Show answer & explanation
Correct answer: B
Let the maximum marks be x.
Ajay's marks = 30% of x = 0.3x. Since Ajay failed by 10 marks, passing marks = 0.3x + 10.
Vijay's marks = 40% of x = 0.4x. Vijay scored 15 marks more than the passing marks, so passing marks = 0.4x - 15.
Equate the two expressions for passing marks: 0.3x + 10 = 0.4x - 15.
Solve: 0.4x - 0.3x = 10 + 15 => 0.1x = 25 => x = 250.
Now passing marks = 0.3*250 + 10 = 75 + 10 = 85.
Answer: Passing marks = 85.
