Detailed Solution
Download Solution PDFSix boxes - M, N, O, P, Q and R, are kept one above the other but not necessarily in the same order.
1. There is no box above box P.
2. Box R is third from the bottom.

|
|
|
|
R |
|
|
|
|
3. There is only one box between box N and box R.

Case I |
Case II |
|

|

|
|
R |
R |
|
|
|
|
|
N |
4. Box Q is immediately below box N.
The above condition cannot be satisfied in Case II, so it is eliminated.
|
Case I |
|
P |
|
N |
|
Q |
|
R |
|
|
|
|
3. There are only two boxes between box Q and box M.
|
Case I |
|
P |
|
N |
|
Q |
|
R |
|
|
|
M |
Only one box O is left and it will occupy the vacant position.
So, the final arrangement is shown below:
|
Case I |
|
P |
|
N |
|
Q |
|
R |
|
O |
|
M |
Clearly, box Q is third from the top.
Hence, ‘Q’ is the correct answer.
