Linear Seating Arrangement Questions and Answers

Answer: B

Correct answer: Four

Only two people sit to S’s right, so S is sixth in the line, and T three places to her left is third. One person separates T from X and X sits immediately right of W, which puts X fifth and W fourth; Z, one person from W, takes the second place. U three places from X, and Y barred from either end, then leave V at the first place and U at the eighth. From left to right the line reads V, Z, T, W, X, S, Y, U.

S faces north and T, being opposite her, faces south. T’s neighbours Z and W face the same way as each other, V faces as W does, and Y and U face opposite to Z. Taking Z’s side as north makes V, Z, W and S the four facing north, with T, X, Y and U facing south.

Answer: D

Correct answer: T, Y

S faces north with only two people to his right, so S sits sixth. T is third to S’s left, in seat 3. One person sits between T and X, X is immediately right of W, one person sits between W and Z, and U is third to X’s left; together these fix the row. The facing rules then follow - T is opposite S, T’s two neighbours match each other, V matches W, and Y and U are both opposite Z:

1 V (N) · 2 Z (N) · 3 T (S) · 4 W (N) · 5 X (S) · 6 S (N) · 7 Y (S) · 8 U (S)

So V, Z, W and S face north while T, X, Y and U face south. Each of the other four pairs puts one person from each group together - W and X, Z and Y, T and S, V and U all face opposite ways. T and Y are the exception: both face south, so that pair does not belong.

Answer: B

Correct answer: Third to the right

Only two people sit to S’s right, so S is sixth in the line, and T three places to her left is third. One person separates T from X and X sits immediately right of W, which puts X fifth and W fourth; Z, one person from W, takes the second place. U three places from X, and Y barred from either end, then leave V at the first place and U at the eighth. From left to right the line reads V, Z, T, W, X, S, Y, U.

Z sits second and X fifth. Z faces north, so her right is east, and X is three places that way.

Answer: A

Correct answer: T

Only two people sit to S’s right, so S is sixth in the line, and T three places to her left is third. One person separates T from X and X sits immediately right of W, which puts X fifth and W fourth; Z, one person from W, takes the second place. U three places from X, and Y barred from either end, then leave V at the first place and U at the eighth. From left to right the line reads V, Z, T, W, X, S, Y, U.

Z sits second and W fourth, so the one place between them, the third, belongs to T.

Answer: B

Correct answer: V

Only two people sit to S’s right, so S is sixth in the line, and T three places to her left is third. One person separates T from X and X sits immediately right of W, which puts X fifth and W fourth; Z, one person from W, takes the second place. U three places from X, and Y barred from either end, then leave V at the first place and U at the eighth. From left to right the line reads V, Z, T, W, X, S, Y, U.

T faces south, so his right is to the west. Two places that way from the third seat is the first, which belongs to V.

Answer: B

Correct answer: AB

They face east, so right means south. D is third from the south end with C just south of him; B is at the north end with E beside him, and G sits between E and F. From north to south the wall holds B, E, G, F, D, C, A.

The two ends of the wall are held by B at the north and A at the south.

Answer: B

Correct answer: AB

They face east, so right means south and left means north. D is third from the south end and C just to his right, that is just south of him. B is at an end with E beside him, which can only be the north end, and G sits between E and F. Reading from north to south the wall holds B, E, G, F, D, C, A.

The two ends of the wall are held by B at the north and A at the south.

Answer: D

Correct answer: All informations are necessary

They face east, so right means south and left means north. D is third from the south end and C just to his right, that is just south of him. B is at an end with E beside him, which can only be the north end, and G sits between E and F. Reading from north to south the wall holds B, E, G, F, D, C, A.

Every clue does work: without any one of them the places of the others could not all be fixed, and A’s seat is only settled once the rest are. So all the information is necessary.

Answer: C

Correct answer: C F

They face east, so right means south and left means north. D is third from the south end and C just to his right, that is just south of him. B is at an end with E beside him, which can only be the north end, and G sits between E and F. Reading from north to south the wall holds B, E, G, F, D, C, A.

D sits fifth from the north, with F on one side and C on the other.

Answer: A

Correct answer: G

They face east, so right means south and left means north. D is third from the south end and C just to his right, that is just south of him. B is at an end with E beside him, which can only be the north end, and G sits between E and F. Reading from north to south the wall holds B, E, G, F, D, C, A.

The third seat from the north belongs to G, so that is the person C would have to change places with.
