Question
Six students L, M, N, O, P, and Q scored different
marks in an exam. O scored more than Q and L. Three students scored more than P, who scored just more than M. O does not score the highest number of marks. If L scored more marks than P, then who scored the lowest number of marks?Solution
N O L P M Q
