Question

The adjoining pic chart gives the expenditure on various items during a month for a family. (The numbers written around the pie chart tell us the angles made by each sector at the centre.)

Answer the following – 

(i) On which item is the expenditure minimum? 

(ii) On which item is the expenditure maximum? 

(iii) If the monthly income of the family is ₹ 9000, what is the expenditure on rent? 

(iv) If the expenditure on food is ₹ 3000, what is the expenditure on education of children?

Answer 1

i) Education 

ii) Food 

iii) Total income is represented by 360° = Rs. 9,000 

food represented by 120 = \(\frac {120}{360}\)× 9000 = Rs. 3000 

iv) The expenditure on food is represented by 120 = Rs. 3000 

Then expenditure on education is represented by  \(\frac {60}{120}\)× 3000 = Rs. 1500
