Read the following information carefully and answer the questions give...
1. A is at the extreme right end of the row
2. There are at least two people and at most five people sitting between A and Z.
3.Y is to the immediate left of Z who is not an immediate neighbour of X.
4. Y is sitting between X and Z. X is on even numbered seat when counted from right end. Not more than two people are sitting between X and Y. Y is to the immediate left of Z who is not an immediate neighbour of X.
5. There are three people between X and W. The number of people sitting on the left of W is three less than that of his right.
6. There are only two people between U and V. V is an immediate neighbour of W. There are less than five people to the left of U and there are neither 6 nor 8 people between Y and U. Number of people sitting between A and Z and number of people sitting between Y and X is not same.
These conditions are possible only in case 2
Hence, seven persons sit to the right of X.

Solution
From the given information, we can determine the following:
- A is at the extreme right end, so A is the 1st person from the right end.
- X is on an even-numbered seat, so X is the 2nd person from the right end.
- There are three people between X and W, and V is an immediate neighbour of W, so W is the 6th person from the right end and V is the 7th person.
- Y is between X and Z, and Y is to the immediate left of Z, so Z is the 4th person from the right end.
- There are only two people between U and V, so U is the 5th person from the right end.
- Y is not an immediate neighbour of X, so Y is the 3rd person from the right end.
- There are at least two people and at most five people between A and Z, which means Z is the 4th, 5th, 6th, or 7th person from the right end.
- There are neither 6 nor 8 people between Y and U, so there are 4 people between Y and U.
- Not more than two people are between X and Y, so there is 1 person between X and Y.
Therefore, there are 7 people to the right of X. Hence, the correct answer is option c) Seven.
