Linear Seating Arrangement Questions and Answers

Answer: A

Correct answer: None

All seven face north, so right means east. W sits five places to T’s right and not at an end, so T is first and W sixth; Y is exactly in the middle and U three places to Y’s right. Z must be three places from X and not beside Y, which fixes the rest. From left to right the row reads T, Z, V, Y, X, W, U.

Seating them alphabetically from right to left would put Z first, Y second, X third and so on to T at the far right. Comparing that with the row above, not one of the seven keeps the place they already hold, so the answer is none.

Answer: B

A is at middle position, so arrangement will be like this at this stage

Now it is told that that there is no person to the right of E, it means E is at the extreme right of the line ⇒ E is at the position 7. It is also told that D is at extreme corner of row and adjacent to B. Since one end is already occupied by E so D will be at position 1 and B will be at position 2. So our arrangement will be like:

Again, it is told that there is only one person between E and F and it is also told that B and C are opposite side of A. Since B is on the left side of A, so C will be on the right side of A. Since there is only one person between E and F so position 6 will be occupied by C and F at 5. Now only one position is remaining so that will be lled by G.

Hence, position of G is between A and B.

Answer: B

It is given that the seven trees are facing north, thus

LEFT -- -- -- -- -- -- -- RIGHT

From (ii), the Ashoka tree is planted at the extreme right, end of the row. (LEFT) -- -- -- -- -- -- Ashoka (RIGHT)

The statement “the papaya tree is planted fourth to the right of the नीब tr ू ee” can be represented in two ways:

(LEFT) -  Lemon  -- -- -- Papaya  Ashoka (RIGHT)

OR

(LEFT) Lemon  -- -- -- Papaya  -- Ashoka (RIGHT)

The statement “the mango and guava trees are immediate neighbours of the नीब tr ू ee” indicates the rst case will hold true.

Mango  Lemon Guava -- -- Papaya  Ashoka

OR

Guava  Lemon   Mango -- -- Papaya  Ashoka

The statement “the banana tree is planted immediately next to the mango tree” indicates the second case will hold true.

Guava  Lemon   Mango Banana -- Papaya  Ashoka

The nal arrangement is as follows:

Guava  Lemon   Mango Banana Apple Papaya  Ashoka

From above, the apple tree is fourth to the right with respect to the guava tree.

Answer: E

It is given that the seven trees are facing north, thus

LEFT -- -- -- -- -- -- -- RIGHT

From (ii), the ashoka tree is planted at the extreme right, end of the row. (LEFT) -- -- -- -- -- -- Ashoka (RIGHT)

The statement “the papaya tree is planted fourth to the right of the lemon tree” can be represented in two ways:

(LEFT) -  Lemon  -- -- -- Papaya  Ashoka (RIGHT)

OR

(LEFT) Lemon  -- -- -- Papaya  -- Ashoka (RIGHT)

The statement “the mango and guava trees are immediate neighbours of the lemon tree” indicates the rst case will hold true.

Mango  Lemon  Guava -- -- Papaya  Ashoka

OR

Guava  Lemon  Mango -- -- Papaya  Ashoka

The statement “the banana tree is planted immediately next to the mango tree” indicates the second case will hold true.

Guava  Lemon  Mango Banana -- Papaya  Ashoka

The nal arrangement is as follows:

Guava  Lemon  Mango Banana Apple Papaya  Ashoka

Lemon Mango

Banana Apple

Mango Banana

Guava Lemon

are immediate neighbors.

The rst tree is to the immediate left of the second tree in every option.

Apple tree is second to the left of Ashoka tree.

Answer: D

Now it is told that, there is no person to the left of A and P is sitting second to the right of A.

⇒ 1st position is occupied by the boy that is A and 3rd position is occupied by P that is girl.

From information (2), D is sitting at 8th position and he is a boy.

From information (1), C is sitting at 6th position and 5th and 7th position can be occupied by either R or S.

Therefore, our arrangement will look like

Now one of the positions from 2 and 4 will be occupied by boy and second one will be occupied by the girl.

From Information (3), B is a boy and he is sitting between two girls ie. at 4th position.

