In Township K, 1/4 of the housing units are equiped with cable Tv. If 1/10 of the housing units, including 1/3 of those that are equiped with cable tv, are equipped with videocassette recorders, what fraction of the housing units have neither cable tv nor videocassette recorders?
Answers:	A) 23/30	B) 11/15	C) 7/10	D) 1/6	E) 2/15
1/4 -- cable TV (This includes some data from video cassette recorder)   1/10 -- video cassette recorder including 1/3(equiped with cable tv) i.e. 1/3(1/4) = 1/12   therefore only video cassette recorder = 1/10 - 1/12 = 1/60   Total = 1/4+1/60+neither cable tv nor videocassette recorders   1 = 4/15 + neither cable tv nor videocassette recorders   therefore neither cable tv nor videocassette recorders = 1-4/15 = 11/15   Hence 11/15.
