At a monthly meeting, 3/5 of the attendees were males and 7/8 of the male attendees arrived on time. If 9/10 of the female attendees arrived on time, what fraction of the attendees at the monthly meeting did not arrive on time?  Choose the correct choice from the following
A) 23/200  B) 11/100  C) 7/50  D) 3/20  E) 4/25
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 1/10*2/5 = 2/50 of the attendees.   The fraction of all attendees who did not arrive on time is 3/40 + 2/50 = 23/200   The answer is 23/200.
