The given pie chart shows the amount of money spent by a school on various sports in the year 2015.

Study the pie chart carefully and answer the following question.
(i) If the amount spent on football was Rs. 9000, then how much more money was spent on hockey than on football ?
(ii) If the amount spent on football Rs. 9000, then what was the total amount spent on all sports ?

Answer

(i) Rs. 11000 , (ii) Rs. 72000

Explanation

(a) The amount spent on football = Rs. 9000
The central angle of the component hockey `=100^(@)`
Amount spent on hockey `=(100^(@)xx9000)/(45^(@))=Rs.20000`
`:.` The required difference Rs. 20000 - Rs. 9000 = Rs. 11000
(b) The amount spent on football =Rs. 9000
Central angle of the component football `=45^(@)`
Total amount spent on all sports `=(360^(@)xx9000)/(45^(@))=Rs.72000`
