Answer 1

Answer:

(a) Student score 105 marks in Hindi

(b) 30 more marks

(c) Yes, sum of marks obtained in Social science and Mathematics are more than the marks scored in Science and Hindi .

Step-by-step explanation:

We are provided with the pie chart in which marks of students in Mathematics, Social science, Science, Hindi and English are represented.

Also, the total marks scored by students were 540.

(a) Marks scored by student in Hindi = $\frac{70}{360} *540$ { $\because$ sum of all degrees of pie

                                                                                  chart is 360° }

                                                             = $\frac{70}{2}*3$ = 105

Therefore, In Hindi student score 105 marks.

(b) Marks scored by student in Mathematics = $\frac{90}{360} *540$ = 135 marks

    Marks scored by student in Hindi = $\frac{70}{360} *540$ = 105 marks

So, student score 30 more marks in mathematics than in Hindi as               135 - 105 = 30 marks.

(c)  Marks scored by student in Social science = $\frac{65}{360} *540$ = 97.5 marks

     Marks scored by student in Science = $\frac{80}{360} *540$ = 120 marks

Total marks scored in Mathematics and Social science = 135 + 97.5

                                                                                            = 232.5 marks

Total marks scored in Science and Hindi = 120 + 105

                                                                    = 225 marks

Yes, sum of marks obtained in Social science and Mathematics are more than the marks scored in Science and Hindi as 232.5 > 225 .
