Statement I,
40/100 xx = 20/100 x 50 ? x = 25
Statement II,
30/100 x y = 25/100 x 72 ? y = 60
From both statements,
x : y = 25 : 60 = 5 : 12
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%
