(i) Total marks obtained by the student are 540. Hence, 540 marks represent 360º. The central angle for 105 marks has to be calculated.

Central angle for 105 marks =

Hindi is the subject having its central angle as 70º.

Therefore, the student scored 105 marks in Hindi.

Marks for 20º central angle =

There is a difference of 30 marks between the score obtained in Mathematics and Hindi.

Therefore, 30 more marks were obtained by the student in Mathematics than in Hindi.

(iii) Sum of central angles of Social Science and Mathematics
