Question

In an examination, there are three papers, each of 100 marks. A candidate obtained
64 marks in the first paper and 76 marks in the second paper. If he has to get an
overall score of 80%, how many marks does he need to score in the third paper?​

Answer 1

Answer:

Total marks =100+100+100=300

Let x marks obtained by the candidate in third paper

Marks obtained by the candidate in second paper =75

Mark obtained in first paper =53

Total marks obtained by the candidate =53+75+x−128+x

ACQ,

300

128+x

⇒x=210−128

⇒x=82

Therefore, the candidate must obtain 82 marks in the third paper.
