The following pie-chart shows the monthly expenditure of Shikha on various items. If she spends Rs 16000 per month, answer the following questions:
(i) How much does she spend on rent?
(ii) How much does she spend on education?
(iii) What is the ratio of expenses on food and rent?
(i) Money spent on rent $=\frac{\text { Central angle of the corresponding sector } \times \text { Total Money spent }}{360^{\circ}}$
$=\frac{81^{\circ} \times 16000}{360^{\circ}}=\operatorname{Rs} 3,600$
(ii) Money spent on education $=\frac{\text { Central angle of the corresponding sector } \times \text { Total Money spent }}{360^{\circ}}$
$=\frac{36^{\circ} \times 16000}{360^{\circ}}=$ Rs 1,600
(iii) Money spent on food $=\frac{\text { Central angle of the corresponding sector } \times \text { Total Money spent }}{360^{\circ}}$
$=\frac{135^{\circ} \times 16000}{360^{\circ}}=6,000$
Ratio of expenses on food and rent $=\frac{6000}{3600}=\frac{5}{3}$
