Linear Seating Arrangement Questions and Answers

Answer: C

The statement that cannot be true is B and C are sitting together.

A and G have two benches between their benches, so they are on benches 1 and 4. G is behind both D and F, so G cannot be on bench 1: G is on 4 and A on 1. B and H also fill benches 1 and 4, one each. D is in front of F, and both are in front of G, so D is on bench 2 and F on bench 3. C and E take the remaining seats on benches 2 and 3, one on each.

So B is always on bench 1 or 4 and C always on bench 2 or 3: they can never share a bench. A and H can share bench 1, C can sit with F on bench 3, and E can sit with D on bench 2, so those three are possible.

Answer: C

The order that cannot occur is AFEB.

Taking one student from each bench, from front to back, the possible students are: bench 1, A or B or H; bench 2, D or C or E; bench 3, F or C or E; bench 4, G or B or H.

In AFEB, F is the student from bench 2, but F always sits on bench 3, so this order is impossible.

The others fit: ADFG takes A, D, F and G from benches 1 to 4; ADFB has B on bench 4; HCEG has H on bench 1, C on bench 2 and E on bench 3, which keeps C and E apart as required.

Answer: C

The pair that must sit together is A and H.

B and H are on benches 1 and 4, one on each. If B is on the last bench, H must be on bench 1, which is A's bench, so A and H sit together.

A and G are on benches 1 and 4 and are never together. C sits with D only if C is on bench 2, which is not forced, since E could take that seat. C and E are never on the same bench, by the given conditions.

Answer: A

Monika is in the middle (position 3) and Rosy is adjacent to her, so Rosy is at position 2 or 4. Rosy is not adjacent to Sivanandhini or Abi, so Rosy's other neighbour, at the end of the row, must be Anuradha.

So Anuradha sits next to Rosy, option A. Sivanandhini cannot be Anuradha's neighbour, and Monika is in the middle, not next to the end seat.

The arrangement is therefore Anuradha, Rosy, Monika in one corner of the row, with Sivanandhini and Abi in the other seats on the far side of Monika.

Answer: C

G is on the extreme left.

There are three people between G and B, so they are 5 places apart, and D is somewhere to the right of G. Try G in position 1 and B in position 5. C must be next to B with A on its other side, which forces B, C, A into positions 5, 6, 7. That leaves positions 2, 3, 4 for F, E and D, with E in the middle:

Every condition holds: D is right of G, C is between A and B, E is between F and D, and three people separate G and B. Trying B on the left of G fails: the B, C, A block and the F, E, D block cannot both fit. So G is at the extreme left, which rules out A, B and D.

Answer: C

The girl 2nd from the left is Reena.

Shikha is to the left of Reena, and Manju to the right of Reena with Rita between them. So the order from left to right is:

Shikha, Reena, Rita, Manju

Reena is second from the left. Shikha is first, Rita third and Manju last, so the other options are wrong.

A quick diagram of four places on a line, filled in clue by clue, avoids mixing up left and right in arrangement questions like this.

Answer: D

The answer is None of these.

R sits at the extreme left and K next to R, so the row starts R, K. T is not next to K, so T is in the 4th or 5th seat. S sits next to P but not next to T. If T were 4th, S would have to be 3rd or 5th, both next to T, which is not allowed. So T is 5th, S is 3rd and P is 4th:

R, K, S, P, T

S sits between K and P. No option names K and P, so 'P and T', 'R and P' and 'Only K' are all wrong, which leaves None of these.

Answer: B

Correct answer: X

S and Z occupy the two middle places, third and fourth, and A and P the two ends. R must sit to A’s left, which is only possible if A is at the far end - so P is first, R fifth and A sixth, leaving X second. The person to P’s right is therefore X.

Answer: C

Correct answer: Taud is in between Paul and Jack

Paul takes one of the two middle houses, and Harry stands immediately left of Larry with at least one house further to their left. Mike lives between Paul and Larry, which seats Harry, Larry, Mike and Paul in houses 2 to 5. Because Harry is immediately left of Larry, Harry would lie between Taud and Larry whenever Taud is further left - the question rules that out, so Taud is to Larry’s right. At least one boy lives right of Robert, so Robert is not in house 8, and Jack must stay clear of Siman. The row reads:

1 Jack · 2 Harry · 3 Larry · 4 Mike · 5 Paul · 6 Siman · 7 Robert · 8 Taud

Checking the statements: Robert is in house 7, not the left end; Robert does stand between Siman and Taud; and Siman, Robert and Taud - three boys - live to Paul’s right. But Taud is at the far right of the row and Jack at the far left, with Paul between them, so Taud is not between Paul and Jack. That is the statement which is not correct.

Answer: B

Correct answer: Between B and C

E is at the left end and C second from the right, that is fourth of five. A must sit beside C and to the right of both B and E, which puts A third and B second, with D fifth beside C. The bench reads E, B, A, C, D, so A sits between B and C.
