Six persons J, K, L, X, Y and Z secured different marks in the examination. No two persons secured the same marks.
Neither X nor Y secured more marks than Z. Two persons secured more marks than Z.
Neither X nor Y secured the lowest marks.
| | Case 1 | Case 2 |
| Sr. no | Persons (marks secured in descending order) | Persons (marks secured in descending order) |
| 1 | | |
| 2 | | |
| 3 | Z | Z |
| 4 | X | Y |
| 5 | Y | X |
| 6 | | |
More than two persons secured different marks between L and X.
Thus, case 1 is invalid.
| | Case 2 |
| Sr. no | Persons (marks secured in descending order) |
| 1 | L |
| 2 | |
| 3 | Z |
| 4 | Y |
| 5 | X |
| 6 | |
J does not secure the second-highest marks.
Therefore, the final arrangement is:
| Sr. no | Persons (marks secured in descending order) |
| 1 | L |
| 2 | K |
| 3 | Z |
| 4 | Y |
| 5 | X |
| 6 | J |
L secured the highest marks.
