A committee is reviewing a total of 20x black-and-white films and 8y color films for a festival. If the committee selects y/x% of the black-and-white films and all of the color films, what fraction of the selected films are in color?	Choose one: A) 40/41 B) 20/41 C) 30/41 D) 60/41 E) 80/41
Say x=y=10. In this case we would have:   20x=200 black-and-white films;   8y=80 color films.   y/x%=10/10=

1% of the black-and-white films, so 2 black-and-white films and all 80 color films, thus total of 82 films were selected.   Color films thus compose 80/82=40/41 of the selected films.   40/41nswer: 40/41
