In an examination, the passing mark is 49 of the total marks. If Rajnish scores 45% out of a total of 810, by how much does he exceed the passing mark?
4.5
Total marks in the examination = 810
Passing mark = 49× 810 = 360
Rajnish's score = 45100×810 = 364.5
∴ Rajnish has scored 364.5 - 360 = 4.5 marks more than the passing mark.
