Question : 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 $\mathrm{C} 4$ and $\mathrm{C} 6$? [Give your answer correct to 2 decimal places.]
Option 1: 11.11%
Option 2: 8.33%
Option 3: 9.09%
Option 4: 12.5%
Correct Answer: 8.33%
Solution :
From the given pie- chart,
C4 = 48°
C6 = 18°
We know, Percentage = $\frac{\text{Given Angle}}{360°}\times 100$
Percentage of C4 = $\frac{48°}{360°}\times100$
= 13.33%
Percentage of C6 = $\frac{18°}{360°}\times100$
= 5%
Difference = 13.33% – 5%
= 8.33%
Hence, the correct answer is 8.33%.
