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

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: C

Correct answer: Fourth to the left

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

W sits sixth and Z second, so Z is fourth to W’s left.

Answer: D

Correct answer: V

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

Counting two places to T’s right gives Z and then V.

Answer: B

Correct answer: XV

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

In UW, ZT, YV and WX the two named sit side by side. X and V have Y between them, so that pair does not belong.

Answer: E

Correct answer: TU

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

The row begins with T and ends with U, so those two hold the extreme ends.

Answer: B

Correct answer: D

All seven face north, so right means east. B is at the extreme right, G two places to his left and E between them. Three people separate F from G, which puts F second from the left; and D three places to C’s left then fills the rest in one way only. From left to right the row reads D, F, A, C, G, E, B.

The first place in the row is D’s.
