You can put this solution on YOUR website!
Of 200 cars, 50% red leaving 50%, or 100, that could be green.
Of 200 cars, 60% are 4 door, leaving 40%, or 80, that are 2 door.
Of 200 cars 70% , or 140, have alloy rims.
Out of these, with no other restrictions, the second would be the most limiting factor, so at most 80 cars could be green two-door cars with alloy wheels.
