Candidate A scores 25% and fails by 68 marks. Candidate B scores 50\% and gets 42 marks more than passing marks. Calculation: Let maximum marks be =x Marks scored by A=25% of x=0.25x Marks scored by B=50% of x=0.50x Passing marks = Marks scored by A+68=0.25x+68 Passing marks = Marks scored by B−42=0.50x−42 ⇒0.25x+68=0.50x−42 ⇒68+42=0.50x−0.25x ⇒110=0.25x ⇒x=110÷0.25 ⇒x=440
