Question

The adjoining pie chart gives the expenditure on various items during a month for a family. (The number 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 Rs. $9000$, what is the expenditure on rent?
iv) if the expenditure on food is Rs. $3000$, what is the expenditure on education of children?

Answer 1

Savings	$=\frac{{90}^{\circ }}{{360}^{\circ }}\times 9000=Rs.2250$
Education	$=\frac{{60}^{\circ }}{{360}^{\circ }}\times 9000=Rs.1500$
Rent	$=\frac{{90}^{\circ }}{{360}^{\circ }}\times 9000=Rs.2250$
Food	$=\frac{{1200}^{\circ }}{{360}^{\circ }}\times 9000=Rs.3000$

On education expenditure is minimum.

On food expenditure is maximum.
