of N.

Question 7

Seven people—A, B, C, D, E, F, G—sit in two parallel rows of 4 seats each (Row 1 and Row 2). Row 1 faces Row 2. A sits in Row 1, Position 2. B sits directly opposite A in Row 2, Position 2. C sits immediately to the right of A in Row 1, Position 3. D sits immediately to the left of A in Row 1, Position 1. E sits directly opposite C in Row 2, Position 3. F sits directly opposite D in Row 2, Position 1. G sits in Row 2, Position 4. How many people sit between D and C in Row 1?

Accepted Answer

Row 1: D (Position 1) — A (Position 2) — C (Position 3) — ? (Position 4). Between D and C, there is exactly one person: A. Therefore, 1 person sits between D and C.

Question 8

Six people—P, Q, R, S, T, U—sit in two parallel rows of 3 seats each. Row A faces Row B. P sits in Row A, Position 1. Q sits directly opposite P in Row B, Position 1. R sits in Row A, Position 3. S sits directly opposite R in Row B, Position 3. T sits in Row A, Position 2. U sits in Row B, Position 2. If we consider 'left' from the perspective of someone sitting in Row A facing Row B, who sits to the left of T?

Accepted Answer

Row A (facing Row B): P (Position 1), T (Position 2), R (Position 3). From T's perspective in Row A facing Row B, 'left' means toward Position 1. Position 1 in Row A is occupied by P. Therefore, P sits to the left of T.

Question 9

Six people—P, Q, R, S, T, U—sit in two parallel rows (Row A and Row B) with 6 seats each, facing each other. Row A faces East; Row B faces West.
