As per graph,
other expenses = 15 % of total expenditure.
As we know that the angle made on center in a circle is 360°
Since 100% made an angle 360° in a circle.
therefore 1% made an angle 360° / 100 in a circle.
therefore 15% made an angle 15 x 360° / 100 in a circle.
Central angle for 15% =15 x 36° / 10
Central angle for 15% =3 x 36° / 2
Central angle for 15% =3 x 18° = 54°
From above given chart ,
selling of white colours' cars = 26%
Since Cars of golden colour are 20% less popular than white coloured cars.
Required answer = 26 - 20 = 6%
Riya's overall percentage of Marks in all subject = (80 + 53 + 86 + 60 + 80 + 78)/6 = 437/6 ? 72.8%
