Question
Answer the questions based on the information given
below: Six student D, E, F, G, H and I scored different marks in a exam. G scored more than three student. F scored more than G. H and D scored more than I. At least one student scored more than D. Neither F nor H scored the highest. Who scored the 3rd lowest marks?Solution
As G scored more than three student. F scored more than G. H and D scored more than I. At least one student scored more than D. Neither F nor H scored the highest, so E scored the highest. E > F > G > H/D > D/H > I
