How much minimum marks will be required to pass an examination? (M.A.T., 2005) I. Student A secured 32% marks in that examination and he failed by 1 mark. Student B secured 36% marks in the same examination and his marks were 1 more than the minimum pass marks. II. Student A secured 30% of full marks in the ex- amination and he failed by 2 marks. If he had secured 5 more marks his percentage of marks would have been 40%.

Nothing is invented here, so this question has no answer on record.
Explanation
Let the maximum marks be x. PERCENTAGE From I, we have: 32% of x + 1 = 36% of x – 1 4 ⇒ x = 2 ⇒ x = 50. 100 \ Pass marks = 32% of 50 + 1 = 17. From II, we have: 30% of x + 2 = 40% x – 3 10 ⇒ x = 5 ⇒ x = 50. 100 \ Pass marks = 30% of 50 + 2 = 17. So, I alone as well as II alone gives the answer. \ Correct answer is (c).
