A candidate who gets 30% of the marks fails by 50 marks. But another candidate who gets 45% marks gets 25 marks more than necessary for passing. Find the number of marks for passing:
Explanation:
Let aggregate score be M and pass marks be x.
Then, by conditions of the problem, 0.3M = x – 50,
and, 0.45M = x + 25
Solving these simultaneous equations we get x = 200 marks
Hence, option (b).
