Directions (87-91) : Study the following information carefully and answer the questions given below.

Twelve persons sit on twelve seats arranged in a row but only some persons are known and all of them are facing towards the north direction. Y is the only neighbour of S. Three persons sit between S and O who sits immediately left of K. More than three persons sit between K and H. K sits 2nd to the left of P who sits exactly between K and U. The number of persons sit between P and B is multiple of 2. The prime number of persons sits between H and B.

How many persons sit between K and U?

The correct option is Three.

Let us analyze the given information step-by-step to understand the arrangement:

1. Analyze the statement about K, P, and U:
The problem states: "K sits 2nd to the left of P who sits exactly between K and U."
Since P sits 2nd to the right of K, the position of P relative to K can be represented as:
K _ P
(where "_" represents an empty seat between K and P).

2. Determine the placement of U:
Since P sits exactly between K and U, the distance (number of seats/persons) from K to P must be equal to the distance from P to U.
The number of seats between K and P is 1 (P is 2nd to the right of K).
Therefore, the number of seats between P and U must also be 1, placing U 2nd to the right of P:
K _ P _ U

3. Count the total number of persons sitting between K and U:
In the arrangement K _ P _ U:
- There is 1 seat between K and P.
- There is the person P.
- There is 1 seat between P and U.
Thus, the total seats/persons between K and U are: 1 + 1 (P itself) + 1 = 3 persons.

Therefore, exactly 3 persons (or seats) sit between K and U.
