If 1/5 of the total cars are red, 20 of the 100 cars are red (since 1/5 is 20).
If 1/3 of the sports cars, of which we have 25, are red, then 25/3 of the sports cars are red.
Since we have 20 total red cars and 25/3 of them are sports cars, then the rest of them must be red sedans:
Total red cars - red sports cars = red sedans
which simplifies to
