Practice Questions
Concept Explanation
Examination problems link marks scored, maximum marks, pass marks, and percentage scores. Percentage = (marks obtained/maximum marks) × 100.
Passing Marks
If pass marks are 40% of maximum M, pass marks = 0.4M.
Failed By / Passed By
If a student scores 30% and fails by 30 marks while pass is 40%, then 10% of max = 30, so max = 300.
Comparing Candidates
Convert each score to a percentage of respective maximum before comparing.

Q1 EasyIn an examination, pass marks are 40% of the maximum marks. A student scores 30% and fails by 30 marks. What is the maximum marks of the examination?ExplanationGap between pass and scored marks = 10% of maximum = 30. Maximum marks = 300.
-
Q2 EasyA student needs 35% marks to pass an examination of 800 marks. If she scores 252 marks, by how many marks does she fail or pass?ExplanationPass marks = 35% of 800 = 280. She scored 252, so she fails by 280 − 252 = 28 marks.
-
Q3 EasyIn an examination, 65% of 400 marks is required for distinction. How many marks are needed for distinction?ExplanationDistinction marks = 65% of 400 = 260.
-
Q4 MediumTwo students appeared at an examination. One of them secured 9 marks more than the other and his marks was 56% of the sum of their marks. The marks obtained by them are:ExplanationLet marks be (x + 9) and x. Then x + 9 = (56/100)(2x + 9) → 25(x + 9) = 14(2x + 9) → 3x = 99 → x = 33. Marks are 42 and 33.
-
Q5 MediumIn an examination, a candidate must secure 40% marks to pass. A candidate, who gets 220 marks fails by 20 marks. What are the maximum marks for the examination?ExplanationPass marks = 220 + 20 = 240. Since pass marks = 40% of maximum, maximum = 240 × (100/40) = 600.
-
Q6 MediumIn an examination it is required to get 36% of maximum marks to pass. A student getting 113 marks and declared failed by 85 marks. The maximum marks are:ExplanationPass marks = 113 + 85 = 198. Maximum marks = 198 × (100/36) = 550.
-
Q7 MediumA student scores 40% of marks and fails by 40 marks in the examination; another student scores 60% and scores 20 more than passing marks. Find the maximum marks for the examination.ExplanationDifference in percentages = 20%. Difference in marks = 40 + 20 = 60. So 20% of maximum = 60 → maximum = 300.
-
Q8 MediumIn an examination, there are three subjects of 100 marks each. A student scores 60% in the first subject and 80% in the second subject. He scored 70% in aggregate. His percentage of marks in the third subject is:ExplanationAggregate marks = 70% of 300 = 210. Marks in third subject = 210 − 60 − 80 = 70, which is 70% of 100.
-
Q9 MediumRavi scored 540 marks out of 600 in one test and Mohan scored 425 marks out of 500 in another test. Who obtained the higher percentage of marks?ExplanationRavi = (540/600) × 100 = 90%. Mohan = (425/500) × 100 = 85%. Ravi scored higher.
-
Q10 MediumIn a test of 750 marks, a student obtains 82% marks. How many marks did the student score?ExplanationMarks obtained = 82% of 750 = 615.
-
Q11 MediumPriya scored 84 marks out of 120 and Kiran scored 105 marks out of 150 in the same aptitude round. Who has the higher percentage score?ExplanationPriya = (84/120) × 100 = 70%. Kiran = (105/150) × 100 = 70%. Both have equal percentage.
-
Q12 HardIn an examination, there are three papers and a candidate has got 35% of the total to pass. In one paper, he gets 62 out of 150 and in the second 35 out of 150. How much must he get, out of 180, in the third paper to just qualify for a pass?ExplanationTotal maximum = 480. Pass marks = 35% of 480 = 168. Marks in first two papers = 97. Required in third paper = 168 − 97 = 71.
-