From information (4), Q is a girl and should be sitting at 2nd position.

Now our arrangement will look like

From above explanation, it is clear that number of boys between Q and R can be either 1 or 2.

Answer: C

Now it is told that, there is no person to the left of A and P is sitting second to the right of A.

⇒ 1 position is occupied by the boy that is A and 3 position is occupied by P that is girl.

From information (2), D is sitting at 8 position and he is a boy.

From information (1), C is sitting at 6 position and 5 and 7 position can be occupied by either R or S.

Therefore, our arrangement will look like

Now one of the positions from 2 and 4 will be occupied by boy and second one will be occupied by the girl.

From Information (3), B is a boy and he is sitting between two girls ie. at 4 position.

From information (4), Q is a girl and should be sitting at 2 position.

Now our arrangement will look like

From this it is clear that the complete list of boys who are sitting in the row are A, B, C and D.

Answer: D

Row 1        A B C D

Row 2        P Q R S

C sits second to the right of the person from Bank of Maharashtra.

R is an immediate neighbor of the person who faces the person from Bank of Maharashtra.

Only one person sits between R and the person from PNB.

CASE I

CASE II

CASE III

Immediate neighbor of the person from PNB faces the person from Canara Bank.

CASE I

CASE II

Canara Bank can’t be on second place as Bank of Maharashtra is present there.

CASE III is not possible as the only position which can be available to Canara Bank is occupied by Bank of Maharashtra.

P is not from PNB. P does not face the person from Bank of Maharashtra.

CASE I

CASE II

Q faces the person from Dena Bank. The person who faces 'S' sits immediately to the left of 'A'.

CASE I

CASE II

B does not sit on any of the extreme ends of the line.

Case I is invalid as B cannot be on either extreme ends.

Hence our case is

CASE II

The person from Bank of Maharashtra does not face the person from Syndicate Bank.

The person from UCO bank faces the person from Oriental Bank of Commerce. R is not from Oriental Bank of Commerce. Hence, the nal arrangement is as follows.

The persons from Oriental Bank of Commerce, Canara Bank and Syndicate Bank and R are on the extreme ends of the rows. Hence Q is the odd one who is not part of the group.

Answer: D

Row 1        A B C D

Row 2        P Q R S

C sits second to the right of the person from Bank of Maharashtra.

R is an immediate neighbor of the person who faces the person from Bank of Maharashtra.

Only one person sits between R and the person from PNB.

CASE I

CASE II

CASE IIIImmediate neighbor of the person from PNB faces the person from Canara Bank.

CASE I

CASE II

Canara Bank can’t be on second place as Bank of Maharashtra is present there.

CASE III is not possible as the only position which can be available to Canara Bank is occupied by Bank of Maharashtra.

P is not from PNB. P does not face the person from Bank of Maharashtra.

CASE I

CASE II

Q faces the person from Dena Bank. The person who faces S sits immediately to the left of A.

CASE I

CASE II

B does not sit on any of the extreme ends of the line.

Case I is invalid as B cannot be on either extreme ends.

Hence our case is

CASE II

The person from Bank of Maharashtra does not face the person from Syndicate Bank.

The person from UCO bank faces the person from Oriental Bank of Commerce. R is not from Oriental Bank of Commerce. Hence the nal arrangement is as follows.

The relation is such that the person from the given bank is immediate left to the person facing the given person.

Hence, R is sitting opposite to D. The person from the Indian Bank is sitting immediately to the left of R.

Answer: C

Step 1: P, Q, R, S, T, U and V are sitting on a bench and all of them are facing east. S is sitting fth from the North end and R is to the immediate right of S, but not next to U.

Step 2: Q is at the extreme end and has T as his neighbor and V is between T and U.

Here, P is automatically filled. Clearly, P and Q are sitting at extreme end of the bench.

Answer: A

Step 1: P, Q, R, S, T, U and V are sitting on a bench and all of them are facing east. S is sitting fth from the North end and R is to the immediate right of S, but not next to U.

Step 2: Q is at the extreme end and has T as his neighbor and V is between T and U.

Here, P is automatically filled.

Hence, S is sitting between U and R.
