A committee is reviewing a total of 40x black-and-white films and 10y 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?	Pick:
A) 50/52
B) 55/52
C) 60/52
D) 40/52
E) 30/52
Say x=y=10. In this case we would have:   40x=400 black-and-white films;   10y=100 color films.   y/x%=10/10=

1% of the black-and-white films, so 4 black-and-white films and all 100 color films, thus total of 104 films were selected.   Color films thus compose 100/104=50/52 of the selected films.   50/52nswer: 50/52
