Solution
The correct option is D 120 The given pie chart shows the marks obtained in the form of degrees.
Given,
Total marks obtained = 400
So, 360° = 400 marks
Now, we can calculate the marks obtained in each subject as follows.
Marks secured in mathematics = (Centralangleofmathematics/360°)360o×Totalscoresecured
= (108°)360°×400 = 120 marks
