The given pie chart shows the expenditure (in degrees) incurred in making a book.
Question 150
In Others there are only two types of expenditures viz. Marketing and Distribution in ratio 3 : 2 respectively. What will be the central angle (in degrees) made by the sector of expenditure on Marketing?
Solution
Expenditure (in %) in others = 15%
Expenditure on Marketing (in %) = $$\frac{3}{(3+2)}\times15=9\%$$
=> Central angle (in degrees) made by the sector of expenditure on Marketing = $$\frac{9}{100}\times360^\circ$$
