Question

Pie chart shows marks obtained by student in various subjects Hindi, English,Mathematics, Social Science and Science.

If total marks obtained by these students are 900 then answer the following questions

(i) In which subject did student have 250 marks?

(ii) That student obtained how many marks more in mathematics as compared to Hindi?

(iii) Check whether total marks obtained in Social Science and Mathematics is more than total of marks obtained in English and Hindi?

Answer 1

(i) Part of whole = 250/900

∴ Part of 360° = 250/900 x 360°

= 100°

Hence, student has obtained 250 marks in Maths.

(ii) Marks obtained in Maths = 250

Marks obtained in Hindi

= 72/360 x 900

= 180

∴ Difference of marks between Maths and Hindi = 250 – 180 = 70

(iii) Marks obtained in Social Science

= 60/360 x 900

= 150

Marks obtained in Maths = 250

∴The sum of marks obtained in Social Science and Maths : 150 + 250 = 400

Marks obtained in English

= 48/360 x 900 = 120

Marks obtained in Hindi = 180

∴Sum of marks obtained in English and Hindi = 120 + 180 = 300

Hence, the sum of marks obtained in Social Science and Maths is more than the sum of marks obtained in English and Hindi.
