Answer 2

50%=cars

30%=motorcycles

50%+30%=80% 100% -80%=20%

remaining vehicles ,i.e.,vans =40

remaining percent=20%

so,40 vehicles =20%

number of motorcycles=by applying unitary method

40 20%

x 30%

40 x 30% =20x

1200 =20x

x =1200/20

x=60

=Number of motorcycles are 60.

new percent of cars=50% - 20% (Because 40 vehicles =20%)

=30%

=20% cars are there now.
