• D. 60%

Answer 1

Answer:

C. 61.67%

There are 6 papers in total, each of 100 marks, so total maximum marks =
$6 \times 100 = 600$

Marks obtained:

Mathematics (3 papers):
60% of 100 = 60 marks each
$3 \times 60 = 180$

English (2 papers):
70% of 100 = 70 marks each
$2 \times 70 = 140$

Science (1 paper):
50% of 100 = 50 marks

Total marks obtained:

$180 + 140 + 50 = 370$

Overall percentage:

$\frac{370}{600} \times 100$

=61.67%
