Correct Answer: A
Explanation:
Draw a table of possible combinations.
For Statements 2 and 3, we find that Ali must be in second slot and that Haroon must be in the third slot because Haroon cannot be in the end apartment. There are , then, two possible apartment position combinations:
|
Apartment 1 |
Apartment 2 |
Apartment 3 |
Apartment 4 |
| Combination 1 |
Mustafa |
Ali |
Haroon |
Afzal |
| Combination 2 |
Afzal |
Ali |
Haroon |
Mustafa |
Now, since Mustafa owns the white car and Afzal owns the black car, we find the possible apartment position and car color combinations to be the following:
|
Apartment 1 |
Apartment 2 |
Apartment 3 |
Apartment 4 |
| Possibility 1 |
Mustafa: white |
Ali: Orange |
Haroon: Maroon |
Afzal: Black |
| Possibility 2 |
Mustafa: White |
Ali: Maroon |
Haroon: Orange |
Afzal: Black |
| Possibility 3 |
Mustafa: Black |
Ali: Orange |
Haroon: Maroon |
Afzal: White |
| Possibility 4 |
Mustafa: Black |
Ali: Orange |
Haroon: Maroon |
Afzal: White |
Now we can proceed to answer the questions with reference to the table above
The table shows that, if A owns the orange car, the B must own the maroon car. So Choice A is correct
