Question : The pie chart given below shows the number of cars sold by 8 different companies. The total number of cars sold by all these 8 companies is 5,000. The number of cars sold by a particular company is shown as a percentage of the total number of cars sold by all these 8 companies.
What is the ratio of the total central angle formed by sectors R and S to the total central angle formed by sectors U and V?
Option 1: 1 : 4
Option 2: 2 : 1
Option 3: 1 : 2
Option 4: 3 : 1
Correct Answer: 2 : 1
Solution :
Total number of cars sold = 5000
Sector R and S = 17% of 5000 + 13% of 5000
$=850 + 650 = 1500$
Sectors U and V = 6% of 5000 + 9% of 5000
$= 300 + 450 = 750$
So, the required ratio = 1500 : 750 = 2 : 1
Hence, the correct answer is 2 : 1.
