A candidate scores 25% and fails by 30 marks, while another candidate scores 50% and passed by 20 marks. Find the maximum marks for the examination.
Answer & explanation
Correct answer: option 1
Let total marks/maximum marks = M
Pass marks
⇒ (M × 25%) + 30 = (M × 50%) - 20
⇒ (50% - 25%) M = 30 + 20
⇒ 25% of M = 50
⇒ M = 200
