Which of the following is true?

The information can be reproduced as follows:
Karan > Rahul > Dana > Sudha = Parul > Abhishek > Bharat
Dana is the correct answer.

According to question , we can say that
P, Q, R, S, T, V and W are sitting in a straight line facing north. Each one of them lives on a different floor in the same building which is numbered from one to seven. Q sits fourth to the left of the person living on the 6th floor. W lives on the 3rd floor. The person living on the 1st floor sits third to right of S. S is not an immediate neighbor of W. Only one person lives between T and the person who lives on the 2nd floor.
Except S, all others live on a floor with odd number.
Therefore , There are three floors between the floors on which V and P live .

According to question , we can say that
P, Q, R, S, T, V and W are sitting in a straight line facing north. Each one of them lives on a different floor in the same building which is numbered from one to seven. Q sits fourth to the left of the person living on the 6th floor. W lives on the 3rd floor. The person living on the 1st floor sits third to right of S. S is not an immediate neighbor of W. Only one person lives between T and the person who lives on the 2nd floor.
Clearly , 2nd floor is required answer .

As per the given above question , we have
P, Q, R, S, T, V and W are sitting in a straight line facing north. Each one of them lives on a different floor in the same building which is numbered from one to seven. Q sits fourth to the left of the person living on the 6th floor. W lives on the 3rd floor. The person living on the 1st floor sits third to right of S. S is not an immediate neighbor of W. Only one person lives between T and the person who lives on the 2nd floor. P and R are immediate neighbours of each other. P does not live on the 6th floor.
From figure it is clear that S amongst the following lives on the 4th floor .

According to question , we can say that
In row 1, P, Q, R, S and T are seated and all of them are facing south. In row 2, A, B, C, D and E are seated and all of them are facing north.
From figure we can see that E amongst the following faces S .

_ > _ > _ > _ C > A, E ...........(i)
B > D > _ > _ > _ > _ ...........(ii)
Since E did not score the least, we get B > D > F (81) > C > E (62) > A
(e) is the correct answer;

_ > _ > _ > _ C > A, E ...........(i)
B > D > _ > _ > _ > _ ...........(ii)
Since E did not score the least, we get B > D > F (81) > C > E (62) > A
(a) is the correct answer; C is most likely to score 70 marks as he is between F, who scored 81 marks and E, who scored 62 marks.

Given that Six products - Ariel, Vivel, Rin, Nirma, Gillette Gel and Pepsodent
From 1st condition: Rin and Ariel are next to each other.
From 2nd condition at least two products are between Ariel &Nirma
From 3rd condition Pepsodent is kept between Gillette Gel and Rin, and at least 2 products between Pepsodent and Vivel.
From 4th condition: Vivel and Rin can not be next to each other.
From 5th condition Vivel is not kept at 1st window.
Final arrangement would be Nirma Gillette Pepsodent Rin Ariel Vivel
Except Rin , the product displayed left of Ariel but right lof Gillette Gel is Pepsodent.

Given that Six products - Ariel, Vivel, Rin, Nirma, Gillette Gel and Pepsodent
From 1st condition: Rin and Ariel are next to each other.
From 2nd condition at least two products are between Ariel &Nirma
From 3rd condition Pepsodent is kept between Gillette Gel and Rin, and at least 2 products between Pepsodent and Vivel.
From 4th condition: Vivel and Rin can not be next to each other.
From 5th condition Vivel is not kept at 1st window.
Final arrangement would be Nirma Gillette Pepsodent Rin Ariel Vivel
if we interchange the position of Rin and Ariel, the item displayed in window 5 will be Rin.

Given that Six products - Ariel, Vivel, Rin, Nirma, Gillette Gel and Pepsodent
From 1st condition: Rin and Ariel are next to each other.
From 2nd condition at least two products are between Ariel &Nirma
From 3rd condition Pepsodent is kept between Gillette Gel and Rin, and at least 2 products between Pepsodent and Vivel.
From 4th condition: Vivel and Rin can not be next to each other.
From 5th condition Vivel is not kept at 1st window.
Final arrangement would be Nirma Gillette Pepsodent Rin Ariel Vivel
From case II of the above Rin is left of Ariel.
Hence, the answer is (3).
