Difficulty: EasySeating Arrangement

Five colored cars (Red, Blue, Green, Black, and White) are parked in a single straight row facing North.

- The Green car is parked at the extreme left end.
- The Black car is parked exactly in the middle of the row.
- The Blue car is parked immediately to the left of the Black car.
- The White car is parked immediately to the right of the Red car.

Based on the given information, which car is parked at the extreme right end of the row?

  1. White carAnswer
  2. B
    Red car
  3. C
    Green car
  4. D
    Black car

Answer

The White car is parked at the extreme right end.
By mapping out the five slots from left to right, we find the Green car in the first slot and the Black car in the third slot. The Blue car sits immediately to the left of Black, taking the second slot. This leaves only the fourth and fifth slots open. Because the White car is parked immediately to the right of the Red car, the Red car must be in the fourth slot and the White car in the fifth slot, which is the extreme right end.

Step-by-Step Solution

1
Determine the total number of positions and label them.
There are 5 parking slots. Label them 1 to 5 from left to right.
Creating a numbered framework makes it easier to place each car precisely.
2
Place cars based on absolute position clues.
Green car is in slot 1. Black car is in slot 3.
The statements explicitly state Green is at the extreme left and Black is exactly in the middle.
3
Place the Blue car based on relative position to the Black car.
Blue car is in slot 2.
It is parked immediately to the left of the Black car (slot 3).
4
Determine the positions of the remaining cars (Red and White).
Red car is in slot 4 and White car is in slot 5.
Only slots 4 and 5 are empty. Since the White car is immediately to the right of the Red car, Red must take slot 4 and White must take slot 5.
