Question

An exam is made of two papers that score differently.

Answer 1

Answer:

Maryam TOTAL percentage score for the exam is:

                             71%

Step-by-step explanation:

Paper--1

 Total marks=120 marks.

The percent score scored by Maryam is:  65%

This means that the score scored by Maryam is: 0.65×120=78

Paper--2

   Total marks=80

The percent score scored by Maryam is:  80%

This means that the score scored by Maryam is: 0.80×80=64

Hence, Total marks of both the paper are: 120+80=200 marks

Marks scored by Maryam in both the subjects is: 78+64=142 marks

Hence, Total percentage score for the exam is:

        $=\dfrac{142}{200}\times 100\\\\\\=\dfrac{142}{2}\\\\\\=71\%$

           Hence, her total percent score is:

                         71%

   

Answer 2

71 %

Calculate score for each paper, total them and convert to a percentage.

Paper 1 : mark = 0.65 × 120 =78

Paper 2 :mark = 0.8 ×80 = 64

Total mark = (78 + 64)/200 =142/200

Percentage score = 142/200 × 100 % = 71 %
