ii) how many more marks were obtained by the students in mathematics then Hindi
iii)examine whether the sum of marks obtained in social science and mathematics is more than science in Hindi​

Answer 1

Answer:

i) Hindi

ii) 90-70=20°

iii) No

Step-by-step explanation:

Total marks: 540

i) Hindi

$\frac{105}{540}%=19.44$

19.44% of 360 = 69.984 ≅ 70°

ii) 90-70=20°

20/360 * 540 = 30

iii) No

1° = 540/360 = 1.5

S Science: 65 x 1.5 = 97.5

Mathematics: 90 * 1.5 = 135

Science: 80 * 1.5 = 120

Hindi = 70 * 1.5 = 105

S Science + Maths = 232.50

Science + Hindi = 325

Answer 2

Answer:

i) 70° - Hindi

ii) 30

iii) yes

Step-by-step explanation:

i) 540 = 360°

For 150 = 360/ 540 = 2/3

                           = 2/3 × 105

                           = 70°

the student score 105 marks in Hindi

ii) Mark obtained in Maths = 90/360 = 1/4

                                           = 1/4 x 105

                                           = 135

Marks obtained in Maths more than hindi

                                           = 135 - 105

                                           = 30

iii) Central angle of social science and maths

                                           = 65° + 90°

                                           = 155

   Central angle of science and hindi

                                          = 80° + 70°

                                          = 150

Yes, Social science and maths is more than Science and hindi.

hope it is helpful
