At a monthly meeting, 3/5 of the attendees were males and 7/8 of the male attendees arrived on time. If 4/5 of the female attendees arrived on time, what fraction of the attendees at the monthly meeting did not arrive on time?  Choose the most appropriate option.
A) 47/200	B) 31/200	C) 17/100	D) 11/100	E) 7/50
Males who did not arrive on time are 1/8*3/5 = 3/40 of the attendees.   Females who did not arrive on time are 1/5*2/5 = 2/25 of the attendees.   The fraction of all attendees who did not arrive on time is 3/40 + 2/25 = 31/200   The answer is 31/200.
