A committee is reviewing a total of 40x black-and-white films and 4y 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 the correct choice from the following answers.
A) 20/11
B) 16/11
C) 17/11
D) 10/11
E) 19/11
Say x=y=10. In this case we would have:   40x=200 black-and-white films;   4y=40 color films.   y/x%=10/10=

1% of the black-and-white films, so 4 black-and-white films and all 40 color films, thus total of 44 films were selected.   Color films thus compose 40/44=10/11 of the selected films.   Answer: 10/11
