Show answer & explanation
Correct answer: C
Explanation
Given:
Ravi = 40% marks, failed by 30 marks
Sohan = 50% marks, 20 marks more than the passing marks
Let the maximum marks = x
Ravi's marks = 40% of x = 0.4x
Passing marks = 0.4x + 30
Sohan's marks = 50% of x = 0.5x
Sohan scores 20 marks more
0.5x = (0.4x + 30) + 20
0.5x = 0.4x + 50
0.1x = 50
x = 500
