Study the pie chart and answer the question that follows.

If 3 companies with largest market share are combined together in pool A and the remaining ones are clubbed in Pool B.

What is the approximate difference between the area (in degrees) of Pool A and Pool B?

Correct option is A

Given:

Market share of companies:

Hero MotorCorp: 35.3%

Honda Motorcycle & Scooter India: 25.1%

Bajaj Auto: 19.2%

TVS Motor: 13.5%

Yamaha India: 4.2%

Royal Enfield: 2.7 %

Formula Used:

​$$\text{Angle} = \left(\frac{\text{Percentage}}{100}\right) \times 360^\circ$$​​

Solution:

Top 3 companies (highest market share):

Hero MotorCorp, Honda Motorcycle & Scooter India, Bajaj Auto

Pool A = 35.3% + 25.1% + 19.2% = 79.6%
Pool B = 13.5% + 4.2% + 2.7% = 20.4%
Angle for Pool A$$=\frac{79.6}{100} \times 360 = 286.56^\circ$$​​

Angle for Pool B =$$\frac{20.4}{100} \times 360 = 73.44^\circ$$​​
Difference = $$286.56^\circ - 73.44^\circ = 213.12^\circ$$​​

Approximate difference = 213°.
