=

540

105

×360

∘

=70

∘

Hindi's central angle is 70

∘

∴ Student scored 105 marks in Hindi

(ii)

Difference between central angles of Maths and Hindi

⇒90

o

−70

o

⇒20

o

Marks for 20

∘

central angles =

360

20

×540

∘

=30

∘

∴30 more marks were obtained by student in maths than in hindi

(iii)

Sum of central angles of social science and maths

=65

∘

+90

∘

=155

∘

Sum of central angles of Science and Hindi =80

∘

+70
