In an examination, there were three papers of Mathematics, two papers of English and one paper of Science. All papers were of 100 marks. S got 60% in Mathematics, 70% in English and 50% in Science. What was his percentage of marks in all papers?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 61.67%.
Total papers and total marks
Math: 3 papers × 100 = 300
English: 2 papers × 100 = 200
Science: 1 paper × 100 = 100
Total = 300 + 200 + 100 = 600 marks
Marks obtained using %
Math: 60% of 300 = 180
English: 70% of 200 = 140
Science: 50% of 100 = 50
Total marks obtained = 180 + 140 + 50 = 370
Percentage = (370 / 600) × 100 = 61.67%
