The following pie chart shows the sectors representing the shares of the number of electric buses manufactured in each of 7 different colours in a given year in terms of the central angles (in degrees) with respect to the total number of buses manufactured during that year of all the 7 colours taken together.
What is the difference in the percentage shares of buses of C4 and C6? [Give your answer correct to 2 decimal places.]
difference in the degree shares of buses of C4 and C6 = $$48^{\circ\ }-18^{\circ\ }$$ = $$30^{\circ\ }$$
We know that $$360^{\circ\ }=\ 100\%$$.
So $$30^{\circ\ }=\ \frac{100}{12}\%$$
difference in the percentage shares of buses of C4 and C6 = $$\frac{100}{12}\%$$
= 8.33%
