Directions: Read the following information carefully and answer the questions given below.

Seven individuals — U, V, W, X, Y, Z, and K — are seated in a straight row facing north, but not necessarily in the same order.

W sits second from the right end of the line. Exactly three people sit between W and Y. X sits at an extreme end and is to the immediate left of Y. Only two people sit between Y and V. Z sits to the immediate left of V. U sits to the right of Y and to the left of Z. K occupies the seat to the immediate right of W.

How many persons sit between X and V?

The correct answer is Three.

Step-by-step explanation:

We are given seven individuals — U, V, W, X, Y, Z, and K — seated in a straight row facing north. Let us designate the 7 positions from left to right as 1, 2, 3, 4, 5, 6, and 7.

Step 1: Determine the positions of W and K
W sits second from the right end of the line, which corresponds to position 6.
K sits to the immediate right of W, placing K at position 7.
Arrangement: [ _ , _ , _ , _ , _ , W , K ]

Step 2: Determine the positions of Y and X
Exactly three people sit between W (position 6) and Y, which places Y at position 2.
X sits at an extreme end and to the immediate left of Y, placing X at position 1.
Arrangement: [ X , Y , _ , _ , _ , W , K ]

Step 3: Determine the positions of V and Z
Only two people sit between Y (position 2) and V, which places V at position 5.
Z sits to the immediate left of V, placing Z at position 4.
Arrangement: [ X , Y , _ , Z , V , W , K ]

Step 4: Determine the position of U
U sits to the right of Y and to the left of Z, occupying the remaining position 3.
Final seating arrangement from position 1 to 7: X, Y, U, Z, V, W, K

Conclusion:
X is at position 1 and V is at position 5.
The persons sitting between X and V are at positions 2, 3, and 4 (Y, U, and Z).
Therefore, exactly Three persons sit between X and V.
