In these questions, we represent all possible alternatives in a tabular representation. With the help of the hints, we put a tick or a cross in each cell of the table if that particular cell is definitely true or if it is definitely false. After this, we again go over the table and eliminate any choice which has been rendered impossible by the hint. We represent the information in the question as follows:

In the above representation, we have used the following abbreviations:
In subjects: P - Physics
C - Chemistry
M - Maths
B - Biology
CS - Computer Science
E - English
We will start with the hints that give us direct information first.
Using hint 7, neither A nor E had scored 82, nor were their scores scored in Biology or Physics.

Using hint 8, C had scored 86, but not in Physics.

Using hint 10, D's score was in Maths.

Using hint 5, 82 was not scored in Maths.

C scored 86 from point 8, also, 88 was scored in Biology and 84 was scored in Computer Science, so C did not appear in Biology or Computer Science.

Using hint 4, the score in English was not 86.

Hence, C gave the Chemistry exam.

Since B and F will score in Physics and Biology, A and E will score in Computer Science and English.

Using hint 9, A did not score 84 or 89.

Using hint 3, 84 was scored in Computer Science and the one who scored it was the topper.

Hence, A scored in English.

Using hint 6, B was not second, the person who was second scored 82.

Using hint 2, 88 was scored in Biology.

Filling the remaining places,

Using hint 1, the numerical sum of the ranks and the marks of C and D are the same.
C's rank was 6.

There are 6 students A, B, C, D, E, F who appeared in 6 different subj...

Explanation:

Given Information:
- C scored 86
- 88 was scored in Biology
- 84 was scored in Computer Science and the topper scored it
- English was not 86
- 82 was not scored in Maths
- B was not second, the person who was second scored 82
- A and E did not score 82, Biology, or Physics
- A did not score 84 or 89
- D's score was in Maths

Analysis:
- From the given information, we know that C scored 86 and D's score was in Maths.
- So, the numerical sum of the ranks and marks of C and D are the same.
- Therefore, D must have scored 88 in Maths (since C scored 86).
- Since the person who scored 84 was the topper in Computer Science, B cannot be the topper in Computer Science.
- Since B was not second and the person who was second scored 82, B cannot be the second rank.
- Since A and E did not score 82, Biology, or Physics, and A did not score 84 or 89, A must have scored 88 in Physics.
- Since 88 was scored in Biology, F must have scored 88 in Biology.
- Since English was not 86, E must have scored 86 in English.
- Therefore, C scored 82 in Maths and D scored 86 in Physics.

Conclusion:
- Based on the above analysis, we can conclude that the rank 6 belongs to C. Hence, the answer is option C.
