A can do a work in 15 days and B in 20 days. If they work on it together for 4 days, then the fraction of the work that is left is : A.1/4 B.1/10 C.7/15 D.8/15
A's 1 day work=1/15, B's= 1/20, Combined 1-day work=(1/15 + 1/20= 7/60); Combined 4 day's work= 28/60, therefore work left=(1-28/60)=32/60 or 8/15
