An exam is conducted for 600 marks.

Ramesh fails by 40 marks, so the passing marks are 200 + 40 = 240. Suresh scores 60% more than Ramesh: 200 × 1.60 = 320. Therefore, Suresh scores 320 − 240 = 80 marks more than the passing marks.

Step-by-step Derivation:
Step 1: Find passing marks.
Ramesh scores = 200 marks
Ramesh fails by = 40 marks
Passing marks = 200 + 40 = 240 marks

Step 2: Calculate Suresh's score.
Suresh scores 60% more than Ramesh
Suresh's score = 200 + (60% of 200)
Suresh's score = 200 + (0.60 × 200)
Suresh's score = 200 + 120 = 320 marks

Step 3: Find how many marks Suresh scored above passing marks.
Marks above passing = Suresh's score − Passing marks
Marks above passing = 320 − 240 = 80 marks

Answer: B) 80
